Complaints about bad sound

Hello,

I have had some complaints about bad voice during calls with my Asterisk 1.4.

When I look in the CLI when a call is ongoing, I see the following errors repeated by a lot.

[2009-07-30 15:58:50] WARNING[52272]: rtp.c:891 ast_rtcp_read: RTCP Read too short
[2009-07-30 15:58:56] WARNING[52272]: rtp.c:891 ast_rtcp_read: RTCP Read too short

[2009-07-30 15:59:16] WARNING[52272]: rtp.c:891 ast_rtcp_read: RTCP Read too short

Why is this, and does it have anything to do with bad sound results during calls?

Thanks in advance,

best regards.

Because Asterisk believes the other end of the connection is violating the RTCP protocol. This doesn’t directly affect actual voice quality (RTCP is used to signal quality information about the voice channel, not the actual voice channel), however it just might be due to some network problem that is in common with the one affecting the RTP voice stream.
