I have recently installed an SPA9000 & SPA400. I do not have an ITSP, I simply have multiple PSTN lines connected to the SPA400 on three separate phone numbers (and no hunt groups from the telco).
What I would like to do is configure the call routing so that if a call comes in on a particular line, it is routed to a particular extension. In the event that there is no answer at that extension, I would then like for the call to end up in that extension's SPA400 voicemail box. Also note that I have shared line appearences configured for two of the extensions (the first two). For example:
I have attempted various contact list call routing rules, but I cannot seem to get the desired result.
Has anyone else setup this kind of configuration? If you'd show me an example call routing rule, I'd appreciate it.
In your SPA9000 Contact List you should do this, to route specific lines to specific extensions. (Note that the FXO_Port_ID_n names are defaults in the SPA400)
FXO_Port_ID_1:101 | FXO_Port_ID_2:102 | FXO_Port_ID_3:104
Then in the each phone, you need to set the call forward no answer to vm. (voice mail)
Of course, this is the way it's supposed to work, but there are so many bugs in the SPA400/9000 you might need to find a hacked-up work-around, or you might even need to install an older version of the SPA400 firmware.
