While tracking call events via detailed presence subscriptions, we're observing unexpected international caller prefixes in calls directed towards our sandbox account numbers.
In particular, calling from my moble, in Portugal, with a +351 international dialling prefix, inbound call events are shown from "+1351...", where the remaining digits are indeed correct. It's as if RingCentral is prepending the +1 prefix to all external inbound caller IDs.
Maybe this is somehow related to how our sandbox account / users are setup?
Can anyone please point out what we're probably missing?
Thanks in advance.
