Asterisk Google Voice PSTN console dialing problem


   I am new to asterisk My objective is calling to PSTN ( US Phone) using asterisk-Google voice and to play a audio file.I followed this document ([ ... ing+Google]( ) and configured google voice and google talk integeration with asterisk ...I did not configure sip.conf part because i just want to do a auto dialout with asterisk so my extension.conf looked like this

exten => s,1,Answer()
exten => s,n,Wait(1)
exten => s,n,SendDTMF(1)
exten => s,n,Playback(hello-world)

;; dial out

exten => _1XXXXXXXXXX,1,Dial(gtalk/asterisk/+${EXTEN}

Installation was smooth jabber got connected with my gmail. to test inbound I placed a call to google voice number from my cell phone the call was picked up by asterisk and a hello world wave file played. so inbound call is working perfectly.

But when i placed a outbound call (to my cell phone) using the CLI command

CLI> console dial 12********7

I get the call in my cell phone but when i attend the call i hear calling tone , my cell phone is calling some other number to connect or may be conference in i am not sure and it is going on ringing…but my CLI console shows call attended…but i continue to hear calling tone in my cell phone…


Since i don’t have any audio driver so i got a warning message in my console unable to access in my console /dev/dsp but i did touch /dev/dsp then i did not get the warning but still my problem did not resolve

My server is centos 6.2 32 bit Linux server with Asterisk

pl let me know if i am doing anything wrong here I would really really appreciate any help…

Thanks guys…
