[Asterisk-Users] DISA multiple calls with single dialup

[Eric]

[DISA-context]     
exten => 204117733,1,DigitTimeout(8)
exten => 204117733,2,ResponseTimeout(15)
exten => 204117733,3,DISA(no-password,default)
exten => 204117733,4,Hangup

We succesfully implement a dialup gateway with the following.

What I now wish to do is to be able to make multiple telephone
calls.  So I would like to terminate an asterisk call with
say a * and then be returned to dialtone.

How would I define that rule?

Thanks.
