   output attenuation 0
   station-id name 2300090
   voice-port 0/2/0:1
   output attenuation 0
   station-id name 2300091
   voice-port 0/2/0:2
   output attenuation 0
   station-id name 2300092
3. Configure dial peers:
   dial-peer voice 2300090 pots
   destination-pattern 6...
   supplementary-service pass-through
   port 0/2/0:0

   supplementary-service pass-through
   port 0/2/0:1
   forward-digits all
   dial-peer voice 2300092 pots
   destination-pattern 6...
   supplementary-service pass-through
   port 0/2/0:2
   forward-digits all
   dial-peer voice 8800 voip
   service session
   destination-pattern 8800
   voice-class codec 4
   session protocol sipv2
   session target ipv4:192.168.50.137
   dtmf-relay rtp-nte
   supplementary-service pass-through

End

   destination-pattern 6...
   supplementary-service pass-through
   port 0/2/0:2
   forward-digits all
   dial-peer voice 8800 voip
   service session
   destination-pattern 8800
   voice-class codec 4
   session protocol sipv2
