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

So sorry, but do you know of any tutorial using the auc module for authenticating against a PSTN gateway?

I don't know anything about hashing outgoing passwords, not sure if it's possible. However here passwords are in database.

Any ideas on adding credentials to my PSTN gateway?

I would like to not have the password en clear text in my kamailio.cfg but if it's not possible that's OK.

I'm trying to use a PSTN gateway with Kamailio for outbound - and incoming - calls.

Everything seems to be routed correctly, except the PSTN gateway denies the call due to missing authentication.

How do I add credentials for my PSTN gateway in a secure way?

Best regards,
Michael
