Hi there
That answer includes using tcpdump to check for SIP packets and examine the
register packet. At this point you have no SIP packets coming from your
phone so you are not upto that stage yet.
You need to know why there are no SIP packets coming. My guess is your
config files have a typo in them. You can modify the ones I sent to see if
they work for you. You do need to validate your configs. I recommend telnet
to the phone, and checking the display settings to see if it has picked up
the settings. Equally check the phone logs. It will tell you which files
have errors.
Until you get the settings loaded correctly nothing else will matter
Enjoy your break. If you want to use Voip you should definitely spend some
time to learn tcpdump. If you want to use Cisco you need to be able to
understand the configs yourself and get as much info from the phone as
possible. Not hard but it takes a little bit of time.
Cheers Duncan
