I have a use case where I want to call PSTN numbers and do text to speech via Asterisk. I’m looking to do this primarily for Singapore. Does anyone have any recommendations on the VoIP (SIP) providers I can connect Asterisk to for this capability? It seems like Skype for Business may work, but it’s unclear if there is a problem here because Digium’s website says the agreement ended, but maybe that applies to Digium supported products, not for open source Asterisk.
Does anyone know more about this Skype for Business integration with Asterisk or alternate providers that may work with Singapore phone numbers? I found this Skype integration document asteriskdocs.org/en/3rd_Edition/ … 91565.html. If you have any tips on if that is the most recent and if it works, that would be great.
