Mitel 3300 MX3 - E2tSP IP network dropped packets

[braindead2]

Does anyone know why we constantly get these maintenance logs for dropped packets, there is no IP phones on the system except the switchboard and just the SIP for outgoing calls. The customer is complaining of calls breaking up on both incoming and outgoing, but the incoming are via the ISDN..

Any Help appreciated

What is at IP 88.215.63.170? Either that device, or the path between that device and the RTC of the controller is the culprit.

 

[braindead2]

Gamma SIP server, but this is the 2nd controller and I have also swapped out the cisco router and still get the packet drops. The business DSL has also been tested by BT and its ok.

 

[kwbMitel]

That level of packet loss would definitely be noticeable to the user.

I suspect that your firewall is causing the issue. You need to open up the ports as per the engineering guidelines.



**********************************************
What's most important is that you realise ... There is no spoon.

 

[braindead2]

There is no firewall, there is only a cisco 877 router connected to a adsl. The cisco router just permits everything from the gamma server IP address regardless of port numbers..

The cisco route has also been changed out…

 

[merlin215]

Could be too much traffic and the device is dropping the packets due to congestion

I would bet ( not enough info to go on ) that it may be a server issue due to the server not being able to keep up with the voice and data traffic

maybe priority issues on voice traffic ??? Or the server not set up correctly ???

Dropped packets can be a few things most commonly unable to process and dropped , a local switch not configured for priority and a lot of traffic , late delivery , a bad Nic on the server , not set up correctly on the server , etc .


Tels are on your network and the ISDN provides the voice outbound lines as You say , are digital . Something on the network ( IP address above ) is causing your issue and I would bet the server or something on your network cannot handle the traffic !

Regardless , a Network trace would show you exactly where the bottleneck or cause is ...

 

[braindead2]

But there isn’t a network, there is a 3300 connected via one of the LAN ports to the cisco 877 which in turn is connected to the internet via the ADSL port.. The public IP Address is a Gammas SIP Server and I can probably assure that it’s not Gamma server that has the problem as they have hundreds of customers that connect to that server over the internet…
The ASDL has been tested by BT a few times and there is a good 10meg connection from it, so its not that either..

 

[wireman50]

What speed is theaDSL and what kind of results do you get from the various tests on

http://www.speedtest.net;

espeically the ping test for latency?

 

[Lundah]

What else is running over that ADSL circuit, and what's the utilization look like at the time periods where the logs are reporting packet loss? Does the voice traffic get priority?

 

[Billz66]

You say regarding the ADSL

"there is a good 10meg connection from it"

Adsl is by design asyncronous so whats the UP speed ?

dont assume that just because you are getting 10M down that your upspeed is at a sufficient level

If I never did anything I'd never done before , I'd never do anything.....

 

[merlin215]

Hey
What was the resolution ?
Did you find anything ?

Thx

[braindead2]

Getting BT to check the DSL again as its the only thing that hasnt been changed.
