Hiya,
I'm a linux systems admin with 15+ years experience, and I've seen such an issue recently and solved it for that client too. I'm guessing you're using vicidial or a similar front-end.
My bid price is based on my spending up to 3 hours on this. If the problem is quickly solved, you may feel free to use up some of the remaining time on general advice/etc.
Even if the problem is not what I immediately suspect it is, I'm a specialist in Linux security and I'm confident I can get to the bottom of it and sort it out for you.
I'm a member of the Association Of Independent Computer Specialists (AICS) and bound by their Code Of Practise
