[Asterisk-Users] outbound sip calls on asterisk

[James Burke]

hi,

i would like all my calls originating from asterisk users bound for 
external to route to one destination, a session border controller. 
protocol used is sip.

i have edited extensions_custom.conf with:

exten => _.,1,dial(sip/${exten}@x.x.x.x)

would this be correct to send any calls from internal to the x.x.x.x ip?

i get this from the cli:

== Spawn extension (from-external..... then it just times out and dumps 
the calls?

the phone used is a cisco7960 using pos3-07-5-00

any help appreciated... :)
