I added my number to e164 last night at about 7pm. I clicked to reschedule the verification call becuase I thought I had missed it (in fact it was the ring it gives to test the sip address). The verification call eventually came at 4am. I was NOT amused.
particularly as the baby upstairs then kept me awake another hour! Would it not be possible to choose the time of the call, even it was to choose a slot for the next day? When I did it again now, it called back in 5 minutes so better.
