Can I utilize my current pbx phone system hardware I have at my current location, while implementing additional voip hardware for a new location I am building?

Hello Jonathan,

Yes you can implement a new VoIP based PBX or VoIP IP Phones on the new location an let it interconnect to the old PBX.

The trick is to have a VoIP gateway or IP PBX (with ISDN / T1 cards) connected to your OLD PBX at the 'old' location and then let the VoIP PBX / VoIP phones on your new location talk to that VoIP gateway / IP PBX on the old location.

Because there is an interconnect between the IP PBX / VOIP gateway and the old PBX, you can let the calls flow between them.

Means that the new IP phones on the new location can call the other internat 'old' PBX extensions and vice versa.

Another cool thing is that your OLD PBX and the connected old phones can even call through the connected VoIP gateway / IP PBX and then call outbound to normal telephones. Through XeloQ for instance ;-)

Your old and new phones van then save UP TO 90% on International calls.

Even you can order telephone-numbers form us that can end up on your old or new exchange. This means that suddenly you can get foreign telephone-numbers ending up on your old (and new) PBX / extensions.....

You can start this by getting an Asterisk IP PBX (even running on an old PC) or get a VoIP gateway with (limited) PBX functionalities (like a Vegastram or Innovaphone).

More information: just mail me !

And take a look at our website of course: http://www.xeloq.com

Yes you can. If I understand you correctly, you want to keep your existing PBX at one location, build a VoIP system at another new location, and unify these two systems. You can set up SIP trunking to your current location, providing your traditional equipment with an IP network and enhance your phone system's features. You can then set up a VoIP phone system at your new location and link the two locations over that IP network. If you have any questions or want to learn more, shoot me an email. jriordan@stage2networks.com

You can indeed acheive what you are looking to do. Drop me an email so we can discuss what the complete objective is in greater detail.

ZThis all depends on the brand and level of the current system. We have experience in doing this for real estate customers. The question is how many features do you wish to share globaly, and how much redundancy do you wish to have?

Hi Jonathon,

So far everyone is right to a degree - but I agree with Bob Brock - the complete answer to your question does depend heavily upon what you currently have in place and what features and functionality you need within the Network you create. Almost any of the major players - Avaya, Mitel, Cisco, etc., (even Nortel) can play nice together with some sort of Gateway / T1 / SIP scenerio. The big difference in your decision will be with the provider you choose to assist you.

Let me know if you have any questions - I have about 25 years of experience with voice and data communications.

Hi Jonathon

I agree with several of the others, it does depend upon your currrent equipment, what you choose to implement the new VoIP network, and what features / functionalities that you require. In todays economy it is very wise to use existing infrastructure where possible; thus, lowering TCO.
I have successfully integrated Cisco/Nortel/Avaya and others within the same network (TDM / IP / SIP) and leveraged the existing infrasturture where possible. But as Dorothy Jones has stated there are other factors that are based on the provider you choose. There is also a number of other things which should be considered; including dialing plans, E911, and other applications that will be part of the business requirements that will drive the technical decision.

If you have any further questions or need any further assistance please contact me at (936) 465-9806. Have 25+ years in telecommunciations and IT with certifications in Nortel, Avaya, Siemens, and Cisco.

All good comments to arrive at the answer - Yes its possible. The devil is in the details, as they say, and one of the items that may be encountered (and which I haven't seen mentioned yet) is the issue of Voice Mail. If the current PBX has VM, and the new location/system is expected to integrate with the existing VM system (i.e. forwarding of voice messages, voice messages broadcasting to multiple VM boxes, etc.), then this often presents more of a challenge than the voice. Its relatively straightforward to implement an internal (3 or 4 digit) dialing plan, but to have that same functionality translate to the Voice Mail platform, is a bit more challenging. Obviously, more information is needed regarding the curent system, and whether the new system is to also have its own VM or try to utilize the existing one. Just don't overlook the other applications (like Voice Mail) when thinking about integrating a PBX with a VoIP system....

Jonathon,

Based on your original input, I'll guess that the main site PBX is not a hybrid PBX/IP switch.

1. If you want the benefits of SIP trunking for the main site, there are add-on units (usually 4, 8 or 24 channels) that can provide the existing site the benefit of SIP trunks.
2. There are very small VoIP units available. There are VoIP units that can start small and expand as you require additional support, up to and including remote site support against the day you want to replace the existing PBX and capture the main site on the VoIP system. The expandable units cost more up front, but you won't have to throw equipment away as you would if you exceed the capabilities of a very small unit, and you will have saved money down the line when those expansions occur. You might build a year or two into your calculations with your management team. An idea of where they hope to go will tell you what direction (very small versus expandable) you probably need to take.
3. At least some of those systems can add very intelligent outboard functions, such as call center applications and UC server support with expansion capabilities.
4. If you have a very good telecom group and a very good IT group where competent people in both groups can work together to bring about a good result including QoS (quality of service), sufficient bandwidth for both voice (always realtime) and data, and the infrastructure to support those needs, that is best. The cross development of the people in those groups as they support your company's development will bode well in the future.
5. If you lack those skills on either side, purchase them. Get the best company you can find because something done well up front will save you time, money, lots of anguish, and possible loss of business later.
6. As noted before, sometimes spending a bit more money up front will solve a problem later on, as with unexpected growth or incorporating the main site into a VoIP multi-site system, with internal personnel development, or hiring/renting the best to get the best result for your company and your customers. The old adage says time is money.
7. The use of automatic network dialing (by any other name) should cause the main site PBX to be able to add digits to an extension number which terminates at the remote (VoIP) site. This should also be available on the VoIP switch, bringing about the same result. We do not care if John or Mary is at Site A or B, we want the system to take our three or four digit extension and deliver it to the right phone (or the voicemail behind that extension).
8. Last item. If you have contacts or peers with some experience in what you hope to do, including vendors (good service, quick response on issues,?) and products (more than six months in place so they will have a real feel for them), chat them up and benefit from their experiences. I believe you'll find a lot of the smaller vendors have very good service reputations, and a standard of excellence will serve you and your company well.
