[SIPForum-discussion] 185 ringing / 199 trying

[Malay Si]

If a SIP element gets a response which is having unknown "reason-
phrase" (not define in RFC 3261) then the element treated the response
as follows.

 

Wrong 1xx series---183(session progress)

Wrong 2xx series---200

Wrong 3xx series---300

Wrong 4xx series---400

Wrong 5xx series---500

Wrong 6xx series---600

 

In your case A will treat the response as a 183 (session progress) and
will wait for the final response.

Sip does not allow to send response for a response. wait for final
response or u can send cancel to terminate call as per your application
requirements.
