Hello,

We want to send the "original caller id" out to an end user when diverted from the pbx, using Gamma SIP in the UK.

Currently the system just sends the CLI in the CLI send table.

I have "Recieved CLI forward on Alias" set to Enable, in SIP trunk options but i feel like there is an additional setting to be configured.

SIP trunks are set for peering.

CLI Flexibility is set on the Gamma network

System is 7400 running V5.01

Firewall is third party

Any suggestions would be appreciated.
