[Serusers] SER & Asterisk (IVR problem)

[sip]

So... if I understand this correctly, you're having problems with diverted calls FROM the Asterisk IVR not being able to authenticate on SER? 

Could you just add the Asterisk server to the trust tables and skip the auth process for calls coming back or would that create problems?
