I have a sip trunk configured with a sip provider in IP Office v2 R11.1 behind a Meraki firewall
No signal issues for incoming and outgoing calls, but no audio in both directions when answering call, and system status shows 100% packet loss with media IP even though there is a ping from IPO
I set and ran a STUN address for Google in the LAN1 network topology which provides the full cone NAT & public IP, and fixes the audio issue for only a few hours
Firewall engineer advised me that the Meraki doesnt do sip alg inspection.
and I should use either :
STUN server,
Is there a free STUN server that runs permanently without any restrictions or does it require a subscription?
Or
Configre IPO to correctly send the public IP in its header, how is it done?
Any advice appreciated.
