Does * do this internally without having to break out the T with a channel bank?
The clients admin for their VoIP claims it can be done, so I'll have to pull a configuration next time I'm working with them.

The setup is different than a standard * setup though. The T1 from Bell comes directly into the * server where the voice is inserted onto the line and then another T1 card exits for data to the Cisco routers onsite. A simple diagram is below:

Bell --T1--> * server --T1--> Cisco 2600 router --> Ethernet Network

Anybody work with "Add on" VoIP to a traditional PBX? Most of the vendors are offering this as an option for those not ready to make a complete system swap but want or need IP functionality.

Many people struggle work a phone much less run linux or maintain a system, easy as it may be.

For asterisk to be taken seriously by big business (where the $$ is) they must be able to handle the advanced CTI and have a support network.

CK,

Ive done IP trunking with IP Office (and a bunch else too), Avaya made it very easy. The thing I really like about IP office is the scripting out of the box you get with the Attendant and VM. It's really very powerful if you know how to use it. Things I don't like are its POTS FXO's are flaky and simple things are made hard in the GUI- but the usually hard things did seem easy.

Starting to plan for the third. I found it was only slightly more expensive to do a forklift upgrade of the switches than to add a few more extensions and voicemail ports to the old switches.

Asterisk is running on HP DL360's Running Centos 4
Digium PRI cards
Polycom SoundPoint 500, 501, 600, and 601 handsets.

They pretty much sell everything worth buying and prices are competitive. You might be able to shave off a few bucks by shopping around once you figure out what you want. Phones range from $50 to $500+. T1 is $500 to $2500 depending on how many ports and if you want hardware echo cancellation.

When I was shopping for a system, I found I could put together a nice * system for less than half of a crappy ho-hum consumer grade PBX.
A major plus is direct VoIP termination on the * server. I don't know of too many proprietary systems that even offer it, let alone at a reasonable price.
The most expensive part would be the T1 card for *, but they still are not as much as what they cost for proprietary phone systems.
I hate to say it, but I agree that proprietary phone systems will soon be novelty "remember when" items. That's why I'm trying to learn as much about * as fast as I can. I believe my lively hood is going to depend on IP telephony in the next few years.

Ok, tech helped with initial autoattendant call flow setup.

Actually, my single most expensive piece of hardware was the call processor. Half of it's cost was the 30 channel voice compression module and the T1 PRI interface. Voicemail is on standard P4 (running XP Pro) and communicates with the CP via IP (no propietary cards or interfaces). The phones are using H.232 or SIP (latest firmware) and should provide at least base feature portability.

I would assume with Asterisk you still need an interface for PSTN connectivity unless you go IP trunking.

What is your cost estimate for IP hardphones? I am finding that at the top end, they are not much different from propietary digital sets.

Asterisk can probably do all that for $10-20k and no need to deal with high priced Telecom techs. If you have in house IT people who know Linux then your good to go. That is one of the biggest advantages IMHO. If your voicemail card fries on a proprietary system your looking at proprietary pricing to replace the part (sometimes your looking at $2000 just for those proprietary flash cards. In Asterisk it could be as simple as getting another hard drive as Best Buy or wherever.

You are right though, a lot of the cost depends on the phones when your talking about that many. That is another advantage of Asterisk. You are not tied to one vendors phones and proprietary interface. With Asterisk everything is based on the SIP open standard so you have all sorts of options depending on the price vs features required.

I don't have a magical crystal ball but everyone seems to think that proprietary phone systems will go the way of the dinosaur within the next few years. They are pretty much all but dead and buried for high end systems from what I am reading. Everything coming out now seems to just be a glorified server with with a brand name stuck on it and running Asterisk or some customized version of it.]]> http://www.dslreports.com/forum/remark,14854429 Mon, 21 Nov 2005 17:07:37 EDT Re: [Equipment] VOIP PBX Systems - what are you running? http://www.dslreports.com/forum/remark,14852862 CKizer :

I don't know what you paid for that beast but I'm guessing an Asterisk solution can do a lot more for a LOT less.
Let's say around $50K with most of the money in IP hardphones.

If you have experience in implementing an Asterisk solution, tell us about it.

most folks in this forum are consumer users .... you're obviously speaking about a VOIP PBX using a Bell supplied PRI T1 which is totally different than consumer VOIP. be patient for replies...
Totally different. Not at all (I use Vonage at home). Same protocols, same codecs, same connectivity. I just control both ends of the IP link as well as the connection to the PSTN.

There have to be one or two Cisco, 3-Com, Avaya, or other VOIP PBX administrators floating around the forum ;)

Avaya IP Office 412
ISDN PRI Trunk Interface
Voice Compression Module (VCM) 30
8 port analog expansion module
Avaya 4620SW IP Voice Terminals (91 on line)
Avaya Voice Mail Pro

The system has been in operation for almost a year. I just updated the system to the new 3.1 software and everything appears to be working better than ever. The PRI trunk is awesome. 23 two way channels, Caller ID (including name delivery), and effortless DID. The voice terminals are all IP and work perfectly over our data network without QoS (surprised me).

Things I still want to try:

PC integration (softphone)
IP trunking with branch office.

What systems are you running and what stories (horror or otherwise) do you have to tell?
