hi,everybody

if anyone have deployed 7800or 8800 series ip phone in MRA scenario. there is no problem with jabber MRA fuction. I create an enduser for jabber and 7821 (the same user control jabber and ip phone). the phone firmware was 12.1 . and I'm using the Public CA on expressway-e and expressway-c. the problem is that when the ip phone outside the enterprise network ,when i enter the domain and user name/password . the ip phone failed to register. but once I login the jabber with the same user outside the enterprise network, the ip phone will success to register via MRA. is there any other config I need to notice?

Heloo,

Are you getting any error in the Cisco IP phone?
Did you check the public CA is listed in the document available in below URL,
https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/dx/series/ca/CA-Trust-List.docx
If it is included in the above list, could you please try to take a packet capture from the phone and share here.
