The GRP2602P is Grandstream's entry-level PoE desk phone from their modern carrier-grade GRP series. Zero-touch provisioning, solid NBN performance, 2 lines with 4 SIP accounts against the Yealink T31P's 2, and a backlit mono graphical display. For AU businesses committed to the Grandstream platform, or when the T31P is out of stock or priced higher, this is the correct entry-level choice.

NTK ScoreRecommended
Relevance18/20
This mature, business-focused SIP phone addresses a large Australian SMB market with practical calling features, though its entry-level controls suit lighter-use desks best.
Effort15/20
Zero-touch provisioning and mainstream PBX support reduce deployment work, but PoE, network configuration, platform caveats and inconsistent official documentation still favour administrator involvement.
Adoption16/20
Traditional phone controls, HD audio and favourable exact-model ratings support easy adoption, while the small display, PoE requirement and uneven support evidence create manageable friction.
Commercial value17/20
Low published Australian pricing, free fleet management and efficient PoE operation deliver strong value, although bulk discounts, quantified payback and stock continuity remain unproven.
Trust18/20
Current firmware, encryption, RCM compliance, open SIP and Australian distribution are reassuring; limited AU-specific reputation evidence and channel-dependent warranty support are the main caveats.
What to know before buying
Standard SMB using PoE and an authorised Australian seller: Recommended.
24/7 operations needing immediate local escalation: Recommended with caveats, secure an after-hours provider support agreement.
Regulated or post-2028 lifecycle deployments: further lifecycle and security assessment required.
Warranty pathway Changes recommendation
Grandstream's policy, last revised 3 December 2025, provides the manufacturer's one-year hardware warranty to Certified Partners rather than directly to end users; end-user coverage depends on the seller. Grandstream also warns that unauthorised online sellers may not receive warranty service: https://www.grandstream.com/grandstream-warranty-policy
A low advertised price can become false economy if the seller cannot provide an Australian return or replacement pathway.
Matters most to: Price-sensitive SMBs buying online, especially from marketplace or unauthorised sellers. · Confirm the seller's authorised status, written end-user warranty period and Australian return process before purchase; retain the tax invoice.
Local support accessibility Changes recommendation
Australian distributor support exists through CommsPlus, but published local hours are 8:30am to 5:00pm AEST Monday to Friday and parts of its support portal are partner-account gated. Grandstream's direct end-user path is primarily a web helpdesk.
A business with after-hours-critical calling may not have immediate local phone escalation unless its hosted-PBX provider or reseller supplies that service.
Matters most to: 24/7 venues, healthcare operations, emergency trades and businesses needing after-hours phone-based escalation. · Contract for after-hours support through the hosted-PBX provider or reseller and document handset replacement/escalation procedures.
Security-update evidence Changes recommendation
Grandstream lists an Australian defined-support period for the GRP2602P through 12 July 2028 or later and was still issuing firmware in June 2026, but the public commitment beyond that date is not established: https://www.grandstream.com/compliance
Deployments expected to remain in service well beyond 2028 may outlast the presently documented security-support horizon.
Matters most to: Regulated organisations and businesses planning a five-year-or-longer handset refresh cycle from 2026. · Obtain a written lifecycle commitment or plan a security review and possible handset refresh before the documented support horizon.
Common use cases: The GRP2602P is the most affordable SIP desk phone in this guide that still delivers reliable call quality and basic provisioning. It can suit secondary extensions in cost-conscious deployments, for example vet clinic consult room phones and back-of-house extensions in small office configurations are common deployments. For a main reception desk that handles high call volumes, step up to the GRP2634 or a Yealink mid-range model.
Who is this phone for?
Grandstream describes the GRP2601/P as the lowest-end GRP2600 Essential model; the GRP2602/P is the next model up, with 4 SIP accounts and 2 lines. It is a 2-line PoE desk phone with a 2.41-inch 132×48 backlit graphical LCD and zero-touch provisioning through Grandstream's GDMS platform.
Buy it for: single-line desks, break rooms, back-of-house positions, and any location where a basic reliable phone is needed and you're standardising on Grandstream hardware across your deployment. Also a viable choice when the Yealink T31P is unavailable or priced higher at AU retailers.
For most AU businesses choosing between Yealink and Grandstream at entry level, the decision comes down to price and availability on the day of purchase. Both phones perform similarly in AU SIP deployments. The GRP2602P uses a 132×48 backlit graphical LCD rather than a colour screen.
Do not confuse the GRP2602P with older Grandstream GXP models. The GRP series is Grandstream's current carrier-grade line. The GXP series is still supported but is an older design.

