Changing call type from Unknown to International

[fitzgerald.d]

I have inherited a CME system that I'm not very familiar with and looking for some help. I have been asked to make international calling work on this phone system as apparently it never has before. After setting up an apprpriate dial-peer and consulting with the TELCO I've run into one last problem preventing this from working.

This is my dial peer:

dial-peer voice 40 pots

description *** Outbound International Dial Peer ***

destination-pattern 9011T

port 0/0/0:23

prefix 011

Currently if I send all the digits for an international call, (ie. 01139XXXXXXXXXX) the call is tagged as an "International" call as per the Q931 debug below:

Channel ID i = 0xA9838A

                Exclusive, Channel 10

        Called Party Number i = 0x91, '01139XXXXXXXXXX'

                Plan:ISDN, Type:International

Dec  1 14:10:52.237 MDT: ISDN Se0/0/0:23 Q931: RX <- CALL_PROC pd = 8  callref = 0x825F

If i strip the "011" from the call and only send eveything after that, the call is tagged as "Unknown" as per the debug below:

Channel ID i = 0xA9838A

                Exclusive, Channel 10

        Called Party Number i = 0x80, '39XXXXXXXXXX'

                Plan:Unknown, Type:Unknown

Dec  1 14:07:35.987 MDT: ISDN Se0/0/0:23 Q931: RX <- CALL_PROC pd = 8  callref = 0x825D

The TELCO has informed me that for this to work I must send the prefix 011 and have the call marked as "Unknown", OR send it without the 011 prefix and have it marked as "International". I've tried quite a lot of different things and just can't seem to get this to work.

Any advice would be appreciated. Thank you

Hi Duncan.

You can set the ISDN plan type using number translation rules,

example:

voice translation-rule 1001

rule 1 /^9011\(.+\)/ /\1/ type any international plan any isdn

!

voice translation-profile out_isdn_international

translate called 1001

!

TDM_Gateway#test voice translation-rule 1001 9011123456789

Matched with rule 1

Original number: 9011123456789   Translated number: 123456789

Original number type: none      Translated number type: international

Original number plan: none      Translated number plan: isdn

TDM_Gateway#

So you would then have:

dial-peer voice 40 pots

description *** Outbound International Dial Peer ***

translation-profile outgoing out_isdn_international

destination-pattern 9011T

port 0/0/0:23

prefix 011 ! this is probably wrong unless you're going from pots to pots, if going from voip to pots - get rid

! i.e.

no prefix 011

Hi Adam,

Thank you for the advice.

I've made the configuration changes as per your post, my dial-peer is now:

dial-peer voice 40 pots

description *** Outbound International Dial Peer ***

translation-profile outgoing out_isdn_international

destination-pattern 9011T

port 0/0/0:23

!

And the test was successful:

RTR01#test voice translation-rule 1001 901139347345XXXX

Matched with rule 1

Original number: 901139347345XXXX       Translated number: 39347345XXXX

Original number type: none      Translated number type: international

Original number plan: none      Translated number plan: isdn

However when I ran a csim the call still failed, and the debug shows the call still marked as unknown:

Channel ID i = 0xA9838A

                Exclusive, Channel 10

        Called Party Number i = 0x80, '39347345XXXX'

                Plan:Unknown, Type:Unknown

Dec  1 15:16:01.284 MDT: ISDN Se0/0/0:23 Q931: RX <- CALL_PROC pd = 8  callref = 0x8265

        Channel ID i = 0xA9838A

                Exclusive, Channel 10

Dec  1 15:16:01.284 MDT: ISDN Se0/0/0:23 Q931: RX <- PROGRESS pd = 8  callref = 0x8265

        Cause i = 0xC284 - Vacant code or prefix digit not dialed

        Progress Ind i = 0x8288 - In-band info or appropriate now available

Dec  1 15:16:21.289 MDT: ISDN Se0/0/0:23 Q931: TX -> DISCONNECT pd = 8  callref = 0x0265

Did I miss something? Is there a level of debug I can run to see if the rule is being applied properly.

Thank you
