We are experiencing an odd issue. We have many calls that don't drop, but some do after being up a minute or two.

The reason code is NORMAL_TEMPORARY_FAILURE and the sip status that is triggering that is 503 (Service Unavailable). With only one or two calls up at a time, I don't think it's a session limit issue (set to 1000).

Here is the console log from just before the 503 status - any help is greatly appreciated!
