asterisk users - Dec 2005 - No sound problem, chan_sip.c:3451

Hi.

I'm trying to hook up the SIP-Communicator softphone. When I dial their 
is no sound and on the asterisk box the following is displayed:
    chan_sip.c:3451 process_sdp: Unknown SDP media type in offer: video 
22222 RTP/AVP 26 34 31

How can I fix this problem?

Thanks in advance.

Either enable videosupport for chan_sip or disable it in your softphone.
