[SR-Users] Kamailio PSTN with User/Pass authentication

[Infinicalls Infinicalls]

Hi,
 I am trying to add PSTN gw for terminating my calls. I have changed
the IP in the kamailio.cfg file, but this provider wants digest auth
and so I need to pass api/pass to them. Can somebody guide me how and
where to add the username+pass to the config file.

thanks

regards
