BLF & Hunt Groups

Hello,

 

We have 6 Grandstream GXP2010 phones (with an extension each) connected to PBXNSIP v2.1.10.2472 . Everything is working great, except for some strange issues with BLF lights when a Hunt Group is ringing. Basically we have set up the 6 phones so that the BLF indicators on each phone show the status of the 6 extensions - this works successfully for a direct call to an extension, but if all extensions are ringing (they are all in a hunt group) then the BLF lights go crazy - sometimes they all flash (which is correct) sometimes one line flashes, sometime two etc, and it is different on all phones! Even worse is that if the call connects or terminates, then some of the lights stay flashing until the phone is rebooted...

 

I have tried reducing the watched extensions to two on each phone and switched to TCP for the transport - but it has made no difference.

 

I have enabled full logging and with the direct line ringing you get a "notify" message going to all phones from the ringing extension with XML content showing the connection details. The same with when the call terminates. When you ring the hunt group I would assume I should get a message from each extension in the hunt group to all other extensions - but this doesn't seem to be happening (although the log gets pretty full so I can't say 100%), so I don't know if PBXNSIP is not sending out all the messages.

 

Has anyone seen a similar problem?

 

Thanks

A hunt group is definitively a "stress test" to the phone. It receives a large number of messages in a short period of time. Maybe what you can do it log only SIP packets to/from the IP address of the phone and write the log to a file. Then we can find out if the messages are going out as they should.

Thanks for the suggestion - however I'm having problems setting the logging. I have added the IP address of one phone (192.168.5.88) to the Log Watch List (IP), set the Log Watch List to 9, enabled only "Log SIP events" and "Log SUBSCRIBE/NOTIFY", and set the log level to 9. However the log is still showing information for all phones (and also other events such as REGISTER which are not selected in the settings). I Have restarted the PBXNSIP service but it doesn't make any difference. Help - what am I doing wrong??
