My TSP requires TON set to Unknown and NPI set to E.164 when making calls via ISDN PRI to PSTN. I have a H.323 trunk from CUCM to a Cisco gateway. In the trunk configuration page, at 'Called Numbering Plan', I only have four options: Cisco CallManager, ISDN, National Standard and Unknown. There is no 'E.164' option. I tried all of them, but none of them send the requred NPI, which can be seen in the gateway 'debug voip ccapi inout' output.
Is there a way to configure this on the gateway router?
Any advice is appreciated.
Hard to say without looking at the details.
You can also try this command:
isdn map ....
You can use voice translation rules to set the TON and NPI:
rule 1 // // ?
