Two extensions dropping calls 99% of Abandoned calls

[Espeed3]

Recently we have had an issue with dropped / abandoned calls for two users.
They are not requesting the call to disconnect but the logs show that their softphone is. Our logs are full of Dbg|MYPHONE: _DAC([115 RequestDropCall yet the users is not even getting a chance to answer the call. Most of the time the call gets dropped while the IRV is playing and has not yet connected to any extension. Any thoughts?

Regarding your question, when you see 115 RequestDropCall in the management console log, this indicates that someone has dropped the call from their webclient/dektop app. Check further down the same lien for which extension did this, for example, here, extension 000 dropped the call from their webclient:
MYPHONE: _DAC([115 RequestDropCall]) - 00:00:00.0769851 - from 000[1xxxxxxxxxxxxx]@10.x.x.x. Requests:1 -> 0 (traceid=00000000),
Along the same line, you will also see the IP address from where they were connected when they dropped the call.
