I just upgrade my T22P to firmware 7.70.0.130 and now my SIP account cannot register.

No errors. Or at least no useful ones.

hello,tracymission_it
I need some information
1. Could you tell me the last vesion before updata the fireware
2. After updata , have you re'enter the account and password again test.
3. You can restart test.
4. Except the T22P, are there have other phones issue?
I went from v.7.61.0.80 to v. 7.70.0.130 and ran into the issue.

I downgraded the phone back to v.7.61.0.80 to resolve. I would still like to work through this.

As a side note, I'm interested in finding if this phone (T22P) is compatible with the Sennheiser OfficeRunner.
Any update?? Is the G711 codec part of this firmware update? My phone seems to be missing it under 7.6.1

Apparently the update dmg'd the import certificates.
