H323 Gateway T1 PRI call ID problem

[Arturo Alejandro Mendoza Rodriguez]

Hello

I can understadn why I can't modify my call ID in local calls.

Phone A (DN 7156) dial 887-1500, H323 make the call and applied a traslation rule.

Oct 30 13:04:55 EDT: //-1/00FA1AE63403/RXRULE/regxrule_match: No match; number=7156 rule precedence=1

Oct 30 13:04:55 EDT: //-1/00FA1AE63403/RXRULE/sed_subst: Successful substitution; pattern=7156 matchPattern=^7(...$) replacePattern=7697000 replaced pattern=7697000

        Channel ID i = 0xA98381

                Exclusive, Channel 1

        Calling Party Number i = 0x4181, '7697000'

                Plan:ISDN, Type:Subscriber(local)

        Called Party Number i = 0xC1, '8871500'

                Plan:ISDN, Type:Subscriber(local)

In my other gateway recive this...

        Channel ID i = 0xA18387

                Preferred, Channel 7

        Calling Party Number i = 0x0080, '7156'

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '1500'

                Plan:Unknown, Type:Unknown

When I use area code for make the call everything works as I expect.

here is my traslation rules and dial-peer.

voice translation-rule 1020

! this rule is for DID

rule 1 /^70\(..$\)/ /76970\1/ type any subscriber

! this rule is for extensions reached by main number.

rule 2 /^7\(...$\)/ /7697000/ type any subscriber

!

!

voice translation-profile LOCOUT

translate calling 1020

!

!

dial-peer voice 12 pots

trunkgroup AIRESPRING

translation-profile outgoing LOCOUT

destination-pattern 9[2-9][0-9][0-9]....

incoming called-number .

forward-digits 7

any comment will be appreciated

thanks

In the US, you should send ANI as ISDN/national, with 10 digits.

Hi Paolo,

This is the path

phone DN 7156 --> H323 -->  ((PSTN)) --> H323 --> AA 887-1500 both branches are in the same area code 330 and have the same telco.

when DN 7156 dial 91 (330)-887-1500 and local GW send 11 digits the gw at the other end shows.

        Calling Party Number i = 0x0080, '3307697000'

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '1500'

                Plan:Unknown, Type:Unknown

but when DN 7156 dial 9-887-1500 and local GW send 7 digits the gw at the other end shows.

        Calling Party Number i = 0x0080, '7156'

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '1500'

                Plan:Unknown, Type:Unknown

I made the change that you mentioned before but in the other GW shows the DN instead the mask that i did with translation rules.

translaiton rule

rule 2 /^7\(...$\)/ /3307697000/ type any national

local gw shows

        Calling Party Number i = 0x2181, '3307697000'

                Plan:ISDN, Type:National

        Called Party Number i = 0xC1, '8871500'

                Plan:ISDN, Type:Subscriber(local)

In conclusion I just wonder why the telco overrides the translation rule with the DN if I make the call with 7 digits.

thanks

What you're saying is quite confusing. Because if you do not send '7165', there is no way that telco can present that. Maybe check all traces again.

You're rigth.

I did a mistake tracing the call, I forgot the route pattern have a route list with two gateways so the call was rerouted to the back-up gateway and this gateways don't have translation rules to mask DN 7156.
