Hi Brett, Can you please throw light on a query regarding the usage of PAYLOAD TYPE in SDP media descriptor line. For G729,G729A and G729B , can you please specify whether we can use the dynamic payload types supported by necessary attributes i.e a parmeter that would from an RTP payload type number (as used inan "m=" line) to an encoding name denoting the payload format to be used. It also provides information on the clock rate and encoding parameters. It is a media-level attribute that is not dependent on charset.
For Ex: m=audio 1564 RTP/AVP 96 8 18 97 98 a=rtpmap:97 G729/8000 a=fmtp:97 annexb=no... Can 97 be used as PT for g729a. m_e...@yahoo.co.in> wrote: > From: sampat patnaik <sam_e...@yahoo.co.in> > Subject: PAYLOAD TYPE FOR G729 A and G729B > To: "sip-implementors@lists.cs.columbia.edu" > <sip-implementors@lists.cs.columbia.edu> > Date: Wednesday, 13 November, 2013, 12:26 AM > Hi > Experts, > I > have a query regarding this PAYLOAD type in MEDIA DESCRIPTOR > line of SDP which goes like this .. > As > per IANA , the PAYLOAD type for codec type G729 is static and is assigned as > 18.However i would like take a confirmation on my doubt that > the same static value is used for G729ANNEX A and G729 ANNEX > B as well > or it is dynamic allocation. > Can any of our experts throw light > on this and it would be great if u can support your reply > along with IANA/UNIVERSAL standards of numbering > plan. > RegardsSam > _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
