Dear Sir;
When SPA phones are behind a SPA9000, SPA9000 controls their dial plan by the parameter [SIP] Phone Dial Plan located in the SPA9000 configuration.
Basically dial plan is managed on SPA9000 in a two stage process:
- 1st dial plan is the Phone dial plan - It controls digit manipulation and interdigit timers at phone level.
- 2nd is the call routing rule + Line dial plan - Call routing rule performs at name indicates, call routing based on number prefix. Then call is passed to the SPA9000 Line (1-4). Each line has a dial plan for digit manipulation (typically to remove the steering digit if any).
If you want to manipulate the phone dial plan, go to SPA9000 [SIP] Phone Dial plan.

Alberto
