Is it possible to use the SPA9000 mated with the SPA400 and only use 4 analog phone lines without a VOIP provider?
I want to get a new phone system, we are not ready to go VOIP yet, however I want something that will allow me to go this way in the future. The SPA400 has 4 FXO ports on it which can be used for analog lines. What I dont know yet is if I can use the features of the SPA9000 (Extensions, paging, call transfers, etc) and the SPA400 (Voicemail, analog lines) together and have the phone system route the analog lines to my SPA942 phones.
ie: Call comes in on analog line 1 (555-1111), it gets sent to phone extension 100
call comes in on analog line 2 (555-2222), it gets sent to phone extension 102
Extension 103 wants to make a call, it uses analog line 3 (555-3333)
1 year from now, we decide to move to VOIP, get a supplier for that which links directly into the SPA9000 and we drop the 4 analog lines but still use the SPA400 for our voicemail.
I am concerned if I buy the gear, that it will be mandatory to have a VOIP provider in order to function.
Your help is appreciated.
Short answer: Yes
You can deploy a SPA9000 Voice System with any of the following:
- 1 to 4 SPA400s [up to 3 for 12 FXO ports and 4th one for vmail]
- 1 to 4 ITSPs allows you to use 4 different ITSPs if you'd like
- Any mix of ITSPs and SPA400s
Inbound calls can be routed based on many factors, as can outbound calls.
The SPA9000 setup Wizard helps you easily deploy a SPA9000 with 0 to 1 ITSPs and 0-4 SPA400s.
