Solved: CLI And TON in h323 gateway

sivakumar.kvp · ‎02-25-2010

Hi ,

The problem here is when i call US numbers they see 'unknown number' as calling party.

My setuplooks like this : Cisco Phone -> CUCM 7.0 -> h323 gateway(3845) -> PRI line

When i debug outbound calls , i see this below.

Calling Number=2009,(Calling Name=)(TON=Unknown, NPI=ISDN, Screening=Not Screened, Presentation=Allowed),

Would be greatful if you guys guide me how to configure CLI format as International and TON/ANT as 1 in h323 gateway else any other configuration needs to be done to get CLI on called party phones.

Appreciate your quick response.

As indicated above, it is a telco problem and you cannot do anything about it.

The reason is almost every international call goes to the user as unknown number.

The fact itself that some calls show the number clearly indicates that it depends by the route used by telco for the US, that can be different from a call to another.

If when you call locally they see your number, but when calling the US they do not see it, that is a telco problem and you cannot do anything about it.

It is very common for international connections to loose the calling number.

They are incorrect.

Changing anything relating to the calling number is conceptually wrong and will have no effect.

Hi,

oh ;

But is there any way to get CLI presented on called party phones ?

The reason is almost every international call goes to the user as unknown number.

Thank you so much but again am asking the same question since iam in a bad situation to fix this
