A lot will depend on how you store them. I always prefer unix timestamps 
(ie. 32-bit integer) but if you've got them as strings, then there's a 
million and one ways to represent them unless you force a certian format - 
even then, fif you're dealing with the international market - is is 
day/month/year of month/day/year. (9th of November anyone?)

There is a standard and I've forgotten the name of it, but it's

   YYYY-MM-DD HH:MM:SS

as a string - and what's good about that is you can sort it and compare it 
relatively easilly. (it's the datetime format that SQL uses)

What's the output technology? mISDN is the only one I've had issues with 
and that's mainly been on the input side. Never had an issue with anything 
else. (My least the punters haven't reported any problems - maybe they 
just don't call IVR systems!)

You might want to check the settings on the phones too - make sure you're 
using rfc2833, then it should stay out of band at least internally.
