Title: remote or local ringback tone for SIP
|
Hi Ira Kadin,
This depends upon whether the 180/183
has SDP in it.
If 180/183 contains SDP information and if
any of the codecs listed are supported by the GW, it is better to go for the
remote ringback tone which will come in RTP format, because sometimes there may
be announcement after this response.
If SDP is not present, then the GW can play local
ringback tone.
Regards,
Achuth.

Subject: [Sip-implementors] remote or
local ringback tone for SIP
Hi All,
My question is: how SIP GW can
determinate - weather to play local ringback tone while getting
180/183 provision response or it's
a remote ringback tone provided by terminator in RTP stream ?
In H323 GW I analyzed progress
Description of Alerting message (if set to 8 - remote ringback
tone).
What can be done for SIP protocol
?
thanks in advance
Ira
