ISDN Unallocated/unassigned number

[Ahmed Awida]

Hi Guys,i really need a help with the isdn incoming calls that are not working.

Here are the configurations and the debug q931 outputs :

voice translation-rule 1

rule 1 /2286830/ /132/

rule 2 /2286831/ /300/

rule 3 /2286832/ /104/

Help will be more than appreciated

Few things:

Use "debug voice dialpeer" to ensure proper dial peer is matched

use "debug voice translation" to see if your rule is matched

change destination-pattern to [1,2,3]..

change "incoming called-number ."

Ensure CSS applied to the GW on CUCM has access to the destination

[Ahmed Awida]

Thanks Chris for reply.

I tried what you said but the:

debug voice dialpeer

debug voice translation

They show nothing.

[Chris Deren · Accepted solution]

Did you do "term mon"? 

What about debug isdn q931 is that showing?

Chris

[Ahmed Awida]

I am connected to the console.

yes debug isdn works.

[Chris Deren · Accepted solution]

Can you please post your full config?

The only explanation would be that you are using MGCP GW then which means your dial peers and translations would be irrelevant.

Chris

[Ahmed Awida]

I pressed correct answer by fault.

Yes i am using mgcp.

Do i need to change it and use h323 for example

[Chris Deren]

You have 2 choices:

1. Perform the translations via translation patterns on CUCM

2. convert to H323 or SIP

The first option would be much simpler.

I made the changes on CUCM but also no hope the same message,here are the config on the router related to isdn:

Thanks man for you help

[Chris Deren · Accepted solution]

what changes did you make?

Did you build a translation pattern 2286830 that translates called number to 132? Did you place it in partition that is reachable by the MGCP Port CSS? How many significant digits is that port configured as (should be All)?

Does the TP have proper CSS to reach the 132 extension?

Chris

[Ahmed Awida]

I made everything you mentioned up,but before you offer me to use translation patterns i changed the the siginificant digits to 3 as a last resort and forgot to change it back to all.

Calls are working now.

Thank you so so so much for your help.

I don't know why it didn't come in my mind to use translation patterns on cucm from the begining,but it was so professional from you when you said that i use mgcp and this is the reason.

Your help is so appreciated.

Thanks again Chris.
