It is not a bug in Asterisk. Asterisk is following what the RFC says it MUST do. It is, however, a bug with your carrier. I would do the following: 1) Contact your carrier and ask why they are rejecting the 200 OK. 2) Assuming they won't change their behaviour, find out what they want in a response that declines an image media format. Without knowing what your carrier thinks the SDP should look like, any modifications you make to Asterisk will be guesses. 3) When you find out what they want, modify chan_sip so that it answers back with whatever they told you they want. This will occur in chan_sip's add_sdp method - in particular, look for the portion where add_sdp adds *either* the m_modem/a_modem strings to the SDP *or* the pre-formatted decline_m_line.
