[Asterisk-Users] cisco phones problems

[Edwin Lam]

hi folks.

we recently deployed 10 Cisco 7960G w/ SIP firmware 7.3 on our network and
we start having problems of dropping calls (actually the calls wasn't dropped
it just the sound was muted for about 5-10 seconds, but most users will think
the call dropped and hangup/redial). i've check the console output.
there was a lot of messages like the following:

Sep 28 15:00:49 NOTICE[8182]: chan_sip.c:6678 handle_response: Peer '3289' is 
now TOO LAGGED!

we're running Asterisk 1.0.9 on Debian Sarge w/ custom kernel 2.6.12, strange
thing is the system works fine with 2 Cisco phones & 8 Grandstream phone
before, until i replaced the Grandstreams with Ciscos. the following is
typical setting in sip.conf:

[1234]
context=default
type=friend
host=dynamic
username=1234
secret=test123
mailbox=1234
callerid="John Smith" <1234>
qualify=yes
dtmfmode=rfc2833

any thoughts why this is happening?
