Where

  y.y.y.z = ip address of gk h323
  y.y.y.v = ip default gateway
  x.x.x.x = ip address of Astersik
  y.y.y.y = ip address of Cisco

And this is the asterisk configuration

sip.conf
[general]
context=default
port=5060
bindaddr=x.x.x.x
srvlookup=yes
videosupport=no

[y.y.y.y]
type=user
host=y.y.y.y
canreinvite=no
context=fromsip
dtmfmode=rfc2833
disallow=all
allow=g729
allow=ulaw
allow=alaw

--------------
 extensions.conf

[fromsip]
exten => _X.,1,Dial(Zap/g2/${EXTEN:2})

I'd be very grateful  for your help on this matter
Best regards,

Jorge
