I have been looking into VoIP vs regular PBX -- particularly the Asterisk system.

In most scenarios, it seems cheaper to go with Asterisk and SIP/IAX phones and is much more powerful compared to PBX offerings (~20 phones).

On top of this, I get the ability to do VoIP routing, develop a least-cost-per-call routing plan, integrate the system with scripts to provide callers up-to-date automated recordings, etc..

The current PBX is effectively a black box requiring service calls (at $150 or more a pop) for things as simple as adding a new extension, moving an extension, etc.. Things that with Asterisk can happen automatically (moving an extension.. hmm ... anywhere, in the world..) or via a simple webinterface (adding new extensions).

On top of this, is adding voice on the same network as data (saving of infrastructure cost) really adding THAT much overhead? Seems like most codecs are ~13kbps .. doesn't seem like that much of a load on the internal LAN ..

Granted I HAVEN'T done this deployment yet but on this deployment, I was pricing it to be around $425/phone (hardware, asterisk configuration, servers w/PSTN interface cards, switches w/POE, battery backup, etc..) and with the ability to admin remotely, should drasticly reduce on-site calls/issues. I'm definitely interested in hearing of others experiences/rollouts.
