[asterisk-users] Maximum number of PRI calls on 1 asterisk box (no HW echo)

[Zeeshan Zakaria]

A good idea is to call sangoma tech support or email them with your config
but as per my knowledge and experience and as per Rhino's tech support and
Digium techsupport suggestions which I got when dealing with a lot of spans,
you can't have 10 PRIs running under one asterisk. You'll need to physically
remove one 4xPRI card, and set it up on a separate server, and configure
your dialplan accordingly.

I'm running 2 Sangoma A104D cards and a Sangoma A102D card for a total
of 10 PRIs. Right now I have 9 PRIs configured as 3 DAHDI groups. 3
PRIs are in a group for local calls, 2 are grouped for long distance,
and the last 4 connect to our Toshiba PBX for users still on digital
phones.

These cards are in a Dell R710 with two quad core CPU's. System load
hovers just below 1 with 30-40 concurrent calls. Half the calls are to
SIP phones connected over OpenVPN running on the server. The other
half are DAHDI to DAHDI bridged to the PBX.

Software wise I am running CentOS 5.4 x86_64, Asterisk 1.6.1.18, DAHDI
2.2.1, libPRI 1.4.10.2, and Sangoma wanpipe driver 3.5.6. I had some
issues with newer wanpipe drivers and kernel soft locks. I also had a
PCI dma timeout issue which required a Sangoma firmware update. Since
then it has been rock solid since with 22 days of uptime.
