[asterisk-users] Quality problems with ISDN PRI

[Carles Pina i Estany]

Hello,

We have an Asterisk server with a TE410P Quad-Span togglable E1/T1/J1
card, 3 SPANs configured and OK and one SPAN unconfigured.

In our tests it works fine, but when it has a big laod of calls (say,
from 40 to 60) we have quality problems: some calls has the sound
cut-off (during the call, voice was not stable)

The IRQ card is alone, CPU load was not high, network was fine for sure.
This server is receiving the calls from SIP channels and routing to the
primaries. It's a HP server, multicore, multiCPU.

I'm wondering if someone has had these kind of problems (quality
problems, sound cut off) with 40 and 60 calls but not with 2 or 3, using
Digium cards.

Bit later I will call to Digium but I thought that here there is lot of
people with lot of experience with these cards.

Thank you,
