Frequently Asked Questions
Q1: Who is the Grandstream GRP2615 for? +
The GRP2615 is designed for executives, busy receptionists, call centre agents, or professional managers who handle many concurrent calls. Its 16 SIP accounts and 40 BLF keys make it ideal for high‑volume communication environments.
Q2: Does the GRP2615 work with PTCL analog lines in Pakistan? +
No, the GRP2615 is a pure VoIP phone. To use it with PTCL analog lines, those lines must be connected to an FXO gateway (e.g., Grandstream HT841/HT881) or a UCM series IP PBX, which bridges analog trunks to the SIP network. The phone then registers to that PBX as a SIP extension.
Q3: What power options does it have for Pakistan’s 220V supply? +
The GRP2615 includes integrated PoE (802.3af). If your network switch provides PoE, no separate power adapter is needed. If you do not have a PoE switch, you can use a standard PoE injector or the included universal 12V DC power adapter — both products work seamlessly on Pakistan’s 230V/50Hz grid.
Q4: What is the battery capacity for the handset? +
The GRP2615 is a wired desk phone. It does not have a battery and relies on the base unit for power during operation.
