Hi,
Per section 20.43 of RFC 3261, 306 seems like a good value.
"306 Attribute not understood: One or more of the media attributes
in the session description are not supported."
Note that it is not a SIP response code, but a code supposed to give additional
information about the response.
Regards,
Christer

Subject: [Sip] Warning header
Hi All,
If an initial INVITE from an endpoint offer contains the sdp as follows.
m=audio 15190 RTP/AVP 100 101\r\n
a=fmtp:18 annexb=yes\r\n
a=fmtp:101 0-15\r\n
a=rtpmap:100 UNACCEPTABLECODEC/8000\r\n
a=sendrecv
the terminating endpoint returns an error response 488 with a warning
header as follows.
Warning: 306 132.177.120.67:5060 "Attribute not understood"
Is 306 is correct response?
Thanks,
