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)
Ethernet II, Src: Grandstr_0b:a5:3e (00:0b:82:0b:a5:3e), Dst: Dell_3e:05:ac (00:13:72:3e:05:ac) Internet Protocol, Src: 10.1.10.184 (10.1.10.184), Dst: 10.1.10.1 (10.1.10.1) User Datagram Protocol, Src Port: avt-profile-1 (5004), Dst Port: 13608 (13608)
   Source port: avt-profile-1 (5004)
   Destination port: 13608 (13608)
   Length: 16
Checksum: 0x8e5f [correct]
Data (8 bytes)

Data is 8 x null (00)

regards,

Drew

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
