Just want to correct that softphone works not with “PortaOne server”, but with PortaOne server PortaSIP, which is part of solution platform for ITSP called PortaSwitch.
I have downloaded this SDK and compared it with another SDK called Ozeki VoIP SIP SDK (voip-sip-sdk.com). The usage and functionalities were quite similar. Both of them can be easily used. However I found that the PortSIP VoIP SDK reaches the functions via DLLImport whereas Ozeki SIP SDK is a pure .Net solution. To sum it up I would prefer the Ozeki SDK because thanks to .Net it is more flexible and could easily implement it into my application.
