IAX trunks and MTE 8.0 Auto congesting call due to slow response

Posted by trinicom on Fri, 12/16/2016

Is anyone else getting Auto congesting call due to slow response in their IAX trunks?
We got this in 7.5 and still with 8.0.

We like to use IAX to tie back into our edge servers.

thanks

Found the issue!
its a bug in Thirdlane,
When you create an IAX trunk in either 7.5 or 8 it writes the registration string to iax.conf BUT does not write the General settings.
it writes this
register => testtrunk:password@myserver.com ; testtrunk

but does not write this part

[mytesttrunk]
qualify=1000
nat=no
secret=password
host=myserver.com
username=testtrunk
context=from-outside
type=friend
disallow=all
allow=ulaw
allow=alaw

the work around is that you can add the 2nd part in the iax.conf and it works, you can save the changes on the trunk in the MTE but it will not save it to the iax,conf however it will not over write your changes.

I hope this gets addressed in a future update soon

Configuration is stored in the database - i believe it is only the registration that ends up in the file. For SIP we actually allow using the file based configuration as an option, perhaps we can do the same for IAX in the future.

I wonder how many people use IAX?
