Vicibox server performance with SIP

[dimorry]

Hi Fellows,

I have a 100% dial out operation, using manual dial (for now) running on a dell poweredge Dual 3.0 GHZ processor, 4 GB RAM and 10k SCSI hd.
I have a dedicated 2mb link and when i get over 8-10 simultaneous calls the agents start complainig about breakage and low volume calls. I'm not using any kind of compression.
I tested bypassing the vicidial server, connecting directly to my SIP provider(passing through my nat) and started to get perfect call quality. I also checked my nat networkcard at that time and it didn't even passed 1.3 mb of data being transfered which pretty much made me discard carrier and sip provider problems.
I have on this same box a digium board connected to a E1 and when I dial through the E1 i can have over 20 simultaneous calls without a problem.
I only make calls through E1 when I'm not making calls through SIP. I guess that with the digium board installed, i could discard timing issues also.


Is there a particular config for using with sip i'm missing here?

Thanks in advance,

Mauricio

loadavg on the server when this happens?

I don't know a lot about linux, the information i posted is a print of the top command. Does this give you what you need?
Is there anything else I can post?
Thanks again.

To ensure that you're using the Sangoma as timing source type this in your asterisk CLI:

Code: Select all

dahdi show status

or, if you have Zaptel:

Code: Select all

zap show status

I really have the same problem as yours, so I can tell all the tests that I've made

[dimorry]

I have a digium board installed.
here is the print from zap show status
Description Alarms IRQ bpviol CRC4
T2XXP (PCI) Card 0 Span 1 OK 0 0 0
T2XXP (PCI) Card 0 Span 2 UNCONFIGUR 0 0 0

It seems OK, take a look at "my" thread, I think we have the same problem...

Thanks for the help. I've found a problem when i ran the mtr command.
Apparently i'm loosing up to 7% of the packets in my NAT, and over 10% with my provider on the other edge.
