Your call cannot be completed as dialed - IAX2


(Todd Schacherl) #1

I’m trying to get two Freepbx systems to talk over an IAX2 trunk and I’m not having much success. Both systems are behind firewalls, one a Fortinet 60E and the other is a Meraki MX64. I’ve opened UDP 4569 ports on both and pointed them to their respective servers internally.

When I try to dial an extension on the other system I get the message, “your call cannot be completed as dialed, please check the number and dial again.”

I’ve created an outbound route that looks for 5XXX and points to the AIX trunk. On the other system it’s similar except the dial pattern uses 4XXX.

I see nothing on the receiving system as far as the asterisk logs. On the calling server’s logs I see the following:

#2

The calling server didn’t even try to access the trunk, because you have some restriction module (Extension Routes, Class of Service) in place that seems to be denying access from 4003 to the Outbound Route that matches 5001.


#3

Once you get past the issue Stewart1 mentioned, you might want to try tweaking your configs to match closer to what’s mentioned in this older ticket(and the wiki info mentioned within) if you’re still facing issues.


(Todd Schacherl) #4

Thanks Stewart! That was it. The setting for allowed trunks was not checked for the iax trunk. Was not aware of that setting.
