SIP protocol is regarded as the industry standard for VoIP. A number of telephone companies, IP phone manufacturers and virtual IP based PBX systems have been using this protocol for connecting calls. On the other hand, Skype has been using a proprietary protocol and whenever one wants to call from a SIP based VoIP service to Skype, one requires an adapter which acts as a gateway so that calls be made as SIP and Skype are not interoperable.

NCH Swift Sound has come with Uplink which connects SIP based voice calls to Skype and it works in both directions. It can be easily configured and used. Once the software has been installed, go to the options to give the path to Skype executable, enter SIP service setting and dial options when Skype calls SIP and vice versa. If configured in the right manner, it works perfectly and provides a good voice quality.

These were the features found on the NCH website:

Connects both incoming and outgoing calls to the Skype network.
Can be used to make SkypeOut calls from a SIP device or SIP PBx.
Can receive SkypeIn calls and direct them to your SIP extension.
Fully complies with the RFC3261 for SIP signalling.
Quick and easy operation
