IP Office Network Broadcast 2

[RafaB]

A client has noticed that on their network their IP Office 412 is sending out a broadcast. This broadcast is sent right across the network and my assumption is that it may be looking for IP devices or telling IP devices it is there in case they need the IPO. The problem is that their network is not particularly quick and this broadcast goes across the network every couple of seconds and is un-explainable and therefore may be the root cause fo their network being slow. I have assumed that it is not looking for the Voice Manager as this has a fixed IP address. Does anyone have any suggestions (or need more info).

Thanks in advance.

other things that can cause broadcaset traffice are Licence requests & time server requests
make sure that both of these are set to a fixed IP.

updates for Phone Manager are also sent using broad cast.

Just checking whether it is the phone manager updates. That is a reasonable explanation. However I thought that these may be sent via a unicast to selected machines rather than a broadcast to all ?

call connection details are probably sent to individual Addresses ( I have never actualy bothered to test) but user status updates, as required to update the display on internal speeddials & blf keys are sent as broadcast.

this is a good thing other wise may unicast msgs wouuld be needed when 1 broadcast will suffice

never bothered to test". Us too, we don't really see why this is seen as an issue.

"this is a good thing...." - Very good point

There are quite a few broadcasts that go on.

- When started, the default is to broadcast for a voicemail systems. You can stop that by switchign voicemail type off or if you have a voicemail server setting it IP address in the IP Office config.

- RIP is broadcast to x.x.x.255, that can be turned off if not being used.

- As others have said, user status messages are also broadcast for apps such as Phone Manager and Soft Console to pickup. I don't think this can be stopped but it should only occur when a user status change occurs, contiuously every few seconds sound like a very busy system.

Launch Monitor, click on the clear all tabs button down below (and confirm) then go to the interface tab and click on tab set all button. You will then see all activity on your network with handy dandy explanations of anything related to the IPOffice.

One thing I have noticed will cause a broadcast every few seconds is if you have h.323 trunks programmed on your system (perhaps when experimenting) but no endpoint for them.

Broadcast is standaard comming from the licene-server,time-server and Voicemailserver.

Sets a specific address for the Control Unit's time server requests. Blank or 0.0.0.0 means default operation as above. 0.0.0.1 disables time server updates.

Voicemail IP Address : Default = 255.255.255.255
This is the IP address of the PC that is running the Voicemail Server or Voicemail Pro application.

If set as 255.255.255.255, Control Unit broadcasts on the LAN to see if it can discover the Voicemail Server. If set to a specific IP address, the system connects to the Voicemail Server running on that specific IP address only.
