asterisk users - Aug 2012 - can we install 10 PCI card on asterisk

Hi All,

i would like to know if anyone has done or having idea regarding PRI
terminations in asterisk.

i have a requirement where i need to support 80 PRI in one machine i have
found a machine which have 10 PCI slots available

now i am thinking of arranging 8port sangoma card in this pci slots so i
can arrenge 10 card in that.

is it possible to run system like that ? is it good idea , can asterisk
handle 2400 calls if machine size and RAM is good.

let me know ideas and suggestions.

thanks
Dhaval

Not a good idea :)

Asterisk at max we have seen supported 16 PRIs on single machine.

Last I checked, the highest channel number DAHDI supported was 1023, 
limiting you to some 34 E1 PRIs.

We've faced stability issues with more than 500 simultaneous calls on a 
single high-powered server, with no transcoding.  However, that's 
probably more a limitation of our own architecture and application than 
a hard Asterisk limit.

That sounds like having too many eggs in one basket to me.  If you have 
a problem with that single machine, you're going to disrupt 2400 calls 
when you do. A more distributed approach with multiple machines running 
Asterisk and multiple standalone PRI gateways will be much more fault 
tolerant if designed correctly.

I don't think Asterisk can handle that many DAHDI channels and I have 
never heard of an Asterisk box with more that 16 PRI's.

Taking a step back, do you really want to put all your eggs in one 
basket? what if the box fails? That's 2400 channels going down and 
unavailable until you fix it. That will cost a log of money and get you 
angry clients. It makes more sense to spread the lot across different 
servers. Besides that, is your telco willing to provide you with 80x PRI 
or will they insist on aggregating it to several E3 links or something 
higher (STM-1)?

If you really insist on going down this route have a look at FreeSWITCH 
or look at something like Cisco, Alcatel, Telco Systems etc.

Your best bet is a carrier class device from someone like Adtran and convert the
PRIs to SIP before passing the calls to Asterisk.

Hey All,

Thanks for everyone input on this, this was just mine thoughts to put 80
PRI line in that.but after reading inputs from everyone i think there are
some options to achieve it.

it means i need to put a gateway which convert my SIP calls to PRI line and
another options is to put
multiple asterisk boxes and each box have maximum 16 pri lines . now which
is best choice to work on further. also i need to consider hardware sizing
too as if gateway is expensive i would go with pri cards.
also if i choose gateway then  also i need to put multiple asterisk boxes.

let me know your thoughts.

thanks
Dhaval
