While in a call, Example 1 below, the registration timed out and was removed by the VCS. Once that happened, the SIP to SIP call ended abruptly at 16 minutes.

The message only happens when specific users (User A in this case) are in a SIP to SIP call with EP1.
User A: Jabber 4.5 from location A
User B: Jabber 4.5 from location B
EP1: Tandberg Edge 95 9.3.1
Example1: User A on Jabber calling EP1 using SIP URI. Call continues for exactly 16 minutes and then disconnects with the error
"Registration was not refreshed in time and endpoint failed to respond to IRQ"
Obviously the endpoint is not responding to the VCS or the response is getting blocked.
After this error happens, authentication gets rejected for "Received from unauthenticated source" for 5 times before it requests new registration and is accepted.
Example2: User B on Jabber calling EP1 using SIP URI. Call continues eternally with no errors in the log.
So it only seems this endpoint is ignoring the VCS requests with specific calls.
Example3: User A on Jabber calling EP1 using H323 ID. Call continues eternally without any error.
I have the log, but do not want to post in public.
MK: I apologize for not making this a new message originally.
