E1 PRI Multiple

Hello,

I have 4 E1 Pri links with different DID terminating on 2 no'sVoice Gateway. How I should plan on CUCM 8.6 so that the users of specific DID should flow from his E1 PRI link.

Please explain

Thanks

Re: E1 PRI Multiple

Ok. Let's try to be a little bit clearer :)
Let's assume you have a user John with extension 1000 and he wants to appear as 1234561000 to outside user phone.
Assume that did 123456XXXX is provided from the PRI link attached on port 0/0/0 of your VG.
Make sure you have correcly added your vg on Cucm
-Configure a partition eg Out_John
-Configure a Calling Search Space Eg CSS_Out_John end include previously configured partition and all other partition needed to reach other internal Extension and/or other service numbers (eg voicemail)
- Configure a route pattern such as 9.!
-on called party transformation mask select discard ditgits pre-dot option
- on prefix digit insert a prefix such as 1070
- select your h323 gateway and click add

-----on your vg------
configure a dialpeer as follows.

dial-peer voice 10 pots
destination-pattern 1070T
port 0/0/0:15


You shold use the above example for each user that need to use a particula DID changing each time partition,css, prefix and so on

Hi Jack.
If you see at my previous post, the tranlation rule 2 is defined as called not calling on translation profile CALLID

Hi Jack.

voice translation-profile DID

Modify the translation profile as reported above, and you'll see it working.

Hi Jack.

From CUCM side you can work with Partition-CSS-Route List to call outside matchig the right VG with the right PRI and applying prefix that would be matched from the VG.

On VG , configuring dial-peers matching the previously configured prefix.

This is only one of different solutions.

It all depends on what protocol you'll use and you're not mentioning that.

Dear

I will use H.323

Then as Carlo mentioned, it all comes down to prefixes and matching them in the dial-peers

E1 PRI Multiple

Hello,

I didnt understood the professional words from the expert, can you you elaborate more in steps.

Thanks

Cisco Employee

E1 PRI Multiple

RP 9.@

PT customerA

prefix 12345

dial-peer voice 100 pots

destination-pattern 12345.T

port 0/3/0:15

And so on to match calls on each E1

Segregate via CSS/partitions in CUCM, add prefix, then match that prefix with a dial-peer tied to a port on ISR.

This has been discussed many times before, you can do a quick search to find a lot more info.

Re: E1 PRI Multiple

Hello Carlo,

Thank you very much for elaboratng more. I will just confrm what I understood from your above words.

For example PRI-A

  • PRI-A users will be in line partition of PRI-A
  • PRI-A users will have a CSS include partition PRI-A,PRI-B,PRI-C,PRI-A-GSM,PRI-A-National
  • Configure a route pattern for ex GSM 9.9XXXXXXX and select partition PRI-A-GSM (country runs on 8 digit plan)
  • On called party transformation mask select discard ditgits pre-dot option
  • On prefix digit insert a prefix such as 11
  • Select your h323 gateway and click add

Now the VG will receive 10 digits, 8 digits the actual which user is dialling and we added 2 more (11) for segragating from other PRI's, suppose my block is for PRI-A is 22222000 to 22222199 then how the translation profiles will be created ?? ITSP is accepting 8 digits and forwarding towards me 8 digits.

Thanks

Re: E1 PRI Multiple

Hi.
In your vg you wil configure a dial peer pots as
dial-peer voice 10 pots
destination-pattern 11T (where 11 is the prefix applied on route pattern on cucm)
port 0/0/0:15

by default vg discards declared digits and , in your case, 11 would be discarded and only 8 digits would be sent to your provider without applying any translation

Re: E1 PRI Multiple

Thanks Carlo,

Sorry Carlo, I made a mistake i will have a 4 digit extension on phones so the VG will receive  6 dgits (112001) how i shld configure the translation profile ?? I want to remove 11 before going to ITSP

by default vg discards declared digits and , in your case, 11 would be discarded

Could you explain me why 11 would be discarded ?? if it is dot .T then everthing will be discarded before T , but if i put 11T then 11 will go with extension 112001

dial-peer voice 4 pots

translation-profile outgoing CALLID

destination-pattern .T

port 0/0/0:15

forward-digits all

The Below translation profile.

voice translation-rule 1

rule 1 /^2222\(2...\)$/ /\1/

!

voice translation-rule 2

rule 1 /^\(112...\)$/ /2222\1/ ----- I wanna remove 11 before going to ITSP

!

!

voice translation-profile CALLID

translate calling 2

!

voice translation-profile DID

translate called 1

voice-port 0/0/0:15
translation-profile incoming DID

Thanks

Re: E1 PRI Multiple

Hi Jack.
If you want a user to display itself with a particular number mapped on a particular pri link , you have to configure a dialpeer that matches the prefix configureg on cucm and sets the exit the exact voice port. that's why in your case a dial-peer pots with a destination-pattern .T will not be useful.
You should follow what me and Jaime suggested you on our previous posts.

Re: E1 PRI Multiple

Dear Carlo,

I am a beginner for CVOICE, so forgive my silly question.

You'll are experts definately i will follow you, I am asking just to be clear my doubts.

