US CME to UK CME

I inherited a CME in London and just installed one here in the US. I have extension to extension call working, now I am trying to configure the US CME to be able to make regular calls through the London CME via our VPN. I am looking for an example config to do this.

Thanks.

Re: US CME to UK CME

I'm not sure the dial plan structure is correct, but this should get you started.

US CME

dial-peer voice 1 voip

destination-pattern 90114420........

session target ivp4:2.2.2.2 (UK CME)

codec g711ulaw

UK CME

dial-peer voice 1 voip

incoming called-number 90114420........

codec g711ulaw

dial-peer voice 2 pots

destination-pattern 90114420........

forward-digits 10

port 1/0:23

There are other ways to do this and other options such as using g.729 across the WAN to conserve bandwidth.

Hope this helps.

Thanks now I get a fast busy but I will troubleshoot it from here.

Re: US CME to UK CME

Make sure you have the following command in the UK CME.

voice service voip

allow-connections h323 to h323

Re: US CME to UK CME

If you turn on "debug voip dialpeer" on both gateways, do you see the call hit the correct dial peers?

nothing on the UK side

Re: US CME to UK CME

You have "term mon" on on the UK side, right? Can you ping 172.23.120.1 from the US CME. If you're not seeing anything on the UK side, the call is never reaching that box. Sounds like an IP address/IP connectivity problem.

Re: US CME to UK CME

no I can ping it. Term mon works when I do debug ip icmp

Re: US CME to UK CME

3-digit dialing worked before entering the TEHO config? If so, take this config out and see if it starts working again.

Brandon

Re: US CME to UK CME

I got the 3 digit dialing working again.

Re: US CME to UK CME

Looks like the London debug show a 9011442........ call hitting dial peer 10. Did you renumber your dial peers? Can you post the config for the router?

Re: US CME to UK CME

Remove "destination-pattern 90114420........ " from dial peer 50. After doing this, is it possible to dial 90114420........ from the London office?

Re: US CME to UK CME

So apparently I need to translate 2883 to my london main number of 02078323440 because the London telco doesnt recognize the 4 digit number.

New Member

Re: US CME to UK CME

Hi, don't know if your translation worked or not but one of the ways around this is on the UK end create a voice translation profile that 'translates' your calling US extension to have type and plan unknown.

In the following example assume that the US extensions are in the 1... range:

voice translation-rule 4

rule 1 /1.../ // type any unknown plan unknown unknown

voice translation-profile OUTBOUND

translate calling 4

dial-peer voice $$$ pots

translation-profile outgoing OUTBOUND

This has worked for me in the past when US callers are using TEHO through the UK.

Hope it helps.

Re: US CME to UK CME

Would that go on the UK side

New Member

Re: US CME to UK CME

I tried that and I still get a long deep tone.

Silver

Re: US CME to UK CME

If I`m right from the US you send all the digits to the UK and then the UK translates it?

It seems you have a UK translation which is any number with a type internatuional add prefix 900, or national add 90 so you end up with a number of 900901144..... or 9090...... ???????????????

Also the Dial-peer

dial-peer voice 3 pots

destination-pattern 90114420........

port 0/0/0:15

forward-digits 10

!

will not work either as you are sending 20XXXXXXXX when you should be sendin a prefix of 0

prefix 0

forward-digits 10

so you now send 020XXXXXXX

Depending on where you wish to do the translations my choice is the sending the switch

voice translation-rule 1

rule 1 /^901144\(*\)/ /90\1/ TYPE UNKNOWN INTERNATIONAL PLAN UNKNOWN NATIONAL ISDN

!

This changes the number from US international to UK with national - normally ok if not change it to unknown as well
