[OpenSIPS-Users] B2BUA not passing ACKs

[opensipslist at encambio.com]

Hello list,

According to the example:

  http://www.opensips.org/Resources/B2buaTutorial#toc13

...implementing the prepaid service should handle INVITE, ACK, and
BYE. Strangely the XML file includes only the BYE scenario:

  <rules>
      <request>
          <bye>

I don't know enough about the B2BUA modules to say for sure, but it
would seem that the online example is missing 'ACK' at least.

When I copy the XML code and config code 1:1, my B2BUA
implementation of the prepaid service sends the initial INVITE,
receives the OK, but as the UAC (caller in the diagram) sends the
ACK the B2B (green line in the diagram) does not pass it onto the
media server.

Is there a bug in the online XML code for the prepaid scenario?

Regards,
Brian
