SPA Registration Problem - Causes 3 way conf

[slantyyz]

Has anyone experienced this:

 

When an SPA3000 registers during an active call, Axon creates a 3-way call to the voicemail (we use IVM). All parties can hear the default greeting.

 

Because the Line 1 and PSTN register one after another (1 second difference), it's hard to identify the true culprit, though I suspect it is the PSTN registration.

 

Example:

 

My Sipura shows registrations for Line 1 @ 12:28:16, PSTN @ 12:28:17, and IVM picks up the line at 12:28:30.

 

The Axon log shows the external number calling the voicemail, ie:

12:28:30 Call sip:######### -> 199 (199 is the default extension for our IVM)

Since registration occurs at preset intervals, I can predict when this problem will occur, but I'd rather not work around the interval and eliminate the issue altogether.

 

Any feedback is appreciated.
