We have VVX 411 running 18.104.22.1685 and when you put a call on hold, it drops after 30 seconds.
If the call is answered using the Skype client, the call will remain on hold longer than 30 second...I had a call on hold for 1 minute and call did not drop.
Next steps? Anyone else seeing this?
This is usually RTCP issue.
You can see it blogged about here:
Thank you for this information but it did not fix the problem...my trunk configs are correct but calls still drop after 30 seconds. I was informed by the support vendor, ScanSource, that I need to open a case with Microsoft about this issue.
