No audio when calling web-client to web-client

[Matt Holder]

Hi,

We've been testing calls from web-client to web-client and neither end can hear audio. This is really strange as I can ring from mobile to a DDI, which is answered from the webclient and this works. Also, calls from the web-client to a mobile phone works and calling from a web-client to a fixed handset also works. Both ends using the web client are using 4G hotspot to minimise firewall blocks etc

Are the media server ports open on the 3CX server?

Can you try enabling PBX delivers audio on the extensions in question and does this help solve this ?

If this still fails run a PCAP trace from 3CX and see if you can see the call flow and audio streams.
