Cisco CP-8861-K9= | 3CX Issues

[defonotj3ss]

Hiya, I have a Cisco CP-8861-K9= UCM phone and I'm using a combo of USECALLMANAGER.NZ and youtube guides and such to help use it on 3CX, and after pulling the SEPMACADDRESS.xml file a few times it gets the config, the OK button goes white and upon pressing it, it shows up in 3cx as a phone,


and I can make a call and hear the audio, however about 30 seconds of it registering (including the call attempt) it changes back to "Phone registering" and won't go back onto the working registered screen, it works fine on sipgate but not 3CX, giving error code "UCM-closed-TCP", any ideas?

Hello,

do you mind sharing a screen shot of your you have configured on the phone itself? also do you mind adding the entries manual instead of using a template ?

Hello,
The attached pastebin is the config file sent over TFTP to the phone.
As it is an Enterprise model designed to be used with CUCM and not 3CX, this is the only way to config the phone.
It's using the manual SIP credentials from "Generic SIP Phone" aka the Yealink T46G template, as this was my previous phone.
It seems to connect then cut out from TCP, so not quite sure what the issue is but willing to try anything
Thanks

Does the phone have a section to add extension number etc if we can try manual addition of the sip? If yes, you can reset the phone and share a screenshot of the config page I provide you with some guidance
