hi

I am setting up a test lab using BRI to connect two pbxs together.
I am new to BRI / ISDN. For now I am just need some advice
on what hardware which supports NT mode to use.
I am also looking for info on setting up the BRI card in asterisks,
setting the channels, mode type etc.  Once I got a good grip
on ISDN BRI basic rate, my  goal is to have 2 BRI ports which will be connected
to Telco

and 2 Ports for Inter PBX.

The hardware should be able to support NT/TE modes configuration
for each port.

thanks in advance

Hi,

We have a user who is putting large call volumes through Asterisk, and
wants to BLF monitor up to 90 extensions. We are struggling to find a
handset that can keep up with Asterisk

1) Is there a handset that will do this?
2) Is there a different (standard) way to send BLF and allow directed pickups?
2a) Or even a handset specific way?

Asterisk handles the BLF volume fine, even on quite low-end hardware,
but we cannot find any handsets that can cope with it longer term.

Our test involves about 10 BLF-NOTIFY messages per second to each
handset with a 5-second pause every 5 seconds. This will either crash
or render unusable all of the following combinations:

snom360 + 1 x sidecar
Yealink T28 + 1 x sidecar
Yealink T28 + 2 x sidecar
Cisco SPA504g + 1 x sidecar
Cisco SPA504g + 2 x sidecar
Cisco SPA525g + 1 x sidecar (reboots often)
Cisco SPA525g + 2 x sidecar (reboots quickly)
Aastra 55i + non-LCD sidecar

Did not try Polycom as they do not do directed pickup and only small sidecars.
Linksys SPA962 with one sidecar is “OK” but is discontinued hardware.

Help?

Thanks,
Steve

I’ve had good experiences with an OpenVox A400P, once you’ve done the “Dahdi
dance”, it settles down to be very reliable. Reasonable price, too. I bought
mine from Voipon, although I’m sure a bit of shopping around will find other
vendors.

I have a pair of Asterisk servers which are happily routeing VoIP calls.
I want to hook one of them to the PSTN. Given that I am in the UK, what
is a reasonably easily-available device to provide an FXO interface from
a Linux box, with a minimum of faffing around with drivers? Just one
line is needed, though in theory two might eventually be useful. My
usual white-box hardware suppliers don’t seem to play in this field.

Also: I’ve heard good things about the PAP2T for getting analogue
handsets to talk to a VoIP server. But all the ones I can see on eBay
are PAP2T-NA models. Will these work with British handsets? (Obviously
with a plug adaptor to put the BT jack into an RJ11 socket, but that’s
relatively easy to arrange.)
