Transition to a new line in dialplan not working :?

Hello.
transition to a new line in dialplan not working :confused:
=-=
Asterisk 1.8.7.0

extensions.conf

Dialplan

[quote]exten => 110,1,Dial(SIP/110,6,m,tT)
exten => t,n,Dial(SIP/gbmarkt/79299917867/,m,)
exten => t,n,Hangup[/quote]

My dial with 1111 to 110.

that the global option is responsible for it in Asterisk 1.8?

I believe the t extension is for incomplete numbers. For timed out dialing you need to check the DIALSTATUS value after the Dial and act accordingly.
