Registering Range Networks Dev Kit / OpenBTS with Restcomm

Question

I'm trying to configure OpenBTS 4 to use Restcomm for SIP registrar, voice and SMS proxy. Looks like OpenBTS has a minimal SIP stack and expects not to be challenged when registering mobile devices as sip clients. I see this question addressed for FreeSwitch: http://wiki.freeswitch.org/wiki/OpenBTS

Can Restcomm be configured to accept registration requests without auth challenge?

Answer 1

Jean Deruelle provided the answer I needed:

https://github.com/Mobicents/RestComm/issues/29

A new config tag authenticate has been added to the restcomm.xml configuration file. Set it to false to disable auth for incoming requests (REGISTER, INVITE, MESSAGE) from SIP Clients If set to true Restcomm will authenticate users and incoming messages from those users true

 <!-- If set to true Restcomm will authenticate users and incoming messages from those users -->

                <authenticate>false</authenticate>
