Hello eveyone,
I was wondering if anyone using Cisco Jabber and a VPN connection has experienced something about this.
We have an ASA5510 that we use as VPN concentrator. We have deployed Cisco Jabber, either on laptops (mac or pc) or on iPhones & iPads.
We are able to successfully establish a VPN connection on the remote client and Jabber will register correctly.
The issue comes when we want to do the first call. No matter what, the first call will never have audio, we need to do a dummy call and then, the second and subsequent calls will work correctly.
Do you know if this is an expected behaviour when connecting through a VPN? We have been told that this is an expected behaviour as the tunnel doesn't know how to handle packets the first time, but, would this be true?
If we do the same connecting the device to the corporate network (wired o wireless), the first call will work as expected the first time.
Thanks!
