Reading dmp file?

[myname24]

A user's 3CX softphone keeps crashing while she's on a call. I have quite a few dmp files but they're in binary. What can I use to look at them and try to determine why it keeps crashing? 10 other users in the office have no issues. They're all running the same version and applications on their computers.

Hi there,
Which version of 3CXPhone are you running ? Is it provisionned using a welcome email ?
Is the machine fully up-to-date on windows updates ? .NET ?
If any antivirus/antimalware/http proxy/VPN on the machine please review http://www.3cx.com/blog/docs/3cxphone-presence-self-help/
