[SIPForum-techwg] Quintum Gateway not sending 180 Ringing

[라스토기]

Hi,
I think you should check if Quintum Gateway is receiving 180 ringing from called party. If you get this 180 ringing randomly, then I suspect Quintum Gateway could be unstable but pls check if called party is sending this or not.
In case called party is not sending, then Quintum Gateway will never send it to you but otherwise Quintum Gateway has some problem.
Hope this helps.

Hi All, 

I am connecting from Verso (C4 and C5) platform to Quintum Gateway. I make a call and do not get a ringback from Quintum Gateway. I took traces and they show that after "100 Trying Message", it goes straight to "200 OK" or sometimes to "183 Session Progress". I do not have access to the Quintum Gateway as another person is doing the configuration on the other side. In a nutshell, what causes a SIP Server not to send a "180 ringing message".

Regards 
Mfana
