IP phone configuration overview
Last updated: 2026-07-15
Dromlik supports three ways to connect an IP phone to the PBX. Pick the one that matches your fleet, then follow the linked step-by-step page.
| Method | When to use it |
|---|---|
| Auto provisioning | Rolling out many identical phones. Applies preferences, codecs, and extension registration in one push, and lets you manage phones centrally from Dromlik. |
| Manual provisioning | Phones that don't support RPS redirection. You paste a provisioning URL into the phone's web UI once and the phone pulls its config from Dromlik. |
| Manual registration | Any standard SIP phone. You enter the extension credentials and PBX address directly on the phone. No central management. |
Auto provisioning transport
Two transports are available for auto provisioning:
- RPS (Redirection and Provisioning Service). The phone boots, contacts the vendor's redirection service, and is pointed to Dromlik. No LAN configuration needed.
- DHCP option 66. Your local DHCP server hands out the Dromlik provisioning URL. Use this when phones don't support RPS.
Manual registration
Register an extension on a phone by entering the SIP credentials and PBX address in the phone's web interface. This works with any SIP-compliant phone but does not give you central management, remote firmware upgrades, or provisioned function keys.
