I have a 3cx connect to PSTN(ISDN) via Patton 4120 , and Another trunk-sip to Mitel 3300ICP
I have a DDI 024373xx
I have extension 3xx
When i send outogoing call to Provider , Provider need receive correct outbound Caller-ID 024373xx
Than , if i manipulate from extension Outbound Caller ID i can configure 024373xx , but same Caller-Id it is sent towards Trunk-Mitel .
I want manage from extension "Outbound Caller Id" how 3xx for sent correct Caller-Id to Mitel
I want prepend to ISDN 024373xx for correct Caller Id toward Carrier ISDN , without managing internally Patton .
Have you a suggestion ?
