[Asterisk-Users] cisco phones problems

[Carlos Alperin]

How do you power your cisco phones? Are you using any 35xx XL switch?

If that is the case, you need to redo your switch settings enabling QOS. By
default CISCO didn't enable it on their switches made for POE the phones.

It's Funny, no?

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:

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?
