Hi,

I am trying to bridge asterisk voip users with pstn conference.  
I set exten 500 for the conference and:

[custom-eop]

exten =\> 555,1,MeetMeCount(500|count)  
exten =\> 555,2,Gotoif,$[${count} = 0]?6  
exten =\> 555,3,Meetme,500|cxApMs  
exten =\> 555,4,Playback,goodbye  
exten =\> 555,5,Hangup  
exten =\> 555,6,Goto(from-internal-custom,556,1)  
exten =\> 555,7,hangup

exten =\> 556,1,System(/bin/cp /etc/asterisk/1-test /var/spool/asterisk/outgoing/)  
exten =\> 556,2,goto(from-internal-custom,555,3)

exten =\> 557,1,Directory(default)

exten =\> 558,1,System(/usr/sbin/asterisk -rx “meetme kick 500 all”)

exten =\> 560,1,Meetme,500|xApMsc|1234  
exten =\> 560,2,Hangup

exten =\> 3000,1,Goto(ivr-4,s,1)

Basically user dials in 555.  
If this is first user the asterisk executes  
exten =\> 556,1,System(/bin/cp /etc/asterisk/1-test /var/spool/asterisk/outgoing/)

This file looks like this:

Channel: ZAP/4/number  
Callerid: 1  
MaxRetries: 1  
RetryTime: 60  
WaitTime: 30  
Context: from-internal-custom  
Extension: 560  
Priority: 1

New user that dials in gets to the conference diffecty where both  
voip and pstn channels are bridged.

The problems with this setup:  
1.when all users disconect, the pstn channel is still up,  
2.users cannot send dtmf codes to the pstn channel

Any ideas how this could be improved?

Thanks

Bart
