MBG disconnecting calls after around one minute
« on: January 22, 2013, 08:40:10 AM »
I am at the end of my rope here...Teleworker phones are intermittently dropping calls after around one minute. MBG version 7.1.21.0, MCD version 5.0 sp2 PR2.
Seeing the following in the event logs:

MBG  one-way audio  08:00:0F:47:D7:23  Major  Mon 21 Jan 2013 15:45:30 CST loss of rx stream from SS for 5008ms
MBG  one-way audio  08:00:0F:47:D7:23  Major  Mon 21 Jan 2013 15:43:32 CST loss of rx stream from SS for 5018ms
MBG  one-way audio  08:00:0F:31:74:D3  Major  Mon 21 Jan 2013 15:01:51 CST loss of rx stream from SS for 5017ms
MBG  one-way audio  08:00:0F:47:D7:23  Major  Mon 21 Jan 2013 14:38:27 CST loss of rx stream from SS for 5005ms
MBG  one-way audio  08:00:0F:31:74:D3  Major  Mon 21 Jan 2013 14:15:37 CST loss of rx stream from SS for 5005ms
MBG  one-way audio  08:00:0F:33:5D:9E  Major  Mon 21 Jan 2013 13:43:30 CST loss of rx stream from SS for 5015ms
MBG  one-way audio  08:00:0F:32:0B:53  Major  Mon 21 Jan 2013 13:34:35 CST loss of rx stream from SS for 5009ms
MBG  one-way audio  08:00:0F:31:74:D3  Major  Mon 21 Jan 2013 13:04:22 CST loss of rx stream from SS for 5007ms
MBG  one-way audio  08:00:0F:3F:F8:D5  Major  Mon 21 Jan 2013 12:55:01 CST loss of rx stream from SS for 5012ms
MBG  one-way audio  08:00:0F:3F:F8:D5  Major  Mon 21 Jan 2013 12:30:46 CST loss of rx stream from SS for 5016ms

Has anyone experienced this?
It seems to report as one-way audio, but on a few test calls there has been no audio in either direction.

Yes.  I've experienced it.
Firewall.

What firewall do you have?   Are you in DMZ mode?

I have also seen this behavior, but caused by the router on the far-end, but still a firewall issue.

If this is happening on phones at just one site but other sites are fine, check the router on the far-end, depending on the model/configuration it might be as simple as just turning off SPI.

If multiple locations are effected, it is clearly something on the Teleworker end. Although I have gotten this to work in DMZ mode, clearly the most effective, efficient, and least troublesome is in in Gateway mode with one NIC directly on the public network.

Found the issue. It was the firewall, a rule was missing so outbound packets were being dropped.

Did you beat your firewall admin?   >:(

Pretty much every audio problem on teleworkers can be traced to programming in the firewall ( if the MBG is setup correctly ). Least that's my experience.
