As mentioned in the title, here I is the details I’ve stuck with this matter for 2-3 weeks now…
In my company there’s an Asterisk server setup previously (lets name it Server A) in HQ. My task was to setup 2 more asterisk server on our 2 remote company branches( lets name it Server B on Branch B, and server C on Branch C), so that the HQ staff can call the branches staff as if they’re in same building.
I have install the 2 servers B and C on branches B and C, I have configured everything, the SIP extension, iax2 trunks and works fine…meaning staff in branch B can communicate with staff in branch C, no delay or lagging what so ever great.
When I tried to connect ot HQ (server A) I have an issue, that is the extension in the branches can call staff in HQ, can talk and talk back…fine. HOWEVER the extension in HQ unable to call the extension on both branches B or C…keep getting “Your call cannot be completed as dial…”
I have stuck on this matter for quite some times now…have go through the config on the 3 servers, the firewall and even the company firewall…I even compare and tried various parameter change on the iax trunk setting many times…but still the same result.
Does anybody faced the same issue before?
Can anybody help me please?..I’m running out of area to look to troubleshoot.
