Hello again,
Having problems with both incoming and outgoing calls from/to external numbers. One Way Audio, They can hear me but I can't hear them.
Firewall check returns OK.
Internal calls are fine.
SIP ALG is disabled (I have tried 2 different routers)
The router I am using is a Cyberoam Next Gen UTM device, but have tried using a cheap Zyxel too.
On testing we can see that the call generated from port 9004 is going out as port 38000 (or thereabouts) so I assume the return path is trying the same port (38000). Is this where STUN is required?
Strangely though, I have had two way audio working previously.
any advice would be well received.
Thanks,
Dave
