SIP:415 unsupported media type

Hello all,

I’m facing issue in placing a call to h263 enabled user. My client using audio codec g729 when i making a call to end party who supports video call also . The end party returns “SIP:415 unsupported media type”


What SDP was sent in each direction?

Note I believe this is something like questing video when not supported, not something to do with codecs.
