I am having difficulties getting International Calls to go through. Does anyone have any clue to what would be preventing me from making those calls?

Hi, for your DP 5, the proper config config is wihtout any forward-digits command, and prefix 011 instead.
Another little know technique is:
destination-pattern 9[0][0][1].......T
this way, no prefix command is needed.
Hope this elps, please rate post if it does!

telcos and they're requests hehe
weird thing, i've configured that but if i strip the 011 i at least set the call as international but if that's what the telco expects let's give them that
drop the prefix command from the dial-peer and if you're using CUCM change the type under the GW or endpoint config to send them unknown and try again

p.bevilacqua -
Thank you so much for the fast response. If I am reading your reply correctly my DP 5 should look like this?
dial-peer voice 5 pots
description International
destination-pattern 9011T
port 0/2/0:23
prefix 011
04-07-2008 01:42 PM
Yes. Only, it is always better to place at least 6-8 dots before the T to enforce a reasonable minimum lenght in the number.
04-07-2008 04:31 PM
Hey Paolo, i've never thought of using a couple of dots in the international calla dial-peer but guess you're right.
Some extra dots before the T won't hurt =), at least a couple of them for the country code
also as a little extra to your info, Steven when configuring a dial-peer or a route pattern for international calls there is really no way to know how many digits a user is going to dial and since the dial plans in the world are very different configuring a hard number of digits would mean that only countries to which that max N numbers make the whole phone number would be reachable.
in your initial scenario a call to a country in which i need 16 digits to call would fail.

Yes, in fact an even better DP for international would be:
destination-pattern 9011[2-9].....T
I personally like to enforce dialplans in the gateway to minimize misdialed calls.

After hcanging the dial-peer check if you are in fact sending a q.931 setup message or not by debugging debug isdn q931
You may try to tweak the numplan or num type for isdn called party

Where is that you configured type international ? in the CM, or do you have a translation profile or isdn map address perhaps, please remove that, is not supposed to be there.
04-08-2008 09:49 AM
It is configured in the CM. Do I need to set it to "unknown"?
04-08-2008 10:01 AM
do you know what is your telco expecting for international calls??
what digits are they expecting?
what numbering plan?
this way you can match those requirements

I really appreciate all the help .... I just spoke to the Telco and they are telling me they needing me to set the switch type to UNKNOWN, and that I need to strip off the 011 before sending them the digits.
That doesnt make sense to me, how will the telco's dms switch no what to do with the call if I strip the 011 off?
04-08-2008 10:13 AM
Yes please.

The logic of not needing prefix when type is international makes perfects sense.
Then you have at least 10 different places in CM and router where you could play with numbers and plan/type, all of which again do make sense if you know what are you doing.
But at the end of the day I understand that with all these things perfectly under control for the experienced, someone at the first installation (and 2nd, 3rd possibly) will get lost in no time.
