Grandstream IP phones
Last updated: 2026-07-15
This page covers how to connect Grandstream phones to Dromlik, the default admin credentials, and how to factory-reset them.
Quick facts
| Auto provisioning | RPS and DHCP option 66 |
|---|---|
| Default admin | admin / admin |
| Factory reset | Web UI → Maintenance → Upgrade → Factory reset. |
Notes
Grandstream GRP and GXP series work with RPS. Older GXV video phones need manual provisioning.
Recommended method
PnP is easiest for factory-fresh phones. Use DHCP option 66 if the phones have already been configured elsewhere and you can't factory-reset them.
