Hello all,

Can someone recommend what hardware to use for a 1000 analogue line capacity asterisk PABX?

Thanks Mitul,

The server spec is okay but I need information on the fxs hardware to use.

Regards

Hi,

For analog, I really like telco grade channel banks.

I would recommend the adit 600, there is a good market on Ebay, and you can do 48 channels per adit 600, with 2 T1 interfaces.  Having onsite spares would not be an issue (cost is low).  You can put two next to each other in a rack, taking up about 2U of space per 2 channel banks.

You could service this with six eight port T1 cards, or with eleven/twelve quad T1 cards.  I would distribute across two, three, or even four servers for redundancy/resiliency and load balancing.

Thanks Harry.

I will check and revert. I hope it work perfectly with asterisk.

There is definitely no way you should put 1000 lines on a single box. To be honest I do wonder what you want to do with 1000 lines as your description probably changes the recommendations.

Kind regards,

Matt

Thanks
When I designed the server, I catered for only IP phones but customer want to discard the existing analogue pbx while they want to reuse their cables and analogue phones.

+1
spending money to get that many fxs ports is going to negate any savings of reusing analog phones instead of buying ip phones
1000 analog ports sounds like hell and if it was me I  would be embarrassed to have a setup like that tied to my name if I was a consultant etc. Someone will come in after you and ask who set it up and the customer will say you On Feb 17, 2016 4:23 AM, "A J Stiles" <asterisk_list@earthshod.co.uk (asterisk_list@earthshod.co.uk)> wrote:

That would be the expensive route.  The inexpensive route would be to buy FXS ethernet gateways, like this: http://www.voipsupply.com/grandstream-gxw4248.  You could then get by with a single reasonably sized asterisk box (probably two setup as HA) and no need for expensive cards or complex channel bank setup.  We have done many hotels this way with great results.

Hi,

All of the back and forth of Analog vs VoIP handsets tend to ignore some of the basic issues.

What type of cabling is in place, does it need to be upgraded to do Ethernet, etc.

The "gateways" can be handy if there are many closets where the wiring terminates AND you have Ethernet to these locations.  That being said you probably should have some amount of backup battery power any location you put a gateway.  You can also do this running your own T1 lines to the closet and channel banks in the closet.

If all of the lines come back to the same place, you only have to have backup battery in a single location.

I have seen enough hackish VoIP deployments, that I can see many cases that Analog is cleaner.  For example, IBM Type1 cabling, can't run PoE, so they installed wall warts with each phone...

You also have to look at the use case.  Doing an "office" with Analog is very different then doing a phone in each classroom at a school, or even hotel phones.

The channel banks, even if you have to buy multiple to get the right cards, should average under $200 each, 8 port T1 cards are about $2K each, total cost to service 22x$200 + 6x$1000 = $10,400, or about $10 per port, and you should be able to do it cheaper then this.  This is of course using Ebay pricing, new would be much higher.

The gateways run about $25-30 per port, even for the lower end (like the Grandstream below).

Cabling costs depend greatly on location, around here it averages $100/drop in office environments, if your only doing one run to each room, it gets even higher, this is where the real cost of using VoIP handsets comes into play.

What about leaving the old PBX in place and trunking it via ISDN to the asterisk server. 

We use rhino 24 channel bank but are 2U for rhino + 1U for patch panel. (RJ21 cable so might be able to use existing ones if they are RJ21)


Used USB xorcoms a while back, things may of changed but if one is down and reboot server then asterisk doesn't come up.
