Voip line, PBX, Mess!!!

HighlyCooL

Hi,
first of i hope this is in the right section.

In the middle of planning some my phone system out and i found out about pbx's.

i dont know how this will work but any feed back would be great.
Well heres the new plan:

Broadband> Router> Ata> 2x8PABX> 8 phone lines in the house.

ok i have the house wired with cat5e and was planing on puting in sip fones in each room. but i found out about pbx's. the real question is that if i do what im saying above will it alow me to have an 353 1 fone number in the house that will ring selected fones and also alow me to ring the kitchen from the atic say.

i hope this makes some sence to some one.

thanks in advance

Hi,

Yes a PBX will allow you to control how 353 1 numbers are routed to the phones, when you say 8 phone lines do you mean you have 8 points in the house i.e. 8 SIP handsets?

A Linksys SPA 9000 + SPA400 Analogue Adaptor + 8x SPA 921 SIP phones would be perfect for this.

So you would have

PSTN phone Line (353 1) --> SPA400 --> SPA9000 --> 8 port POE switch --> IP Phones

The SPA9000 supports up to 16 handsets so there's loads of room for expansion. It would also allow you to use VOIP for outgoing calls e.g. Blueface.ie.

Let me know if you need any more info.

Cheers, Joe

im sorry but now im really really lost, i thought if i use a PABX that i could use a normal POT telephone. and since an ata converts a digital signal to an analoge signal it should work then alowing me to have all the fones linked. thus saving the expence of buying sip fones!

joePC

Yes you can do that aswell,

so its,

PSTN line (353 1) --> PBX with 8x FXS ports --> 8x POTS Phones

So you need a PBX with 8x FXS ports, there are a couple that come to mind, The Xorcom XR1000 Astribank Server or the Pika WARP Asterisk Appliance - again both can be setup with SIP trunks for VOIP.

Depending on budget you might find a cheap siemens or panasonic system on ebay that would do the job.

HighlyCooL

yeah i was looking at a cheap pabx on ebay. i just want a decent ata no. hoping the have blue face in by christmas and that why im looking for clarity.

so joepc your saying my theory will work on paper?

can i direct both 076 and 3531 number through one ata and have them ring different extentions, or do i need 2 atas. and joepc since i take it your in the business, can you recoment one.

thanks im starting to get a system in my head that will work

joePC

I think there is a little confusion here,

On one hand you want a PBX that will allow you to run all 8 POT phones, extension to extension dialling etc...

On the other hand you want an ATA to connect your POT phones so they can send and receive calls over VOIP / Blueface.

Just to clarify,

An ATA will allow you to convert your POTS phones to SIP/VOIP - So you setup your Blueface account on the ATA and connect a POT phone.

You can only run 1/2 phones from an ATA e.g. The Linksys PAP2T or SPA2102

This won’t allow you to do extension to extension calling etc...

---

If you want to run all phones from a PBX and integrate VOIP so you have extension to extension dialling and full control over what numbers ring what phones etc... Then you will need a PBX that’s VOIP compatible like the ones I mentioned earlier.

HighlyCooL

ahhh i see. i know it couldnt be that easy. haha

but would connecting a pbx to an ata no be like connecting 1 fone to a ata

joePC

:-) It is possible to run certain types of PSTN gateways including Asterisk+TDM cards off legacy PBX's but it only really works if you have full configuration control at both ends.

A basic ATA link the Linksys and a OEM PBX - I’m not saying it's impossible, just very unlikely to work and given the amount of troubleshooting involved it might end up a waste of time.

HighlyCooL

yeah i guess your right. no point in wasting time and money on a system that half works! so in your view what should i get to give me at least 6 extentions that alow internal calling, 2 numbers from blue face (1x 353 1 and 1x 076) alowing me to to use POTS telephones and sip fone.

joePC

I would recommend using a Xorcom Astribank Server XR1000 + 8 FXS

This is an Asterisk appliance that will allow you to have 8x POT phones connected as Extensions, will support upto 30+ SIP/VOIP Extensions / phones, has all the features of Asterisk and is easy to configure.

Cat5

What you want to do is certainly possible using a the cheap and cheerful analogue panasonic phone system (tea-308) ..you simply use the lines from your ata as the main co feed in to the system..(2 lines from a pap2).
Result 8 individual extensions that can all ring each other or ring externally.. Incoming calls are programmed to ring whtever extensions you require or all..Cheap and simple.;)

HighlyCooL

thats what i thought, if an ata will only supply one fone, would a pbx not be like one fone?

Cat5

yes... essentially....if you programme the ata with two lines you can make two external calls at the same time..or make one receive another etc etc..

HighlyCooL

yeah was hoping that because i can do that for about 130 euro max. and if it goes wrong its not that much money down the drain haha

Cat5

Dont worry.No money wasted...It'll work.. Good luck with it..;)

HighlyCooL

sure ether way its worth a shot, i have a bid some hard ware that joePC said, but if i dont win it all just go with my first plan. thanks for your help guys

I have installed the SPA9000 and 8 x SPA962 extensions. Got a Smart Telecom connection 4mb/1mb ADSL2+ uncontended service. Ported my phone number to Blueface and now can have 5 concurrent calls with excellent sound quality, and 1 line rental. The PBX and Shared Line Appearance functions make this an excellent system and I'ld highly recommend it.

HighlyCooL

i see,will that unit alow POT tellephone's?

LeViat

No. Not directly, but I do have 2 x PAP2T analogue/VOIP converters which I use to convert fax machines to VOIP enabled devices. If I get a chance I will see if I can get them to register as extensions on the SPA9000. It's not a configuration I'ld try since these cost about EUR50 each (plus a phone [or two] to attach to it) and you can get SPA942 phones (note not 962s) for about EUR100 and gain A LOT more functionality with these.

IF you go down the phones route you should also budget for a PoE switch so you don't need to purchase power supplies for the phones - which just make everything look untidy.

HighlyCooL

i kinda have to use pots as the ol pair arent great with "these new gismos" im getting a PoE switch for other this, so im not restricted. no to worry tho it will be after christmas before i do any thing any way

LeViat

Just bear in mind when you set up a POTS phone and an ATA theat you have a bundle of stuff at each extension. CAT5 to ATA, Power to ATA, RJ11 from ATA to phone and possible power to phone.

Regarding the "oldies" an IP phone is still a phone where you lift a receiver and press a few buttons with numbers on them!

HighlyCooL

the house is wired in cat5 all i have to do is put the ata in the cabinet and make a patch cable thats got an rj11 on one end and a rj45 on the other which i can do. im going to try do it with an ata and a small PABX but it will be late jan early feb when i get around to it
