International calls drop after two hours
Posted: Sun Feb 21, 2021 8:27 pm
Most of my phone calls are shorter than two hours, so it took me a while to notice a pattern, but over the last year, any international calls lasting longer than that have consistently dropped without warning, after almost exactly two hours, (give or take a few seconds). Starting last month though, they started dropping after four hours, instead of two, so that's an improvement. I only had one domestic call that lasted over two hours over the last year, and it didn't drop unexpectedly, but a sample size of one is not really a pattern.
The behavior is predictable enough, and the duration non-random enough to suggest there's a specific explanation. I confirmed that my prepaid account still had a positive balance, so that's not the reason. I don't think that either of my handsets (an HD3, or an old 900 MHz cordless phone) are causing the dropped calls, because I'm still able to use either one to redial the number, and re-establish the call.
I would appreciate any explanations, suggestions, workarounds, or any other helpful comments.
Thanks,
