Hi,

I have configured 1000 nos. of Cisco IP phone in my network with CUCM 8.6 and 2951 voice gateway router. If someone wants to communicate with rest of world then all call flow going through reliance PRI Line.

I have 12 CO port (FXO Port) in my voice gateway router. I have connected MTNL PSTN line in FXO 0/0/0 port (number of PSTN line is 26531895).

I want to configure my one cp3905 phone with the FXO.

Mansion Cisco phone has configured with 5050 extension in line one and All call going through reliance PRI line.  I want to configure second line with extension 1895 which calls are routing through PSTN line.

Kindly help me for appropriate configuration.

Please find the attached diagram for your reference.

Regards,

Manas Ranjan Behera

Hi,

I assume that your voice gateway is H323. also assume using 9 as an access code to pstn. simply you need to configure 2 dial-peers at minimum, one of inbound dial-peer and the other for outbound. also you need to create css , route pattern, and route pattern. you need to differntiate the FXO call by prefix 99.

voice translation-rule 1

  rule 1 /^99\(.*\)/ /\1/

voice translation-profile out

  translate called 1

dial-peer voice 1 pots

   incoming called-number .

   direct-inward-dial

   port 0/0/0

dial-peer voice 10 pots

   destination-pattern 99T

   voice translatin-profile outgoing out

   forward-digits all

   port 0/0/0

HTH
