Hi Steve,
The following packets match the offending warnings on the * console by
time and number of occurrences and . The SRC and DST ports vary between
calls (naturally) but the rest remains the same.
Frame 3 (60 bytes on wire, 60 bytes captured)

Internet Protocol, Src: 10.1.10.184 (10.1.10.184), Dst: 10.1.10.1

Grab a network trace (with e.g. Wireshark) and look at the payload type
and lengths of the RTP keepalive messages - if you post this information
to the list I'm sure someone will comment on what's happening.

Subject: [asterisk-users] Grandstream RTP keepalive packets
causing Asteriskwarning
Grandstream GXP-2000 with firmware 1.1.4.18 (beta) fixes an
issue where the phone did not send rtp keepalives when on
mute (resulting in disconnect from tech support hold and concalls)
A side effect seems to be that Asterisk pops the following
warning on the console...
Jul 26 14:06:35 WARNING[31654]: rtp.c:463 ast_rtp_read: RTP
Read too short
Grandstream say they are not sure what it is but "it should
not affect anything".
In other words, "Don't worry, be happy!".
Any thoughts/experience on this?
regards,
Drew
