Solved outbound to tollfree.alzacar.com fail with 503 works with asterisk

[Leon Zetekoff]

Hi there...

quite awhile ago I setup my trunks and one of them is for sending tollfree calls to tollfree.alzacar.com. Now that I have migrated my synagogue over from asterisk it seems this is no longer working. I get a 503 error:

SIP Server/Call Manager ID: 12294
Call or Registration to 8005551212@(Ln.10002@AlcazarTollFree) has failed. 162.212.218.16 replied: 503 Service Unavailable - Route Advance; from IP:162.212.218.16:5060
This used to work a few months ago when I implemented this.

My outbound routes is this:



I've attached the asterisk logs showing it works.

Here's the link showing how to connect:

https://www.alcazarnetworks.com/termination_tf.php

there is no user/pass for tollfree termination.

Can someone please try and duplicate this and see if they can get it to work and if not how can we fix it please?

Thanks leon

Attached is a full log from 3cx showing a call to 8003733411 being failed by alzcar and then works on voip.ms

I suspect that it may have something to do with the Caller ID you are sending, or lack thereof. Some toll free services do not allow calls, that do not send a valid caller ID.

HI @leejor -- no caller id is being sent. Thanks leon

 

[leejor]

Are you saying that you do not send caller ID? That then, may be the issue. Most toll free destinations insist on a number so that they can track callers. They are paying for the call after all.

Hi there...no I am sending caller id.

Question: Is there still a trunk limit on the various versions? If so what are they for free and pro?

Thanks leon

Ok I fixed it. I had outbound callerid set to 484-331-3245. I expected the PBX to strip the '-' once I removed the '-' it now works. word to the wise.
