I have a receive-only VoIP account with a small-time company in Poland. There isn’t much in the way of support or features, and sporadically offline, but okay. I bought a local DID number from it.
What FOSS Windows or Linux software might I be able to use on a virtual server that
-
has the ability to auto-answer calls after a timeout of N seconds (or X rings) because I am not picking up the line elsewhere, playback a greeting and record a voice mail?
-
Optionally, forward the recorded voice mail to an email address.
Something much, much simpler than having to setup an Asterisk server. (However if you see a very focused how-to that applies, or with FreeSwitch or similar, please share.)
Better yet, is there a free cloud-based solution somewhere, sparing me the need to deploy this software on my own, having a PC always on?
Maybe some indirect way using, e.g., IFTTT, such that supplying my SIP credentials in some (web?) client will trigger an email + audio file attachment?