I have a 4 digit extension so this mean ITSP will recive from me 4 digit,  but they are expecting from me 8 digit so how can i translate.

Thanks

Please reply

Re: E1 PRI Multiple

Hi Jack don't worry ;)
Regarding you calling number...
if the DID assigned from the provider is 2222XXXX on port 0/0/0 and your extension is 1000 selecting voice port 0/0/0 by configuring dial peer as suggested, the you will be displayed as 22221000 without any translation.
For incoming call your translation are correct.
you should apply it on incoming dialpeer.

eg.

dial-peer voice 100 pots
incoming called number 2222....
translation-profile incomig DID
as you correctly assumed .

You are new but your are doing great!
:)

Re: E1 PRI Multiple

Dear Carlo,

Thanks for the reply and being patients to reply me questions

May be i am not understanding but pls correct me,

  • Suppose my extension 2001 when i dial a number 9.9XXXXXXX you told me to do discard digit predot and to add the prefix digit 11 the call reaches the VG with calling number 112001 and the Called number 9XXXXXXX the VG match a dial-peer with destination pattern 11T which will explicitly discard the digit before T and forward the call of called number 9XXXXXXX and the calling number 2001, ITSP will not accept the 4 digit they told me that they accept full DID that means 22222001. so for this reason i must need translation profile.

  • I should keep Each PRI blocks in different device pool or let all the extenson be in default device pool is it a best practice.????

Thanks

No, you're not getting the idea after all the examples and explanations

A) you add the prefix to the CALLED NUMBER, apparently somehow you got to the conclusion you add it to the calling number, no, that's wrong. Drop that idea.

B) it won't discard 11 just because it's before T (or . for that matter), pots dial-peers discard EXACT MATCHES on the destination-pattern

And the above point, is the WHOLE idea behind what you need to do to, make this work.

C) DPs have nothing to do with this, you use CSS and partitions. Specially with H323, in CUCM you configure ONE H323 GW, CUCM has absolutely no idea how the call is going to be routed on the GW, or if it's going to use a T1/E1/FXO/etc. Even with MGCP, you configure ONE MGCP GW, with ALL the endpoints, you cannot separate each PRI on a DP.

Again, this has been discussed many times before on CSC, and searching will provide more examples.

E1 PRI Multiple

Hello

How can I remove the prexis from phone display nd how can I solve the issue of mossed call by adding prefix

E1 PRI Multiple

Hi Jack.

Missed calls are incoming calls which don't need to be prefixed.

What we are working on, is the outside call routing.

When a user calls an outside number using a predefined port (with prefix workaround showed above) he will appear to the remote phone with the root number of selected voice port plus his extension so can be called back in case of no answer.

Re: E1 PRI Multiple

Hello Carlo,

+5 for second reply from top,

I applied your above theory of partitions and CSS  and the calls are going out, but as i told you that i have to add the translation for outgoing call without it will not work and it became true, when i don't put any translation the calls were not going out when i apply translation call started flowing, i think may be you 'll didnt understood me, but anyways i respect your replies as you'll are experts.

Now what i want is the below i will write in steps so it will be more clear.

  • when anybody dial GSM number for ex from PRI-A , on user phone display it shows 1012345678  (10) is the prefix and

          12345678 is the real GSM number. how can i avoid to display (10) prefix

  • when a GSM user call corporate user , the missed call are seen on the phone , when the user wants to dial that missed call from the call history he can't dial becz our dial plan is by pressin 9 for outside calling, so how i can add prefix 9 on the missed call numbers.

Thanks

Re: E1 PRI Multiple

here is the attached

Re: E1 PRI Multiple

Hi Jack.

Let's take your dial-peer 60 as example.

You have

dial-peer voice 60 pots

translation-profile outgoing CALLID

destination-pattern 13T

port 0/0/1:15

in this case user dials external number and 13 prefix is applied

configure what follow

voice translation-rule 13

rule 1 /^13/ //

voice translation-profine CALLID

translate called 13

With above config, user will show only dialed number.

For the second question

voice translation-rule 100

rule 1 /.*/ /9\0/

voice translation-profile DID

translate calling 100

Re: E1 PRI Multiple

Hi Carlo,

mean to say below, i applying configs in the exisitng translation profile as they are already applied on voice port and dial-peer, You can have a look at running config in previous post.

voice translation-rule 1

rule 1 /^4485\(5...\)$/ /\1/

rule 2 /.*/ /9\0/

!

voice translation-rule 2

rule 1 /^\(5...\)$/ /4485\1/

rule 2 /^13/ //

voice translation-profile CALLID

translate calling 2

!

voice translation-profile DID

translate called 1

Thanks

Re: E1 PRI Multiple

Re: E1 PRI Multiple

Dear Carlo,

Sorry my bad didnt noticed

but what abt the DID below configs it is not working, the prefix "9" is not added on the missed calls.

voice translation-rule 1

rule 1 /^4485\(5...\)$/ /\1/

rule 2 /.*/ /9\0/

voice translation-profile DID

translate called 1

Thanks

Re: E1 PRI Multiple

Hi.
This simply add a 9 to calling number so that missed and received calls can be dialed back immediately.
