Any ideas or has someone seen this before?

Thanks.

I have this problem too.

You need to call your provider & ask them what plan & type is required. Then you can change to that using either a translation rule or an isdn map on your PRI interface. I had this same problem where I was able to call certain parts of Europe, but not everywhere. In my case I needed to add

isdn map address 011.* plan isdn type national

which changes all of my International to "type" National.

Have you contacted your carrier about this, if so what did they say? Im thinking that maybe they dont want to see the "011" and just want to see the number with the type marked as "international".

Hi,

Can you try my number..442079011226.

Also send the full debug isdn q931...

We need to know the direction of the disconnect...Is it from your telco or gateway?

I tried the number from here in London and it works okay..01189241400

iptuser55 Thu, 08/28/2008 - 06:59

The number is correct and digit lengt is correct I would like at the type of call you are sending to the Telco perhaps change it to unknown ?

Ayodeji oladipo... Thu, 08/28/2008 - 07:04

Hi,

This is the meaning of the cause code you are experiencing....

Invalid number format...This call happen when you are calling out using a network type number (enterprise) when you should be calling out unknown or national.

Here in the UK we use Unknown..so you may want to change from international to unknown..and try again

mike-greene Thu, 08/28/2008 - 07:38

Thanks,

If this is the second reply sorry...

I have contacted ATT and they said they were able to call the UK from our switch and that the problem was on our router.

Below is all the debug q931 when calling aokanlawon....

I'm new to voice so I'm just getting started...please be patient....where do I change to unknown??? In the dial-peer cor list??

Thanks for the help.

iptuser55 Thu, 08/28/2008 - 07:52

Do you have CCM or express ?if CCM then as a quick test do the following

Locate the gateway you use for the call via the route pattern for 9.11 l, if you are lucky you may have a specific gateway for international calls

2. On the gateway page locate the section -

Call Routing Information - Outbound Calls

3. Look for Called party IE number type and maybe Calling party IE number type and change them to unknown

4. Make a test call again and see if it works. If it does leave it as it is but make test calls on the other possible route patterns in case it effects them

if CME you need to use translations to change the type to unknown on the dial -peer or maybe hard code it directly on the dial-peer for your external calls

mike-greene Thu, 08/28/2008 - 08:18

Thanks,

Here is what my current dial peer looks like after I added the numbering-type unknown...is this the correct command?????

dial-peer voice 34 pots

translation-profile outgoing CALLERID

numbering-type unknown

destination-pattern 9011T

port 0/0/1:23

prefix 011

After the change I still get...

Is this the correct change???

mike-greene Thu, 08/28/2008 - 08:19

Sorry...this is a call manager express router where this is happening.

Kenneth Mohammed Thu, 08/28/2008 - 08:51

Did ATT say whether or not they want the 011 sent to the switch. I know generally if your PRI is on a 5ess switch, then they dont want to see the 011. Try stripping the 011 and leave the call type as international. I did this just the other day and it worked.

voice translation-rule 1

rule 1 /^9011/ // type unknown international

voice translation-profile INTL

translate called 1

voice-port 0/0/1:23

translate outgoing INTL

Try that and see if the call goes thru. I did this for one of my customers who couldnt dial intl and ATT was their provider.

Hope that helped.

mike-greene Thu, 08/28/2008 - 09:32

Thanks for the help,

The q931 debug still shows the call as International after the change...if I did it correctly. Attached is the current voice config on the router. Please keep in mind that all other international calls work fine....only the UK does not.

mike-greene Thu, 08/28/2008 - 09:33

To answer your question ATT did not say anything about 011 being in the call. When I dial France 011 goes out the PRI with no issue.

Kenneth Mohammed Thu, 08/28/2008 - 09:41

Mike, see if you can do some testing with your carrier, and they can setup traps in the switch to see what exactly is being sent out when you make the call, and they should be able to tell you what they need to see coming from the router in order for the call to be successful.

I had an issue like this yesterday, the customer could make all intl calls, except for one number in austria. They could even call other numbers in austria with no issue. When we tested with the telco, the issue ended up being in the long distance carrier's switch and they were able to resolve the issue.

Hope that helped.

Ayodeji oladipo... Thu, 08/28/2008 - 10:25

Can you confirm, what call processing agent you are using.

If you are using Callmanager, the change has to be made in callmanager

Ayodeji oladipo... Thu, 08/28/2008 - 10:40

Mike,

You should try ocnfiguring it under the Virtual serial interfcae...

i.e interface serial 0/0/1:23

mike-greene Thu, 08/28/2008 - 10:53

Thanks,

I don't see a translate command under the virtual interface...which command are you referring to?

Thanks.

Kenneth Mohammed Thu, 08/28/2008 - 11:20

Mike, I think the best way to handle this is to get in touch with ATT, and have them get into the switch while you make the call, so they can see which numbers are being presented, and they can tell you what needs to be sent from the router (011 or no 011) and how it needs to be sent (ie national, international, unknown)

Correct Answer

You need to call your provider & ask them what plan & type is required. Then you can change to that using either a translation rule or an isdn map on your PRI interface. I had this same problem where I was able to call certain parts of Europe, but not everywhere. In my case I needed to add

isdn map address 011.* plan isdn type national

which changes all of my International to "type" National.

mike-greene Thu, 08/28/2008 - 13:21

Thanks !!! I opened a ticket with ATT a couple hours and just before they called I added...

isdn map address 011.* plan isdn type national

to my PRI interface and it works. I learned alittle tech. She said that unknown can be crazy so they don't recommend using that. Using National keeps the 011 on there switch and using International they add 011 to it so you must strip the 011 from the number. She said either way it will work so I left it at national.

Thanks for everyone's help with this!!

Kenneth Mohammed Thu, 08/28/2008 - 14:07

Mike, glad to hear everything worked out for you. I have been encountering these issues with several of my customers as of late, so I have been learning a lot from service providers as far as what different switches expect when making calls.

Also thanks for the nice rating!!

mike-greene Thu, 08/28/2008 - 14:23

No problem on the ratings. I've got to keep you experts happy during my learning curve in my new environment....I'm sure I'll be asking more questions in the future. :)

Thanks again.
