Need help with NAP registration Empty Need help with NAP registration

Post by Alex Mon Feb 08, 2021 8:25 am

Hi,

We have recently installed a ProSBC HA pair, and we are hurrying to enter production.
I successfully managed to configure the incoming registrations, but I am facing problems with the outbound traffic.

For the outgoing calls, we send traffic from an ASTPP cluster (FS + OpenSips). I have configured a prefix for each carrier, and we're sending the calls from ASTPP with the needed prefix.
On the carrier that does not require SIP authentication, this works great, I just setup the NAP for them, and in the routing plart I strip the internal preffix.
For the carriers that require authentication, I ran into problems though.
I tried to configure the NAP configuring the user/pass in the Authentication Parameters, and also tried to enable Register to Proxy (and set it tp SIP:<username>@<carrierIP>).
When a call comes in, we pass it to the carrier, tey reply with 401 Unauthorized and SBC sends it to the originating FS.

How am I supposed to configure the authentication on the terminating carriers?

Thank you,
Alex
