Need help on IOS VG(3640) config details

I am implementing IP Telephony network , wherein i have Cisco 3640 with fxo ports as voice gateway.The ccm version is 3.0.1 which is without auto attendant.so a manual call attendant(ip phone) is required in betweem ccm and vg. Now as soon as the call comes in from pstn , the fxo port should switch that call to manual call attendant(ip phone), what would be the config for it. Dial-peer voip has to be defined with session target as the ip add of manual call attendanti.e the ip phone but i am not sure what would what i have to define in dial-peer pots ?

First you should have the voip dial-peer configured to point at the Ip address of the CM itself.

Then set the voice port to do a PLAR connection to the attendant number.

ex.

dial-peer voice 1 voip

destination-pattern 3... (3... assumes your cm extension begin with 3 and are four digits long)

voce-port 1/1

destination-pattern 2xxx

connection plar 3123 (assumes attendant extension is 3123.

plar-opx might be a better option since then the VoIP-GW will not "answer" the call until the AA actually answers it....this way the customer (external if non 1-800#, or internal if 1-800#) is not billed until the call is actually answered. "plar-opx" is only supported on FXO ports, and has been available since the 12.0(7)XK release.

dial-peer voice 1 voip

destination-pattern 3... (3... assumes your cm extension begin with 3 and are four digits long)

codec g711u

session target ipv4:x.x.x.x (where x.x.x.x is the AA)

!

voice-port 1/1

destination-pattern 2xxx

connection plar-opx 3123 (assumes attendant extension is 3123.
