Multiple ITSP

[Ly Tran]

Just got a test trunk to add to SipX, as a secondary gateway, but running into some problems. I'm able to receive phone calls to the new DID from the second ITSP, but making outbound does not go through it. It is going out through the primary. Trying to follow this setup here:
http://www.sipfoundry.org/web/mpicher/~/426137/blogs/-/asset_publisher/xfZRF9U0rLa7/blog/id/128906

However, I cannot add a new gateway with new branch/DID to the dialplan that was configured for the first ITSP. The first ITSP uses e.164 while the new ITSP does not. Created new dialplans for the second ITSP, but still doesn't work. Am I overlooking something?

I'm not sure how well that translates in 4.4 and also 4.6 (branches).

A couple of things you can do: dial only 10 digits at the phone. Let the
trunk take care of adding anything one provider requires beyond that. You
can also have only one gateway per rule but ceate duplicate rules for
testing and adding a prefix when dialing at the phone to use the test
gateway and stripping it before sending it to the provider. Once you are
sure the provider is accepting the call and things work, you should then
try to see how branches work.

Note: Trunking requires the provider to send a cause code back that allows
sipx to use the "other" gateway. Very few, if any providers do this. It's
more likely found on SBC's and gateway devices though. Until ITSP's start
using "486: Busy here" in an instance where the call paths are reached or
not allowed (like on international) it's really going to be hit or miss
that this type of behavior becomes (try this ITSP, if they can't do it or
its down, use another).

I think I had another thread on multiple ITSP's and things we could look at
doing when the trunk is registered but not authenticated, but it wasn't
received to well at the time.
