Hello,
We have CUCM 10.5.1.10000-7 and using Jabber 10.5.2 on a Samsung cell phone. What we are noticing is when local is placed, it is successful. When a LD call is placed we here dead air When LD call is placed placed by a deskphone, with the exact same DP, CSS, etc. it is successful.
The Jabber client has no issues dialing internal numbers or local numbers. It is using its own data connection. If anyone has any troubleshooting steps, or has encountered something similar please let me know.
Thansk,
AK
