MRA calls dropping
Both internal and external, multiple users, multiple locations

We are seeing call drops, and the only things the logs (on the Expressway
E's) show is a Bye coming from CUCM.

tvcs: Event="Request Received" Service="SIP" Src-ip="10.1.28.210"
Src-port="25845" Dst-ip="10.2.9.165" Dst-port="7001"
Call-serial-number="b5ef5cdf-c039-48ec-91af-8ef6f4f4204c"
Tag="dfd1d116-6100-48f6-8dcf-d2efe0b6f552" Protocol="TLS" Method="BYE"
Request-URI="sip:4ed5aa08-624f-82a4-8c7f-6863f6545aa9@192.168.10.25:53171;transport\=tls"
To="sip:6656002@CUCMS01.BANANA.COM" Level="2" UTCTime="2021-11-24
16:10:45,389"

CUCM is 12.5
Expressway is v14.0.3

Just wondering what to check...


Thanks!

We saw this with people that had internet options that weren’t the greatest. To help resolve we adjusted a timer, and actually enabled/changed a FW port. Both made a huge difference. However I don’t remember if we were getting drops based on bye, or timeouts resulting in the bye. Its been a while. But I can get the info if you like.

First thing I’d check if they are all dropping at around 15 minutes. There was a firewall setting that by default dropped mra calls every 15 minutes.

Grab the CallManager traces. They should show why CUCM is sending a BYE.
