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! Sep 28 15:00:59 NOTICE[8182]: chan_sip.c:6672 handle_response: Peer '3289' is now REACHABLE! Sep 28 15:01:08 NOTICE[8182]: chan_sip.c:6678 handle_response: Peer '3201' is now TOO LAGGED! Sep 28 15:01:18 NOTICE[8182]: chan_sip.c:6672 handle_response: Peer '3201' is now REACHABLE! Sep 28 15:04:01 NOTICE[8182]: chan_sip.c:6678 handle_response: Peer '3289' is now TOO LAGGED! Sep 28 15:04:11 NOTICE[8182]: chan_sip.c:6672 handle_response: Peer '3289' is now REACHABLE! Sep 28 15:05:22 NOTICE[8182]: chan_sip.c:8059 sip_poke_noanswer: Peer '3201' is now UNREACHABLE! Sep 28 15:05:32 NOTICE[8182]: chan_sip.c:6672 handle_response: Peer '3201' is now REACHABLE! Sep 28 15:06:23 NOTICE[8182]: chan_sip.c:8059 sip_poke_noanswer: Peer '4881' is now UNREACHABLE! Sep 28 15:06:33 NOTICE[8182]: chan_sip.c:6672 handle_response: Peer '4881' is now REACHABLE!

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?
