Hi Yousif,

Sure, we use numbers in the 5xxx,6xxx,7xxx and 8xxx all on a "shared" T1-PRI infrastructure :)

Hope this helps!

Hi Huffman,

pleasae find attached a copy from my vgw config and two debug files for two call as below:

1-calling nuber from ext 501"debug-callingnumber 501.txt "

2-calling number from ext 7901 -same range of E1- ""debug-callingnumber 7901.txt

the calls from 5xx not work but when I use 79xx ext it work with me.

is there way to change the Calling nuber to the one from Service provider "79xx" without change the ext "5xx"

If all you DNs are 5xx and the last two match the DID 79xx, then you can create a single voice translation-rule and apply it to a profile for your outgoing pots dial-peer:-

voice translation-rule 2

rule 1 /5/ /79/


voice translation-profile outgoing

translate calling 2


dial-peer voice 1010 pots

translation-profile outgoing outgoing

description local

destination-pattern [24]......

no digit-strip

port 0/0/0:1


This wil translate the 3 digit calling party DN 501 to 7901.

Hope this helps
