Hello,
I've read that the # of maximum callers is 15.
Since there are "Beta" version coming out will these be able to handle 15 simultaneous callers too?

A short answer is "yes, after a software update".
A longer answer is that hardware supports dual-TRX operation, but software support is not there yet. We might be able to fix software before we ship beta units, but even if not - you will be able to get the software update later. Also keep in mind, that UmTRX should be able to run multi-ARFCN OpenBTS and in this case it'll be able to handle much more calls. We haven't tested this mode of operation extensively yet, but theoretically we might be able to support 14ARFCNs (2x7ARFCN) which equals to (14*8-1)=111 calls. At this scale you're most likely limited by computing power of your PC rather then UmTRX hardware. Whether we could get UmTRX in Multi-ARFCN mode through certification or not is still a question, but it should be fine for lab testing.

I recently posted about multicarrier operation with UmTRX.

More extensive testing remains, but 15 calls in a lab environment does not pose any significant issues. Larger scale operation - with power amplifier and /or 50+ simultaneous users - remains to be tested.
