<DIV><SPAN class=984045919-14022006><FONT face=Arial size=2>At our customer site
i've installed one asterisk server with 20 Grandstream GXP2000's. Firmware
1.0.1.9. When someone dials the customer, the receptionist picks up, and does an
attended transfer (the 'grandstream way') to a collegue. Most of the times
this goes ok, but sometimes, when the receptionist puts the call on hold, and
tries te reconnect to the caller there's only one-way-audio. The receptionist
can hear the caller, but the caller cannot hear the receptionist! I've done
several ngreps etc. and I can see that traffic is going from asterisk to the
receptionist phone, and vice versa.</FONT></SPAN></DIV>

<DIV><SPAN class=984045919-14022006><FONT face=Arial size=2>I can predict when
this is going to happen: when the receptionist places the call on hold, the
caller doesn't hear musiconhold. If the caller does hear musiconhold then
everythings goes well. Asterisk states in both occassions that it is starting
musiconhold, and again, with ngrep i can see the RTP traffic going from asterisk
to the caller and vice-versa. </FONT></SPAN></DIV>

<DIV><SPAN class=984045919-14022006><FONT face=Arial size=2>I'm thinking this is
a problem with the Grandstream phones, but I'm not sure. I upgraded to of the
phones to firmware 1.0.1.12 today, and will contact the customer tomorrow if it
had helped. Has anyone ever seen this kind of behavior with
Grandstreams/Asterisk?</FONT></SPAN></DIV>
