Different carriers

[macaruchi]

Hi!
This is a question maybe with one answer, NO, but anyway I must ask
Is there a way to use different carriers simultaneously to do a manual call ?

I am having so trouble with connect my numbers sometimes I get an error from CONGESTION , Service Unvailable SIP cause,34 19 , I dont know to do

Yes. That's what Dial Prefix is for. If you set up one carrier as "Dial X" and the rest as "Dial 9", "Dial 8", "Dial 7", etc., you can use a different carrier on each campaign, yet another carrier for 3-way calls and (to the point:) yet another carrier for Manual Dial by using the "Dial Prefix", "3-Way Call Dial Prefix", and of course the "Manual Dial Prefix".

Method:

One carrier can be set up with _1NXXNXXXXXX in the dialplan entry.
Another can be set up with _91NXXNXXXXXX
Another can be set up with _81NXXNXXXXXX
Another can be set up with _71NXXNXXXXXX

Now you put X for _1NXXNXXXXXX, 9 for _91NXXNXXXXXX, 8 for _81NXXNXXXXXX, and 7 for _71NXXNXXXXXX in the chosen Dial Prefix field to select that associated carrier for each dial prefix.

You can also set up Failover (so a 2nd carrier is attempted if a call fails).

Contact your carrier to find out why they failed a specific call. Give the carrier the exact date/time/timezone and number called and they should be able to enlighten you as to why they rejected a call.

Really this is procedure to do , how to do a failover carrier if the call failed so use another carrier to try.

How to do this failover ?
