Re: [OpenSIPS-Users] Reroute B2B call after failure
Do you have some code example of how to do this?

Re: [OpenSIPS-Users] Reroute B2B call after failure
Thanks Ovidiu. I was using $rd before to send it to the Proxy, but $du looks to be better suited for that. And then $ru works perfect for representing the Primary or Backup SIP Gateway.

Re: [OpenSIPS-Users] Reroute B2B call after failure
On the OpenSIPSB2BUA instance, you need to be able to distinguish between an INVITE for the primary GW and the INVITE for the secondary GW. I would just send the INVITE from the OpenSIPSProxy instance with proper RURI (pointing to the right GW) to the OpenSIPSB2BUA instance.

Re: [OpenSIPS-Users] Reroute B2B call after failure
On the OpenSIPSProxy script in order to pass the call to OpenSIPSB2BUA I set the $rd variable to the OpenSIPSB2BUA IP address.

Re: [OpenSIPS-Users] Reroute B2B call after failure
Actually I guess I could just do the following On the OpenSIPSProxy use the uac_replace_to() and change the domain to be the Primary Gateway and then if it fails I can use the uac_replace_to() and set the domain to the backup. And then on the OpenSIPSB2BUA look at the To domain and use that to set my $rd. I will have to test it out but that sounds like it would work.
