XNET networking -voice quality

[luxmitel]

Hi,

I have install a customer with 2 controllers in two diferents country's connect by XNET with a VPN MPLS with 2Mb of bandwidth.

the problem is that I have the ring tone on the phones but i have many many cuts during the conversation.
I can see on the voice quality form that the call have loss packets.

Do you know a form to test if the problems comes from the Configuration controllers or if comes from the circuit.

I have the xnet trunk establish and it's a new installation and a new circuit.

Thanks

thanks

Will the IP phone analyser work across the xnet?

You can view jitter, packet loss, and latency (delay) statistics for Mitel IP phones in the Voice
Quality Statistics form in the MCD System Administration Tool. The form also lists other useful
information such as the device type of the endpoint, the last CODEC used in the call, the IP
address of the subnet and the IP address of the endpoint.
The following forms in the MCD System Administration tool support voice quality statistics:
• Voice Quality Monitoring
• User Authorization Profiles
• Voice Quality Statistics.
To view the voice quality statistics for a call from an IP phone:
1. Log into the MCD System Administration Tool.
2. In the Voice Quality Monitoring form, ensure that Voice Quality Monitoring is set to True.
3. In the User Authorization Profiles form ensure that the User Profile associated with the
Enterprise Manager has "Application" enabled in the Access field. This allows access to
the MiXML management.
4. Place a call from the IP phone that is experiencing the voice quality issue. If the problem
is intermittent, ensure that you view the statistics while the problem is present on the call.
Because the data network is dynamic, you may not see evidence of a voice quality issue
if you check the statistics during favorable network conditions (for example, during a period
of low traffic).

I have already check with the Voice Quality Statistics form, it was there that i saw the loss packets, arround 66%.

Maybe with the IP phone analyser is more precise.

66% packet loss is silly high. Either the calculation is wrong, or there is something else missing from the scenario. Voice calls can take up to around 2% loss before it's noticeable. You're talking about over half of the conversation is missing.

Wireshark is the most precise you can get....see what it says.

Do you really mean XNET or is it IP Trunks?

Does the MPLS have a reservation of bandwidth for voice? How many IP trunks did you setup between the sites?

I would think that it is very likely the issue is network. What sofware load? The newer software has bandwidth management in it to restrict the number of IP calls based on bandwidth available.



I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

We have several IP paging units ON 3300 controller and wondered how can i stop the ringback <THROUGH SPEAKER> before paging announcement - pretty annoying.

we set the paging unit up with extension
user and device 5010 IP
Set a speed call 0993 with dial string *3721070

I tried the pause # and stil lsame issue.

Thanks.

The problems cames from the circuit MPLS. it was not very well configured.

thank people.
