Users in London dial 001xxxxxxxxx to call US. The CME config looks like this:

dial-peer voice 1200 voip

destination-pattern 001..........

session target ipv4:

dtmf-relay h245-alphanumeric

codec g711alaw

Then the US CME forwards the call to the PSTN via a Nortel. The config looks like this:

dial-peer voice 1113 pots

destination-pattern 001..........


port 0/0/0:23

forward-digits 10

prefix 9

So I am sending 10 digits and adding a 9 to get the calls out to the PSTN. Does this look correct.

the logic is correct but about the 9 depends on the pstn edge device requerment

good luck

You may need to check the number format you dial from i.e if you call a New York number 0012125551234 then you need to send the 11 digits out of the site 12125551234 but at the moment you only send 10 - 2125551234 and it will fail. - change the forward commend to 11

In addition I think the type of call is important in the US, I`m in the UK so from what I`m aware off also you may need to check the number, plan type incase your local Telco carrier fails the calls due to this - the default dial-peer may send everything out as local plan which is correct if it is a "New York" number but may need to change to long distance if not
