SIP registrations not clearing down on MBG

[Belsden]

Hi all,

MGB version 9.1

I have an issue where SIP registrations are not clearing down on an MBG within the MiCollab platform.

Scenario: Customer had an issue registering the Konftel SIP device in the first place, I sorted this out for them whilst sitting at a desk within the office (all tested okay). I then plugged the Konftel in the conference room and tested with one way speech. Looking at the MBG registrations there were 2, as the network has DHCP, therefore is registering twice for each IP and sending the voice path to the wrong IP, hence one way audio.

Firstly, is there a way to remove the SIP registrations without rebooting?
Secondly what settings do I need to check to clear the SIP registrations down?

Things I have checked:
1) SIP capabilities timers

Subscription Period  3600
Subscription Period Minimum  300

Will i need to check keepalives?

I know that some of you may say, just set a static address, but customer does not want this.

Many thanks for any help

no need to have static ip's, dhcp is used all over the place.

but for sip, the sdp from the sip device tells MBG where to send audio, unless the sip device is behind NAT, then you need teleworker licenses to get audio to work.

If this is a pure lan setup, look in the mbg logs for the sdp from the sip device and verify that it contains the correct ip.

Thanks dilkie, i'll take a gander at the logs and see what's occurring

Sorted the issue. I changed the keep alive options to "always" instead of "behind NAT only" and it drops the connection fine