Build quality and design
The GRP2602P is a compact, slim phone with a cleaner industrial design than the GXP series. The GRP series was designed with modern zero-touch provisioning deployments in mind, and the hardware reflects that. The plastic body is standard for the price point, build quality is consistent with Yealink phones in the same tier.
The 2.41-inch display is a backlit mono graphical LCD, not a colour screen. Against the Yealink T31P it is marginally larger but lower resolution (132x48 against the T31P's 132x64), so it is not a display advantage. Caller ID and line status are legible, which is what this tier needs. The phone has four context-sensitive XML softkeys and two LED line keys. Grandstream's administration guide limits custom softkeys to speed dial, speed dial through the active account and voicemail; BLF and shared-line modes are configured as virtual multipurpose keys.
Call quality on Australian NBN
The GRP2602P supports G.722 HD audio and OPUS, matching the codec range of the Yealink T33G. Real-world call quality varies with the network, router, SIP provider and configuration.
Grandstream phones are compatible with all major AU SIP providers. Auto-provisioning via GDMS works with providers that support Grandstream's provisioning format. Maxotel and other managed SIP providers in AU support both Yealink and Grandstream provisioning.
Check the SIP provider's and router vendor's guidance. Many deployments work better with SIP ALG disabled, but some provider/router combinations require it to remain enabled.
Features
Zero-touch provisioning via GDMS. Grandstream's Device Management System allows mass provisioning from a cloud portal. Particularly useful for IT teams deploying 10+ phones across multiple sites. Yealink RPS provides zero-touch redirection to a provisioning server; Yealink YDMP is the closer analogue to GDMS for centralized device management and monitoring.
4 SIP accounts. Double the Yealink T31P's 2, on a phone in the same tier. This is the GRP2602P's real differentiator at this price point, not the display, which is mono on both.
4 programmable keys. Configurable as BLF, speed dial, or line keys. Limited compared to the GRP2634 or GRP2670, but sufficient for basic call handling at an entry desk.
OPUS codec. Opus is supported and includes mechanisms for adapting bitrate and improving packet-loss resilience, but actual benefit depends on end-to-end codec negotiation and network conditions rather than the NBN access technology alone. Not all entry phones at this price point include OPUS.
GRP Security Suite. Grandstream's carrier-grade security features including SRTP, TLS, and 256-bit AES encryption are included in all GRP phones regardless of tier.
What works / What doesn't
Pros
4 SIP accounts at entry price -- double the Yealink T31P's 2
GDMS zero-touch provisioning -- useful for multi-site IT deployments
Full GRP Security Suite (SRTP, TLS, AES-256) included at base level
OPUS codec support for variable NBN conditions
Compact, clean design fits modern office environments
Cons
100Mbps Ethernet only -- not Gigabit, limits PC passthrough speed
No Amazon AU listing verified -- check local AU retailers
Smaller AU retailer presence than Yealink T31P -- fewer stock options
4 programmable keys is limited for BLF monitoring -- step up to GRP2634 if needed
Australian pricing and where to buy
Australian availability for the GRP2602P is limited and intermittent. Our nightly StaticICE price tracking has recorded no current AU listing for this model since April 2026, so we are not quoting a price for it. Check DigiPhone, Acquire or your usual ICT supplier for current stock and pricing before ordering.
The GRP2602P's AU availability is narrower than the Yealink T31P. If you are buying a single phone and the T31P is in stock at a similar price, the decision comes down to brand preference. If you are standardising on Grandstream across your deployment, the GRP2602P is the correct entry point.
The GRP2602P is a solid entry-level SIP phone that competes directly with the Yealink T31P. Its 4 SIP accounts against the T31P's 2 are the real advantage at this price point; the displays are mono on both. The narrower AU retailer availability and no verified Amazon AU listing are disadvantages for single-unit purchases.
For Grandstream-platform deployments, this is the correct entry-level choice. For mixed or unbranded deployments where you're choosing on price and availability, check both the GRP2602P and T31P prices on the day.

What is the difference between the Grandstream GRP2602 and GRP2602P?
The GRP2602P adds PoE (Power over Ethernet) support. The GRP2602 requires a separate power adapter. If your switch supports PoE (802.3af), buy the GRP2602P to avoid the extra cabling. The P suffix consistently means PoE in Grandstream's naming convention across the GRP range.
Is the Grandstream GRP2602P compatible with Maxotel and AU SIP providers?
The GRP2602P implements SIP RFC 3261, but registration, feature and provisioning support must be confirmed with each provider. MaxoTel supports GRP phones, although its automatic provisioning is limited to handsets purchased from MaxoTel; third-party units require manual setup. Grandstream supports provisioning through GDMS/TR-069 or AES-encrypted XML configuration files, including delivery over HTTPS. Yealink RPS is a redirection service, not a configuration-file format; provider support for either system must be confirmed individually.
GRP2602P vs Yealink T31P -- which should I buy?
Both are entry-level 2-line PoE SIP phones at similar price points. The GRP2602P supports 4 SIP accounts against the T31P's 2 (advantage); both have mono displays. The T31P has wider AU retailer availability and a larger AU installed base (advantage for parts, support, and reseller familiarity). If you're building a Grandstream deployment, choose the GRP2602P. If you're undecided, choose on availability and price.
Does the GRP2602P work on NBN in Australia?
The phone can be used over an NBN internet service when the provider, router and connection permit SIP and provide suitable performance; operation should not be guaranteed over every internet connection or NBN type. Disable SIP ALG on your router, enable QoS for voice traffic, and register it with any AU SIP provider.
What does 'GRP' stand for in Grandstream model names?
GRP is Grandstream's carrier-grade phone series, designed for zero-touch provisioning and enterprise/carrier deployments. GRP is Grandstream's carrier-grade series designed for mass deployment. Grandstream continues to list and support GXP models separately, so GRP should not be described as having replaced the entire GXP series. GRP phones include Grandstream's Security Suite (SRTP, TLS, AES-256) as standard.
