Zap Blind Transfer calls to cell phone

I have been trying to blind transfer a call that comes in on a zap channel to my cell phone.

I have scoured through the forums and have found examples (made from peoples heads and in different configurations) but nothing that works

I am in need of a way to take my

Bell canada business line (that can do transfers ) like a person who calls I can flash hook and call another person and then hang up and they are transferred freeing up my phone line.

First I did was head on over to /etc/asterisks

and edited my zapata.conf

I added some things (I dunno if the defaults where fine or not!)

then I added extensions_custom.conf

exten => s,1,Playback(pls-wait-connect-call) ;# does not seem to even play this
exten => s,2,Flash() ;# it defiantly flashes over though
exten => s,3,senddtmf(${ARG1})
exten => s,4,Flash() ;# I thought adding another flash would help
exten => s,5,Hangup()

then I went to the Extensions section and added a Other Custom Device

made the extension 921 and where it said dial I typed in

note sub in the number theNumberIamTryingToGetItToDial
the wwww’s are me figuring that it maybe needs to wait a bit

It just seems no mater how I edit any of the settings when I call it from the outside world and hit 921 I hear it flash hook (Sorry I dunno what else to call this) and I sit there for a bit then it just hangs up on me.

somethings wrong! I want to be able to call in enter the extension 921 have the context custom-call_cell flash over have it send the dtmfs of the number to dial then connect me to the call…

Ugh… is there a easier way to do this.

I am using a sagnoma card

Any Ideas tips please !
