Replacing old phone system
-
In addition to Elastix, Shoretel is another system that is pretty good.
I am unsure what the implementation costs are with it, but I found it to be an easy system to learn and administer. -
Do you have specific must-haves in terms of PBX functionality that you would like to share? That would help determine whether something like Elastix / FreePBX / some other Asterisk system would work for you.
-
@dashrender That is certainly doable. I'm just thinking for failover, etc. We have people who have phones that can't go down. Ever. Others have a one-hour tolerance, two, four, etc. Higher need for little to no downtime will increase cost and complexity to varying degrees. $150/phone seems to be a bit high but it depends on what they're selling. Digium did NOT invent Elastix. It's an open-source product. How did management react to hearing a number like 25K?
-
I will also say that they make TVAs for the digital phones that you could use to connect them to a back-end Asterisk system without having to replace the phones or cabling right at first. Then you could replace as needed as you go.

@NetworkNerd What is the difference between a digital phone and a VoIP phone?
-
@ajstringham
Digital phones do not have an ip address on the network and are going to require rj11 cables to them wherever they are located. It's an additional cabling need that is introduced that is not as nice as having everything ride your existing network cabling. They often have fewer features as well. For example, we used to have Avaya 5410 phones with our IP Offcie 406. The phones were easy to use and setup with the IP Office, but if we needed to put a new user somewhere that had no cabling for phones to it (though it likely had network cabling already), we'd have to pay for it. It's not as easy as throwing a switch in like with ethernet. -
@NetworkNerd Agreed. Ok, so they still work on RJ-11s and not RJ-45s. Got it. I wasn't sure. Thanks for the explanation. So the NEC phone systems you see in retail, etc. Those are digital?

@ajstringham
I would say you cannot assume it as a general rule, but is possible: http://advancedtel.com/products/nec-ipdigital-phone-systems. Older NEC systems may be digital. We have one at a location for which I manage the phones and PBX...soon to be replaced with Elastix.And it could be digital phones connected to a back end VOIP system like the one you see here. The phone system itself can be VOIP / digital / analog. The phones themselves could fall into one of those categories as well when we speak in general.
-
We are using ACD to move calls around to different hunt groups as the ACD dictates. Beyond that, we have Voicemail, about 30 DIDs and a 2 operator console. The operators have a software console that show them all of the phones in the system (these two buildings) and their status. They can also use the console to send calls to those users, change the users status, etc.
We don't have a specific conference ability beyond putting one call on hold and then calling another person on a different line (though a call in type conference bridge might be nice). The ability to give console access to more people would be nice as well (inter-tel wants something like $2500-$5k for each desk).

They said, why are you even talking to me since we have a $6K solution from the current vendor? and no problems that we are trying to overcome.

I can't tell you because they don't know. If I ask them they will of course say - we can't afford any downtime, but we know that's simply not true. It would be better to present options like
To be reasonably sure we suffer only 5 mins of downtime will cost $20k
To be reasonably sure we suffer only 1 hour of downtime will cost $12k
To be reasonably sure we suffer only 4 hour of downtime will cost $6k
etcThen they can decide what level of risk they want.
As I said, they've already decided from a critical situation (think the surgical center) that they can use personal cell phones in case of an emergency. When it comes to patient's ability to call us, or us call them in non emergent situations, personally I think we could afford 4 hours without to much image damage. All calls could be routed to the answering service within 10 mins of the outage starting so the calls would not be simply ringing with no answer. -
@Dashrender Let me ask you this:
Assuming you got all new phones, how many would you need?
Basic phone (make/take calls, transfer, hold, conference in):
Conference room phone:
Secretary phones:
Anything else:
TOTAL =What is your internal infrastructure like? Things like a hot/cold model could work if you don't need 99.9999% uptime with a VM locally and a failover in the colo or even a second local instance. Or an on-premise and cloud failover solution works too. Either way.
-
Let me say first that our current phone system has not backup DR solution - other than call the vendor. If the Inter-Tel 5000 dies, I grab my cell phone and call the vendor. They grab a 5000 off the shelve - a hopefully current version of our call processing and drive to my site and install the new unit. This costs us nothing until we use this option.
-
@ajstringham Let me get back to you with the count.
-
@dashrender I'm thinking for a VoIP system if you are replacing the backbone of th esystem, replace the phones. No point preserving ancient technology. Like trying to preserve XP. Waste of time and money. Just getting ideas.
-
@ajstringham The presented solution is as follows:
Replace the Digital switch with an Inter-Tel 5000 (VOIP) switch.
Connect a VOIP to digital gateway appliance that all of the current digital phones will plug into and work as normal.
Done.We had a meeting with the vendor yesterday and the suggested that as digital phones die, we replace them with VOIP phones. I had to remind management that that would mean they would possibly need new wiring, and even if no new wiring, they would new POE/power injectors/power bricks for each VOIP phone put in. Frankly I was surprised I was told that was doable.
-
@Dashrender Do you not have the drops necessary for another cable? As far as PoE, why? I'm assuming you're using desktops at most workstations. Just passthrough the phone to the computer so you have one line back to the switch/patch panel and you don't need extra drops. Replacing the system and not the phones would be a foolish move IMO.
-
@ajstringham
This building was cabled long before I came along. Each station only has one ethernet drop. Plus about 1/3 of the drops are in places without a computer, so there is no pre existing cable to use.
What do you mean why PoE? Because I hate using power bricks, and am not fond of the idea of using power injectors (though I can't tell you why - it's just a personal thing, I suppose I could get over it).Let's assume that building has 65 phones and you said that $150 was a bit high so will lowball it at $100 each - that's still $6500 in phones before I look at adding cabling and PoE switches.
But... now in writing that previous sentence... if I replaced all the phones, they can all connect to my current Inter-Tel 5000 so I could dump that expense and be over only the cost of cabling and the PoE switches. ... wait that thought won't work because phones for my current phone system cost $250+ ea ($125 for the phone and $125 for their IP license). So that ups my price on phones alone to $16,250.
-
@dashrender I don't think you understand. If you have a computer at a location, it has a line. Plug that line into the VoIP phone. The phone as a port that goes from the phone to the computer. One "backbone" line you could say for two devices. No need for PoE or injectors because phones are powered via AC plugs. As far as licensing, yea, spend the money on new phones. Elastix has no licensing limitations or extensions cap, etc. What's the issue here? All you need is the extra 3 ft Cat 5e/6 cables.
-
@ajstringham I do understand that I only need one ethernet port at each desk to run both a phone and the computer (I'm doing that now in the second building that has VOIP phones already.
I want PoE because I don't want to use "phones are powered via AC plugs" as you put it - I said power bricks in my previous posts. More plugs under the desk just invite more problems (and add to the cost because most phones don't come with them) Since I have to have the cost anyway power brick or PoE switch, I'll take the switch if available.
Most phones come with a Cat5e cable so I wouldn't need anything there.
I did understand that Elastix does not have a licensing cost, it's just the phone cost itself.
Earlier when I mentioned that Asterisk was made by Digium ( I didn't say Elastix was made by Digium - should have said Mark Spencer of Digium) is that wrong? And a search I just did showed that Elastix is based on Asterisk and several other projects.
Let's pause on this conversation until I get a full phone count.
