Grandstream GRP2602P Review — Australia 2026

Who is this phone for?

The GRP2602P is the entry point to Grandstream's modern GRP carrier-grade phone range. It is a 2-line PoE desk phone with a 2.8-inch colour screen and zero-touch provisioning via Grandstream's GDMS cloud management platform or any compatible provisioning server. 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 has a colour screen (vs T31P's mono) which is a practical advantage, but the T31P has a larger installed base in AU and more AU resellers carry it consistently. 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.

Specs at a glance

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 2.8-inch colour screen is a notable advantage over the Yealink T31P's mono screen. Caller ID and line status are clearer, and the colour display is easier to read in varied lighting conditions. The 4 programmable keys below the screen can be configured as BLF keys, speed dials, or line appearances.

Call quality on Australian NBN

The GRP2602P supports G.722 HD audio and OPUS, matching the codec range of the Yealink T33G. On a well-configured NBN connection with QoS enabled and SIP ALG disabled, call quality is excellent and indistinguishable from a Yealink phone in the same environment. 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. The standard SIP ALG advice applies: disable it on your NBN router before provisioning any SIP phone, Grandstream or Yealink.

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's RPS system is equivalent for Yealink deployments.
• Colour screen. The GRP2602P has a 2.8-inch colour screen vs the Yealink T31P's mono screen. For a phone at this price point, this is a genuine differentiator for basic call management visibility.
• 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. Supported, which is important for good performance on variable-quality NBN FTTN connections. 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

Australian pricing and where to buy

The GRP2602P is stocked by UMart, MSY, MegaBuy, and Computer & Parts Land in AU. Pricing typically sits around $62-$89 AUD for a single unit. Prices on this page are updated nightly from StaticICE. 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.

Verdict

The GRP2602P is a solid entry-level SIP phone that competes directly with the Yealink T31P. The colour screen is an advantage at this price point. 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. They regularly alternate on who is cheaper.

Frequently asked questions

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?

Yes. The GRP2602P works with all SIP-standard providers including Maxotel, Vonex, MyNetFone, and others. Grandstream phones support standard SIP provisioning via HTTPS configuration files, which most AU managed SIP providers support alongside Yealink's RPS format.

GRP2602P vs Yealink T31P -- which should I buy?

Both are entry-level 2-line PoE SIP phones at similar price points. The GRP2602P has a colour screen (advantage). 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?

Yes. It is a SIP phone that works over any internet connection including all NBN types. 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. It is the current recommended series for new deployments, replacing the older GXP series. GRP phones include Grandstream's Security Suite (SRTP, TLS, AES-256) as standard.
