Hello folks

I am having these two kind of messages in the console. After sometime the server do not accept any more calls

01/10/07 11:03:43:000 New WARNING[4955] rtp.c: RTP Read too short (2, expecting 131600)
01/10/07 11:03:43:000 New WARNING[4955] rtp.c: RTP Read too short (2, expecting 131600)
01/10/07 11:03:43:000 New WARNING[4955] rtp.c: RTP Read too short (2, expecting 131600)
01/10/07 11:03:43:000 New WARNING[4955] rtp.c: RTP Read too short (2, expecting 131600)

Then a lot of messages (from even unknow ip addresses)

01/10/07 09:11:22:000 New NOTICE[4064] rtp.c: Comfort noise support incomplete in Asterisk (RFC 3389). Please turn off on client if possible. Client IP: 213.137.81.67

Any idea will be appreciated.

hello, finally i can reduce these messages “RTP Read too short” after i review my remote connections and setup there the rtp port to one in the range defined in rtp.conf in asterisk.

related the “Comfort noise support incomplete in Asterisk (RFC 3389)” i found an article in www.asteriskgurus.com that tells that we should inactive VAD options (silence suppression) on remote extensions. I do it so and reduce the number of messages, however i discover that a lot of other ip addresses coming of other countries that seem to be hackers. So i redefined my firewall with more restrictions.

finally, the problem that after sometime i lost the sound persist, now i think it is related lost of registration of remote connections.

Please comment.
