[OpenSIPS-Users] URGENT: Sip providing not sending 407 challange

[Satish Patel]

Hi,

I just put new SIP provider info in registrant table for UAC auth and it is
showing

 state:: REGISTERED_STATE

but my calls failing and in ngrep i check somehow remote SIP providing not
sending me 407 auth challenge packet, is it possible?

1. INVITE ---- SIP Provider
2. SIP Provider -- 100 Trying
3. SIP Provider -- 403 Auth failed


I am not seeing any 407 challenge packet, why SIP provider not sending 407?
