Hello Ramona,
We are attempting to use avpops and seem to be running into issues, using the latest
stream from CVS.
We are trying to change the domain portion of the ruri with a set of routable gateways,
using the serial forking example given in section 8.4 of your documentation
(http://www.voice-system.ro/docs/avpops).
So here is what we want to do. If a forwarded INVITE to gw1 fails, via a 404 or 408
response, use the next gw in the list, gw2, to route the request. 404 and 408s are noted
because we do not want a retry if the response is a 486 - other other potential negative
responses that are legitimate. Below is a snippet from ser.cfg of what we have been
working with, unsuccessfully. The difference between your example and what we are
attempting to do is that the example demonstrates a method for rerouting to completely
different URL. We only want to change the domain portion of the ruri.
Kind regards, and thanks ahead of time for guidance offered.
Chris
