[Asterisk-Users] Using Asterisk to dial a number and then wait to dial the extension

[Andrew Elchuk]

Hi,

I did some searching and haven't found a solution to my problem.  But 
right now we are performing a transition from an old system to a new 
system using asterisk and only a few people are on the new system and 
testing it out.  Anyways, I was wondering if it is possible to dial a 
phone number with asterisk, and then after that callee picks up to dial 
an extension?

In one forum message I found that you could use 'w' in the dial string 
to act as a half second wait.  I tried doing:
exten => 109,1,Dial(ZAP/g1/6525798wwwwww109)
This would dial the other phone system, but would not wait 3 seconds til 
the other system answered and then dial the extension.

I also tried using:
exten => 109,1,Dial(ZAP/g1/6525798|D(109))
But this did the same thing as the above.

Is there another way to dial a number then on the same channel send 3 
more digits after the other party answers?  Thanks.
