Dedicated fxo Ports for each extension

[RUSTOM BILLIMORIA]

Hi,

I am trying to achieve the following scenarios.

i have got three anolog lines running into three fxo ports on a Cisco 2621xm. i have a cucm 6.0 and the cisco 2620xm is connected as a h.323 gateway.

i have 3 extension numbers 1000, 1001 and 1002. i want that

1000 should always dial via fxo 1/0/0

1001 should always dial via fxo 1/0/1

1002 should always dial via fxo 1/1/0

how do i configure both the cucm and gateway to achive the following. the ip phone extensions will always dial out by using 0.

Thanks in advance.

This can be accomplished on the h323 gateway.  You will have to use a combination of voip and pots dialpeers with translations.

To accomplish this, you will need to setup some transation rules that prefix a dialing string in front of the called number going outbound so that it is able to hit the correct dialpeer.  here is a sample of one that I had to do.  Basically, had to setup a system to mimic a key system even though it was centrally managed.  

Outside access code is a "9"  Extension 111 is making the call out and needs to go out line 1 or 0/0/0 FXO.

voice translation-rule 1

rule 1 /^9/ /19/

voice translation-profile Line1

translate called 1

dial-peer voice 900 voip

translation-profile incoming Line1

answer-address 111

voice-class codec 1

no vad

dial-peer voice 2 pots

destination-pattern 19T

translate-outgoing called 1

port 0/0/0

voice-port 0/0/0

echo-cancel coverage 32

playout-delay maximum 200

timing hookflash-out 50

connection plar opx 111

Hope this helps.

Cheers!

Hi Keven,

Thanks so much for your help. The translation profile and explanation worked perfectly. There is just one more question. Out of all the configs you provided me, which ones could I reuse for the other lines. I could not figure that out and created a duplicate copy of the configs. this is what it looks like.

voice translation-rule 1

rule 1 /^0/ /9/

!        

voice translation-rule 2

rule 1 /^0/ /20/

!        

!        

voice translation-profile 1

translate called 1

!        

voice translation-profile 2

translate called 2

dial-peer voice 224145262 voip

translation-profile incoming 1

answer-address 1000

no vad  

!        

dial-peer voice 24145262 pots

destination-pattern 9T

translate-outgoing called 1

port 1/0/0

!        

dial-peer voice 24115262 voip

translation-profile incoming 2

answer-address 1004

no vad  

!        

dial-peer voice 224115262 pots

destination-pattern 20T

translate-outgoing called 2

port 1/0/1

!        

I created two different configs for 2 different extensions. The extension numbers are 1000 to 1010. which of the commands would be common for all extensions. Also if I wanted to share a FXO port between 1002 and 1008, which configs would be common.

Thanks a ton,

Cheers,
