I know networking fairly well, and am familiar with Cisco equipment for that. I'm okay with traditional key systems.
I'd like to use Cisco call manager express with a SIP trunking provider, and "key system" functionality with Cisco phones.
In case that doesn't get the idea across: let's say I have a publicly dialable phone number--let's say it's 919-477-5000 (this is a real number, but isn't mine), that's hosted by Vitelity or Flowroute. Or even Google Voice.
I'd like CME to register with that service over the Internet, and have several (Cisco) phones colocated with the router. I want the phones to have extensions like 301, 302, etc., and to have selected phones ring when someone calls my public number, and to be able to dial 9 plus a PSTN number, and have the outbound call do to Vitelity/Flowroute/Google...
I've searched for example configurations, and haven't found any. I don't know if this is because it's not possible, or maybe just because people who are messing around with SIP PSTN connections aren't typically the same people using call manager. The Cisco examples tend to be with conventional (expensive, wired) trunks, and the SIP examples tend to be with 'free' VoIP systems like Asterisk, FreePBX, etc.
This is for fun and learning, I don't intend to use it in a commercial or life-safety application.
If anyone has either a working config they'd share, or a pointer to a write-up someone has already done, I'd appreciate it.
Thanks,
Heath
