Hi Team,

I had experience with Cisco IP Phone model 7841 , and 7821 which have registered through sip protocol on cucm ver 12.5.1.11900-146 and it cause the below issues.

1. Delay on an external outbound call
2. Delay on an internal inbound call.


Let me know if this got solution to resolve the matter.
