Now that development of good SIP (https://en.wikipedia.org/wiki/Session_I ... n_Protocol) applications has once more received increased attention, open source SIP clients again become a telephony alternative to closed-source Skype.
Hence I'd like to discuss in this thread experiences with SIP providers that
- offer connections to landline and mobile phones,
- provide Direct inward dialing (DID) phone numbers (i.e. "normal", "real" phone numbers).
- https://www.callcentric.com/: U.S. provider. Has an imprint on its website. Apparently no contact e-mail address on website. Offers "Fax to E-mail" service.
- https://www.diamondcard.us/: Provider headquarted in Thailand (formerly USA). Contact e-mail address on website. Supports various open source projects. Support wiki. Apparently no "Fax to E-mail" service.
- https://www.localphone.com: British provider. Friendly website. Apparently no contact e-mail address on website. Apparently no "Fax to E-mail" service.
- https://www.voip.ms/: Parts of their website don't seem to work with the Pale Moon browser. Apparently no contact e-mail address on website. "Fax to E-mail" service restricted to U.S. and Canadian DIDs (cf. https://wiki.voip.ms/article/Virtual_Fa ... ax_Service).
Greetings, Joe
