[Asterisk-Users] PRI issues with TE410P

Hi Tan,
I have already turned off the HT from the BIOS (while it was enabled,
asterisk was not even stable with 2 pri's).
Further I am using the same kernel (2.4.25) with SMP enabled, that u
mentioned in your email.
Basically I think Scott is right in his emails, that libpri's and zaptel
driver for t4xxp are not really optimized and they really need tunings
in case when there is certain increase in number of calls .... Also I
cannot afford to get a system higher than the current specs.
Yesterday I had the same situation, I gave the IVR solution using te410p
to a company. They advertised on TeleVision and then we had a rush of
calls landing on the system (about 30 calls in 1-2 secs and 60 in 3-4
seconds time). What I have observed is:
1. Asterisk is stable upto 2 PRI's ... no call drops no errors.
2. As soon as I plug in the 3rd pri (3rd pri is confirmed stable), it
starts dropping the calls current landing as well as the previous stable
landed calls. All calls get dropped and PRIs' start syncing / unsyncing.
3. On the other hand I have also a dialogic server with 4 pri's in it,
and it was a rock solid ... going to full 120 calls ... btw: server is
just P3 700Mhz, and I have not noticed a single dropped call.
4. My configurations were checked by Mike (@ digium) ... and according
to him all things are fine, zaptel,zapata,extensions.conf ...
Thus when there is a smooth and gradual load of upto 3 pri's system will
remain stable, and when there is an instant call load it becomes shaky.
Also I will request those who have successfully done similar setup, to
post/advise their linux flavor (and updates), asterisk configurations,
kernel configuration, other system tweakings.
I want Mark from Digium to take special interest in solving and
recommendation on these issues, coz I have confirmed orders of 3 te410p
boards and one e100p (for which I mailed to Greg as well), but now I am
feeling reluctant to face the client.

Azher Amin

Before going to gentoo or another version of linux, try the following:
1) turn hyperthreading off in the BIOS. It's probably called something
like "virtual cpus".
2) Use a vanilla kernel from kernel.org e.g. 2.4.25.
We used to have times when the system would just hang. Using a
non-redhat kernel seems to have resolved that. We also use Gentoo, but I
warn you that it is not the easiest flavour to set up!
Hope that helps.

Dear,
Are you using Redhat9.0, coz I discussed about this yesterday with mike
in Digium, and he said that this is normal with Redhat (due to its SMP
handling problems), further he suggested to shift either to redhat 8 or
debian. You can try debian or gentoo.
I will try gentoo tomorrow and will see this behavior again.
Regards
Azher
