IPO fail at around 80 SIP sessions

[sagbab]

IP500v1 8.0(53)

The IPO is supposed to support 120 SIP sessions, but it doesn´t seem to be the case. A bunch of wierd stuff starts to happen around 80, sound issues, calls disconnecting, delays when trying to call out and so on. I just wonder if anyone know has encountered this problem before and has been able to solve it?

How many VCM channels do you have on which type of VCM cards?

BAZINGA!

I'm not insane, my mother had me tested!

 

[sagbab]

2x VCM 64, 128 channels.

I should look in the network and not in the IPO.

Hi Bas!

Good to hear from you, was at the same IPOCC "BootCamp" as you in May (one of the swedes in the back).

Well, I too was sure it was the network when starting to look at this, I mean it always is. But looking into it I slowly had to give in to the option that it might actually be the IPO. Today I started listening with other techs around here and one had encountered this problem before and set up a test environment at his office to test it, and with a dialer found out that things was starting to break down at, in his case, around 90 calls.

At this specific customer they are also having a different PBX remote, with IP phones at the same location as the IPO is placed. They are not experencing any sound issues even though it uses the same network. The problems are also not constant, but only when it nears 80 (82 licensed channels).

I can add that they are using analog phones, phonemanager and CCR that might add to the information needed to be processed by the IPO, and also VM pro with queue position that keeps hitting the ceiling of 10 VM channels.

Hi sagbab, i was there as i was sitting next to Bas1234
What you could do is open monitor and status and select performance data and see what happens.

[sagbab]

Aha! there you go well, the one who did the test was the swede sitting right next to you both, one of the ones who drove the wrong way ending up being half a day late for the thing

I've never actually used that before, which is a shame really. Any sugestions on what to look for that can give me a hint on what might be the cause?

 

[tlpeter]

You can see lan 1 and lan 2 statistics.
I do not know what it all does either but you should be able to see a difference when the problem occurs.
There is also an option with memory data.

I wouldn'd be surprised if Avaya advise to upgrade to a server edition.....

 

[daken]

What codec are you using for the sip trunks?

 

[sagbab]

Ok, thanks tlpeter!

Intigrant, I would expect nothing else

Hi sagbab,

I'm good nice to hear from you.

The slots are numbered 1 to 4 from left to right. They can be used in any order. However if the capacity for a particular
type of card is exceeded, the card in the rightmost slot will be disabled so try not to use the right most slot for a VCM64
Also make sure the network port is set to AUTO/AUTO because by default the IPO cannot be changed the port settings to Fixed Speeds or duplex settigns.
