Hello community
Since Jabber 12.5 update on iPhone and Android I'm facing a strange problem.
If I'm using MRA over 3G/4G mobile network and call an internal Jabber for Windows (Version 12.1.0 or 12.5) the call will disconnect after 3 seconds.
If I call a Hardphone - it works!
If I'm connected over WiFi - it works!
Environment:
CUCM 11.5.1.15900-18
Expressway-C X8.11.4
Expressway-E (dual nic) X8.11.4
Has anyone an idea?
Best regards
Michael
