Hi all, the RFC 3551 ( http://www.ietf.org/rfc/rfc3551.txt ) states the the PT 2 is reserved but it is being set to G726. And the same RFC says that G726 should have a dynamic PT.

but many hardphone/softswitch still use 2 for G.726 payload. If change to dynamic payload, it will be problem when talking to these devices. There are some devices which use static payload 2 and dynamic payload for G.726 at the same time. regards, Gang 2009/3/20 Benny Prijono <bennylp@teluu.com> > 2009/3/19 Rafael Maia <rmaia_lcm@hotmail.com> > >> >> Hi all, >> >> the RFC 3551 ( http://www.ietf.org/rfc/rfc3551.txt ) states the the PT 2 >> is reserved but it is being set to G726. >> And the same RFC says that G726 should have a dynamic PT. >> >> > > You're right, upon reading it again it seems that the use of PT=2 has been > deprecated, and dynamic pt should be used. > > Thanks! > > -benny > > > >> Rafael Maia >> >> > > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip@lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org > >

Exactly as Gang Liu said. IIRC, it was using dynamic PT in the development phase, but when it came into (compatibility) testing with other sip endpoints, we decided to use static PT.

Then it has been correct, I stand corrected. :) cheers, benny On Fri, Mar 20, 2009 at 3:54 PM, Nanang Izzuddin <nanang@pjsip.org> wrote: > Exactly as Gang Liu said.
