Jabber for Android over vpn

Hi,

We have an issue with Jabber for Android over VPN, the problem as follows:

Jabber for Android over VPN is registered to CUCM and when I tried to call desktop IP phone only one way audio, we also have Jabber for IPhone also connected over VPN and can call the desktop phone with no issue (both parties can talk and hear)!!!!

what might be the cause of this issue?

Regards,

I would check the firewall and confirm that the UDP ports Jabber requires are open.  It is mostly likely a dynamic UDP port range on the inbound side (outside into the firewall) that is being blocked.
