Asterisk to PSTN

Postby infinite3219 » Tue Oct 13, 2015 11:07 am

Hi,

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 http://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.

Thanks,
Terry

I believe the only legal way of connecting Asterisk to Skype is by using Microsoft's SIP gateway to Skype, which I believe is chargeable.

Digium make a range of PSTN line cards for PCs. That was the original use of Asterisk! These are extremely compatible with Asterisk.

You can also use third party SIP to PSTN gateway devices.
