I connected the DSC directly to a dedicated VOIP ATA. I did not want the DSC seizing my phone line and for $40 the extra ATA isolates any problems. If I needed to tweak the DSC ATA, I did not have to change my house phone ATA.
I had some problems initially with the useless Cisco SPA112, but have not had any problems with the Obi100.
(Disclaimer: I assume all risks in using VOIP for my alarm system. Thanks to everyone that is worried about my well being.)

It is very easy, at least for DSC, to use a RJ45 straight coupler to connect directly to the ATA with a short length of RJ11 cable.
This creates a dedicated configuration without having to play with any house wiring or the RJ31X and gives the alarm system its own "phone line".

I went with Freephoneline way since no monthly cost. I tried FPL + Obi200 device and it works just fine too. Search RFD if you want know more obi200 and Freephoneline . There are thousands of posts.
You can make the alarm system work first and switch internet after.

Willyburan is using Callcentric (another popular VoIP service provider) with an OBi110
c-ditty is using voip.ms with a Linksys PAP2T
But using VoIP may be less reliable than using a landline for an alarm monitoring service, except you should take note of what Pianoguy mentions below.
Setting up a VoIP service with alarm systems is not especially easy for everyone. So, if you're going to attempt this yourself, don't except guaranteed success.

AcroVoice offers support for alarm systems, and they will preconfigure your device so that it is ready to go as soon as you receive it. If you want to DIY your VoIP setup, the OBi200 and OBi202 ATAs allow you to configure a fixed jitter buffer, which is crucial for reliable data transmission. Look in the admin guide for $NOJI1 and also $NOEC1.

Instead, why not buy a system that connects to the monitoring station via cell, and perhaps also via IP so you can monitor it from your phone?
If you have a smartphone, this device will allow you to monitor your alarm with it. No fees beyond equipment purchase and installation:
You can receive a text message when your alarm trips, and there are no monthly fees. The downside is no police dispatch, but (at least in Vancouver) it's slow enough that there's not a great deal of value there.
It should also be noted that many alarm systems have batteries. So if there's a really long power outage, your alarm system may not work either, depending on the system.
