Cisco 7970 and Asterisk config help

[pga57]

Hello All,

I try to use a cisco 7970 on LinuxMCE 7.10.
For the moment, I have the hability to receice external calls but it is not possible to dial external number.
I've look at a lot of config files but it is really hard for me to determine the wrong or missing parameters.

When I look on the asterisk log, I have some errors:

[Mar 21 15:25:15] VERBOSE[7949] logger.c:     -- SCCP: Accepted connection from 192.168.80.227

[Mar 21 15:25:22] WARNING[7909] chan_sip.c: Bad request protocol Packet

Can those explain the problem I have ?
How can I correct them ?

Thank's for your help.

I've resolve my external calls problem.
My outbound route was not correct.

I have allways the "bad request protocol packet" error in the asterisk log.

What can be the reason ?
