[SIPForum-discussion] Quintum Gateway not sending 180 Ringing

[Ngwenya Mfanasibili]

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
