[cisco-voip] MRA calls dropping

[Lelio Fulgenzi]

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.

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 at 192.168.10.25:53171;transport\=tls" To="sip:6656002 at CUCMS01.BANANA.COM<mailto:sip%3A6656002 at 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!
