Translating 4-Digit Extension to 10-Digit DID

elemzy

Hi all,
I need help here. I have CUCM 8.0 a call gateway that connects to PSTN.
the PSTN has allocated us 10 digit DID numbers for our external calls while we use 4 digit extentions.
I have been able to map the external 10 digit numbers to individual 4 digit extensions.
When i make external calls, the caller id that gets displayed on destination phone number is the pilot number.
I however want to do a one to one translation from an internal extension number to a DID number.
I did this configuration on the call gateway but caller ID still shows the Pilot number.

voice translation-profile PSTNOUT
translate calling 100

translation-rule 100
Rule 1 9800 0702744059

dial-peer voice 20 pots
description --- OUTBOUND CALLS---
destination-pattern 8T
translation-profile outgoing PSTNOUT
direct-inward-dial
port 0/0/0:15

I ran test on the translation and its okay, but caller id still shows incoming number as the pilot number
OFFICE_2921#test translation-rule 100 9800
The replaced number: 0702744059

You can make a translation rule that will cover your outbound calls. This one I made below. Will grab any number that comes in with a 3 and translate it to the 10 Digit number.

voice translation-rule 2
rule 1 /\(^3...\)/ /737211\1/

voice translation-profile OUTBOUND
translate calling 2

voice-port 0/2/0:23
translation-profile outgoing OUTBOUND


I only do this in SRST. BTW


What I normally do is set the 10 digit DID in CUCM by the number mask and I pass that out of CUCM to the gateway and out to the PSTN.

Hi shodown,
This is what has been done except that the rule is different different. Im only translating for one number while you gave for the whole range of numbers.
This did not work as specified in my initial post.

Maybe i should look at your second option of doing this in the CUCM. Can you shed more light on this?

pitviper

Do a debug ISDN Q931 on the gateway - If you are sending the correct number out, call your carrier – they will sometimes set everything to the lead DID unless you request the ability to send.

Definitely not part of the Cisco "best practices", but I like to do all of my translations, num-expansions, and plan/type settings on the IOS gateways (H.323).

Did debug and i do not see any translation in the output......any suggestion?

try this instead:

voice translation-rule 100
rule 1 /9800/ /0702744059/

pitviper

Also, not sure of your complete config - but the outgoing dial-peer match may not be what you think. Try putting the translation on the voice port:

voice-port 0/0/0:15
translation-profile outgoing PSTNOUT

Hi pitviper, after changing to voice translation-rule 100; rule 1 /9800/ /0702744059/ as suggested. I could see that number is being translated in the debug but calling id on the recipients phone still shows the pilot number. Does this mean my PSTN provider has to do something as suggested above?

As long as the calling number (0702744059) is one that is associated with the PRI – you should be able to send it back out.

I’d give the carrier a call – you can now prove to them that the number is leaving your equipment correctly.

Thanks Pitviper, Ill do just that and revert in the next few days. Its weekend here.

Good luck!

External Phone Number Mask on the DN.

Hi Pitviper,
My provider claims DID number transparency has been enabled, they agreed it wasnt done before now. However, calls still displays pilot number at recipients phone. When i called with the internal phone number (9800) that was translated, my debug shows calling id as the translated number (0702744059) .
but when i try calling a non translated internal number (9850), it shows the internal number as the calling id (9850), i thought it should show the pilot number number instead. Just an observation though.

pitviper

The translation rule above is only for a single DID - You would need to expand the rule, or create another entry for the other DIDs

pitviper

Here’s an example – so let’s say the DID block is 8800-8899, and the full 10 digit numbers are 111.222.8800-111.222.8899

voice translation-rule 2
rule 1 /^88/ /11122288/ type any national plan any isdn

The translated (expanded) calling party number for extension 8810 would be : 111.222.8810
The translated (expanded) calling party number for extension 8811 would be : 111.222.8811
And so on.

Agreed.

Hi Pitviper,
Thanks for your help the last time. Ive been on vacation on resumption i found out the following issues.
i) After the single translation, every other calls from internal number to public numbers shows my internal 4digit extension on the recieving party's phone. This kinda baffles me because i dont expect this numbers to be routable on PSTN (sorry im a routing/switching guy). I also believe all untranslated numbers should use my pilot number instead.
I cannot use your group translation rule cause my internal 4digit extension does not match my providers last 4digit. Providers number range (0702744031-59). Internal number range 9801-50.

ii) My provider asked me to activate "Caller Line Identification Presentation" so i can receive full string of incoming numbers. Is this possible on Cisco Voice Gateway? or this guy is just trying to blow me off?

Your help will be highly appreciated.[FONT=&quot][/FONT]

Can you show us a table that show us the correspondence between the last 4 digit of your service provider and your internal numbers?
This should help creating rules to fix your caller-ID.

elemzy

I have this number range from my provider 0702744030 to 0702744059
I have the following translation rule for incoming.

translation-rule 10
Rule 1 4030 9861
Rule 3 4032 9851
Rule 4 4033 9855
Rule 5 4034 9856
Rule 6 4035 9862
Rule 7 4036 9865
Rule 8 4037 9866
Rule 9 4038 9869
Rule 10 4039 9873
!
!
translation-rule 11
Rule 1 4040 9874
Rule 2 4041 9875
Rule 3 4044 9850
Rule 4 4045 9877
Rule 5 4046 9876
Rule 6 4059 9800
!
!
translation-rule 12
Rule 1 40.. 9861

So when making external calls, i would want to do a reverse translation.

phoeneous

Why are you doing the translation at the gateway? Why not in cucm? Just curious.

demetriusj01

If you are making calls to the external PSTN by default the provider will show the DID number or extension that called out for example if you have a DID of 555-555-1212 assigned to extension 1212 or in your case 0702744030 assigned to 9861 making a call out to the PSTN the provider by default will display to the other end that they are receiving a call from phone number 555-555-1212 or 0702744030 . That is the reason why those call centers that have outbound sales calls usually have a rule like this rule x /^.*/ /999-999-0000/ to mask all their DIDs onto one blanket number . but in your case you may have to create a translation rule for all your internal extension and if that does not work you will have to push hard on your phone provider to fix this .
