Calls billed twice?

Why do some calls appear twice on my bill, with the actual time (3:48) and a rounded up time (4:00)? I'm not being charged for them as I'm under my limits, but it's just got me concerned about what I'll get hit with if I go over them. It "looks" like I'd be billed twice...

Is the line number the same for both? If so it's called call splitting, and is used when calls overlap two billing categories. i.e. call starts before 7 and continues past 7, or call is long distance and one line shows ld charges while the other shows airtime charges.

Thanks, Timo. From what I can tell, there isn't really any rationale. It's for calls any time of day, not just at category changes. It's largely on long-distance (incoming or outgoing), but then it also includes a message retrieval call while at home (but not all), and doesn't include a message retrieval call when I was on the other side of the country. Again, didn't result in any charges at this point, but I just hate it when bills are so cryptic you can't figure them out.

If the entire duration of the call is both fully airtime chargeable and toll chargeable and these durations are exactly the same, the call is not split.
If the entire duration of the call is both fully airtime chargeable and toll chargeable and these durations are different, the call is split into a chargeable airtime line and chargeable toll line.
The durations may be different because the Airtime may use per-second rounding whereas the Toll may use per-minute.
This would only apply to rate plans with Per-Second Billing (prior to February 2/2012).
The Airtime and Toll durations are also slightly different on US Roaming calls.
If there are any elements of included air or toll or free airtime, the call is automatically split into all the different duration types associated to that call including chargeable (airtime or toll), included (airtime or toll), or free airtime).

I've just seen a duplicate call in my usage records as well: Two entries for incoming calls from the same number, at the same time, same duration, no splitting, not toll chargeable, etc. Why? It doesn't make sense.
