[Asterisk-Users] MultiBRI in Australia - found one - maybe

[Craig Guy]

Being USB 1.1 is not a problem - there is more than enough bandwidth for a 
BRI in USB.  The handsets used in the BRI install are Snom 360's with 
firmware 5.3 and internal users have complained of slight echo, however I 
believe this is more to do with the Snoms than the Draytek adapters. For 
faxing use we have installed a Grandstream ATA 286.  I haven't had any 
feedback yet regarding problems or success with faxing for this customer.  I 
would have expected to hear of any problems faxing by now but I will try to 
follow it up, however as long as the latency is consistent (ie minimal 
jitter in the USB stack) it shouldn't cause any problems for fax.

At work in our own office we have two SNOM 360's and people with them also 
complain of slight echo. (We are using TE110p PRI for PSTN).  The rest of 
our office use a combination of Sipura 841, Cisco 7960 and Grandstream BT101 
and there are no echo complaints with any of these non Snom handsets, so at 
this point it doesn't appear that these BRI adapters have echo problems.

I have ordered one (for $71 from the supplier you mentioned, although I
have since found another supplier who appears to have them for $55!!!)
and will run whatever testing I can.

Someone from Cologne has commented that because it us a USB device,
there may be some latency issues (which will amplify any echo problems)
and I suspect that faxing may also suffer a bit. They are also only
USB1.1, but I'm not sure if that's a problem.

Have you tested faxing? Even if faxing doesn't work well enough to be
useful because of the delays, I think this is a very nice solution to my
problem (lack of BRI hardware in AU). Thanks again for bringing it to my
attention!!!
