Client claims T26p is autoanswering

[rebuke]

Just to add to this, I've got a client reporting the same problem intermittently - they're using T26Ps running firmware 6.70.0.141.

I've not got any traces etc, as the issue is not easy to reproduce 'on demand', and capturing traces permanently results in lots of disk space usage, however if there is anything that can be done to help diagnose this, please let me know, as it's a potential security issue if the user doesn't notice and is having some confidential discussion near the phone etc...
