Ringing SIP phone when GV has incoming call
bbs71364:
Apologizes- I'm using a Cisco CP-8861 3PCC phone. It is not registering, I have firmware 3.2.2 (Build: 5921EX) and I have followed the steps mostly here: https://www.ukvoipforums.com/viewtopic.php?t=229
Once I disabled call/answer without registering, inbound calls from GV rang the SIP phone, but I still can't dial from the SIP phone out.
I appreciate any assistance you can provide, I will also start a new post if needed. Please let me know what details you need from my end. Thanks!

Recent firmwares, including the one you mention, have a bug which prevents SIP phones from registering to them.
Try manually upgrading the firmware to the one which will be forced anyway in a few days time. If still not registering despite correctly following the instructions, can the Cisco phone be set to make calls even if not SIP registered?
