3cx on Amazon Lightsail (hosted)
We have a client that uses Zenitel / Stentofon Intercoms (TCIS-2)
We can register these directly with 3cx using just the domain, extension and SIP credentials (no provisioning)
Outbound calls from the intercom work flawlessly.
Inbound calls to the intercom are not working (rings but cannot answer and auto-answer not working)
However if the intercom is local the the PBX its works fine
behind an SBC intercom works fine.
There are two desk IP phones on the network - all using STUN
I have tried forwarding all ports to the intercom (5060, 5061, 9000-10999) but nothing works.
Any help would be appreciated.
Thanks,
