[SR-Users] Add PSTN gateway with authentication credentials

[Daniel-Constantin Mierla]

Hello,

the documentation of the uac module has the relevant bits in the example
of uac_auth() function:

  -
http://kamailio.org/docs/modules/stable/modules/uac.html#uac.f.uac_auth()

In short, before relying to the PSTN gateway first time, set the
failure_route handler as in the example pointed above, then in the
failure route be sure the appropriate avps are set to the username and
password the PSTN gateway expects.

Note that there is a limitation with the above approach -- if the PSTN
gateway is doing CSeq strict checking (you should notice that after
sending the INVITE with credentials, the response is 500), then you have
to load the dialog module and enable cseq tracking and update for calls.
But try first with uac only, could be that the pstn gateway provider
uses a kamailio/ser based proxy for authentication.

Cheers,
Daniel
