| ThinAir Communications SIP Trunking service is a scalable VoIP solution providing ISPs and resllers a VoIP to PSTN gateway solution. We allow you to connect to the ThinAir Communications SIP Proxy via any high speed broadband connection (ie, our IP Transit service or any other public Internet service). We'll allocate nationwide DDIs and tollfree numbers where available in bulk which you can then manage and allocate to your end users. ThinAir Communications will originate calls to these access numbers from the PSTN and route these calls to the appropriate SIP Trunk (usually a dedicated IP Address or domain name). We'll offer competitive terminations rates for national and international locations as well as our BIG BACK YARD service which has become popular with both our domestic and corporate customers. Call quality is often superior to traditional PSTN landlines, utilizing audio codecs such as G711 and G729. |
