Insufficient Bandwidth Alarm
« on: September 20, 2021, 02:10:08 PM »
Within the last month or so we have been getting several "Insufficient Bandwidth' alarms.  We have the Mitel 5000 HX Controller & 5340e IP Phones.  We run MiVoice Office 250.  We have Dell Managed switches. When a person is on a call and the alarms prompts the person on the call will hear a couple beeps and the call will cutout or drop.  Anyone have any experience with this?

Sometimes these are frivolous errors... Insufficient Bandwidth alarms can be disabled in System Flags.

Every time the phone get a Insufficient Bandwidth error the call will cut out, so I don't think I should be ignoring the errors.  It's really frustrating and I am getting many complaints.  You would think Mitel has a solution or switch configuration to help with theses?

Are your IP phones sharing the same data port, the phone plugs into the data jack and a PC connects to the back of the phone? Also you should setup vLans for data and voice and tag the ports for voice with Qos.

Computers and phones share the network.  I have a VLAN for data and a VLAN2 setup for voice.  We don't plug computers into the phone LAN port.

PMCmikem,

What type of traffic shaping do you have for the Voice VLAN?

It should have priority over the Data VLAN as it is real-time communications.

Thanks,

TE

Data and Voice are separated through VLAN's.  Our voice VLAN has QoS setup and has priority.

Just wanted to add... another MiVo250 setup here and getting the same alarm and symptoms on end user side. Separate voice VLAN. I'll check traffic shaping.

Guys,

Have either of you had issues with audio when receiving the insufficient bandwidth alarm?

If the answer is no then what you can do, instead of turning it off, is to adjust the parameters it uses to determine insufficient bandwidth.

Go to System>IP-Related Information>Call Configurations and within each one you will want to change the following parameter:

Average In Time Frame Percentage Threshold: 45   

If you want to remove the alarm from ever being used by the system, not sure why you would though, you have to do two things.

Set the Average In Time Frame Percentage Threshold to 0

Go to System > Flags

Insufficient Bandwidth Alarm: No   Combine with Configuration settings to remove the alarm completely

Thanks,

TE

Thanks for the reply. The lady that reported the problem to me: "Calls are dropping, calls have static, phones reset randomly, there is insufficient bandwidth." So I definitely want to know the next time this happens.

I'm also looking into adding a traffic shaping rule. Image attached. Feel free to provide suggestions.

Where is the insufficient bandwidth? You should have alarms that tell you if it's internal, so mentions a particular phone. Or external and tells you the SIP Trunk group number.
