SPA9000 and SPA400 used with Analog Only

Answered Question
May 26th, 2009

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.

I have this problem too.

Hi,

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.

Thank you Patrick, the documents helped greatly.  When I called Cisco Small Bus about this I got varying answers including that it cannot be done without a ITSP because the 9000 could not be activated without one.  I see in the documents now that they were mistaken or mis-informed.

One item of confusion, it appears that in order to use the analog lines AND voicemail I need two SPA400's


Is it not possible to run the lines and the VM through one in small deployments.  Looks like I will just need 6 phones, 6VM Boxes and 4 analog lines.

Paul

Hi Paul,

I'm glad you found the documents to be useful.

The issue about analog lines and vmail is that the SPA9000 is designed for a small business or high-end home requiring up to 16 IP phones.

We found that when loaded to the maximum of 16 phones, an ITSP with multiple inbound, outbound, conference calls, AA, MoH, and vmail all happening simultaneously, vmail performance degraded.

Because there is no magic formula, our best practice suggestion is to deploy a SPA400 as a dedicated vmail server if more than 2 PSTN lines are to be used simultaneously.

This is only a recommendation so  you could try one SPA400 for 2 analog lines and vmail and find that everything works perfectly. If not, simply add on an additional SPA400 as a vmail server.

In case you've not seen it, we have a simple, lower-priced solution which we call the Analog Phone IP PBX Solution. This solution utilizes up to two  SPA8000 devices which provide a total of 18 fxs ports for analog phones, faxes, and analog answering machines. We've a very simple wizard that configures up this system in a few minutes. This solution requires an ITSP, but enables small businesses to retain their analog phone investment while switching to lower cost VoIP, without having to train staff on how to use IP phones.
