If you have a phone that won't make / receive calls, stuck on dial tone when calling, etc., try the below before escalating:
- Reboot phone - Disconnect the ethernet cable from back of phone, wait a moment, then plug back in to restart phone.
- Verify connection - Verify the network connection at the wall and into the phone is good (cable and jack). Replace if needed.
- Verify extension - We've had a few issues where extensions will just disappear from Mitel. Verify the phone extension is still in the system.
If you verify that everything is good but it's still not working, escalate a ticket to Prime.
If it's a widespread issue, and many users are saying they are having issues calling, escalate a ticket to Prime, but also contact Comcast to verify our SIP lines are working.
TBD - Contact info for Comcast
