[Asterisk-Users] Sip trunk groups, possible?

[Bartosz Jozwiak]

Hi Guys,

I have couple of SIP trunks, everyone of them with different IP address.
Is there a way to create some kind of SIP group trunks, like I can do with 
ZAP channels.

With sip I have to do example below, in order to jump to next SIP trunk if 
first one is busy.
Is there another, nicer way to do it?
...
exten => _9[2345]XXXXX,3,Dial(SIP/${EXTEN:1}@FXOQUINTUM1,${DIALTIME})
exten => _9[2345]XXXXX,104,Dial(SIP/${EXTEN:1}@FXOQUINTUM2,${DIALTIME})

With zap trunks it very nice, I just put zap channels in groups:
...
exten => _9[2345]XXXXX,3,Dial(ZAP/G2/${EXTEN:1},${DIALTIME}))
