No audio when using Jabber from AnyConnect Devnet Sandbox
I've reserved a UCCX 12.5 sandbox. Everything in the sandbox machines works fine. I can use Jabber in the RDC machine in sandbox LAN.
But when I tried to install AnyConnect in my home computer and use Jabber, something is wrong. I can use Jabber to login and use my Computer to make calls to IVR 6000. But I cannot hear anything. There is no RTP package at all through VPN.
And I tried to use SIP Softphones to test. The same thing happened. I can make calls between VPN PC and LAN PC, but there is no RTP package.
I even tried to use 2 different softphones in the same VPN PC. They can make calls to each other, but still no audio.
1. Calls between 2 Jabbers in LAN: Good.
2. Calls between 2 Softphones in LAN: Good.
3. Calls between 2 Jabbers in LAN and VPN: no audio.
4. Calls between 2 Softphone in LAN and VPN: no audio.
5. Calls between 2 softphones in the same VPN PC: no audio.
To me, it looks like that AnyConnect VPN is dropping RTP packets, so there is no audio for all cases in the VPN PC. I've tried to use the same PC and softphone with other SIP server when VPN was disconnected, they are all good. So there is no problem with my PC firewall or softphone.
I reserved the UCCX 12.5 Sandbox to test it. I agree with you, we can chat and make calls but no audio.
Chat between Jabbers 1 and 2 successful in VPN
Calls between Jabbers 1 and 3 connection successful in VPN (but no audio can be heard)
I was able to connect calls from these three places (but no audio can be heard):
Jabber app on my desktop
Japper app in Sandbox RDP
Finesse Agent Web Gui
So my first thought is there are two possible issues:
There is a mechanism blocking audio between interfaces on a local machine (you cannot talk to yourself for good reason)
The RTP or other packet/port is blocked for some reason
However, another thing I noticed is there is no microphone or speaker connected to the Jabber agent in the Sandbox RDP.
I was eventually able to get the speaker recognized by going through Control Panel --> Sounds. However, no microphone could be found, even in the device manager. So that means using the RDP through the Sandbox for Jabber won't work. We must use Jabber on our Desktop of the Finesse GUI Dashboard (both in the VPN)
Speaker Fixed / Mic not found
My testing is concluded, as I believe I need a physical phone at my location to hook up to the Finesse Dashboard for proper configuration and testing and I do not have it at this time.
My notes, in conclusion,
I confirm that calls can connect but no audio can be heard between calls
It could be a designed mechanism or sandbox misconfiguration
The Jabber on the Sandbox RDP is configured for no audio and even when configured correctly there is no microphone
Use a local Jabber or the Finesse Dashboard to call
I will now bring this discussion to the attention of the Developer Advocate assigned to this sandbox so we can get some answers and / or a fix.
