Re: Problem with international calls

kraghavansag · ‎04-08-2009

I am hitting a problem where with one particular carrier, I am not able to send international calls out. I am using a H.323 IOS gateway and the dial peer is standard with prefix 011.

description International Dialing

preference 1

destination-pattern 9011T

port 1/0/0:23

prefix 011

!

When I was troubleshooting, the service provider said their switch does not support 011 from our equipment since they are flagging 011 at their side. they wanted me to strip 011 when sending out through their PRI. I removed 011 from the dial-peer and sent the call. It does not work still. Any idea of what it could be?

Also the career says that they are unable to see any digits coming through if I strip 011 before sending through their crkt. If I add 011, they are able to see the entire digits including 011.

paolo bevilacqua · ‎04-08-2009

try:

interface serial x/y:23

isdn map address . plan unknown type unknown

iptuser55 · ‎04-09-2009

Isn`t the plan, type already set to unknown as per the debug ? Perhaps changing it to International ?

paolo bevilacqua · ‎04-09-2009

It is not set to unknown as it should be:

Called Party Number i = 0x91, '011919710421438'

Plan:ISDN, Type:International

iptuser55 · ‎04-09-2009

Sorry I was looking at the failed call without the 011

paolo bevilacqua · ‎04-09-2009

Without 011, and plan/type isdn/international, the call would succeed. But it is not practical to configure so.

Afragoso2009 · ‎04-09-2009

HI

Try to remove ( if you have ) the "isdn sending-complete" under the BRI interface configurantion

I had the same problem and its Solve to me

kraghavansag · ‎04-09-2009

I applied the command. Now it says I must dial a 1 and the area code followed by number. When I see the debug, I am sending only the international country code followed by the international number without any prefix 011 so that the service provider can add the 011 international flag bit. It still does not seem to work. Any ideas?

I created a new dial-peer for this alone.

You need to send 011. Remove forward-digits command, and use:

destination-pattern 9011........T

prefix 011

or

destination-pattern 9[0][1][1]........T

kraghavansag · ‎04-09-2009

My service provider does not want me to send 011. They say they will add 011. they seem to have some kind of limitation in their telco switch.I use destination pattern 9011T and prefix 011 for all service providers and it works fine. Only this service provider does not seem to accept when I send as 011 followed by international number.

paolo bevilacqua · ‎04-09-2009

Try anyway, and show us the trace if doesn't work.

yxsjwsb · ‎04-09-2009

you might download the pri debugger trial on the pippinsoftware.com site. It makes the process a little easier if you're trying to look real time

Hi kraghavansag,

Did you ever find a resolution to this?

I am currently in a migrate from Avaya to Cisco and will have the same requirement our long distance PRIs.
