[Asterisk-Users] problems with sip

[Andres Baravalle]

Hi,
I'm trying to configure a few service providers in asterisk. I could
configure correctly one only, messagenet.it.

I'm trying to register to sipgate and sipphone, with no success
(cannot register).

I'm inside a (departmental) firewall, not sure of the ports that are
closed, but I can configure the voip providers in eyebeam without
problems.

Any suggestions?

Here is my sip.conf:

[general]
context=default
realm=rosario.dcs.shef.ac.uk
srvlookup=yes
defaultexpirey=480
allow=all

;passwords are changed
register => 1234567:aaaaaaa at sip.messagenet.it:5061/1234567
register => 2234567:aaaaaaa at proxy01.sipphone.com/2234567
register => 3234567:aaaaaaa at sipgate.co.uk:5060/3234567
