In VoIP world, a dialer or softphone is a software program for making telephone calls over the Internet using a general purpose computer, rather than using dedicated hardware. Often it is designed to behave like a traditional telephone, sometimes appearing as an image of a phone, with a display panel and buttons with which the user can interact. A dialer or softphone is usually used with a headset connected to the sound card of the PC, or with a USB phone. It can make VoIP calls. iTel dialer support H.323, SIP and IAX2. It has echo-cancellation, NAT support and VPN support. As every dialer supports VPN, so we can have a secure communication. It can make multiple simultaneous calls from the same PC. It is also integrated with online billing.

iTeliAX2Dialer has been developed using the powerful IAX2 protocol or Inter-Asterisk Exchange Protocol. This has been specially designed for the region where support behind NAT or firewall is required.

• If your challenge is to pass through any firewall, then iTel-iAX2-Dialer is the solution. This dialer can challenge any barrier imposed by internet firewall to your VoIP business
• iTel-iAX2-Dialer requires very low bandwidth comparing to other dialers on other protocol like SIP or H323 or VPN. (IAX2 supports trunking, multiplexing channels over a single link. When trunking, data from multiple calls are merged into a single set of packets, meaning that one IP datagram can deliver information for more than one call, reducing the effective IP overhead without creating additional latency. This is a big advantage for VoIP users, where IP headers are large percentage of the bandwidth usage.)
• A call through iTel-iAX2-Dialer usually does not have the risk of over billing for hang call. IAX 2 protocol uses very clear layer 2 and layer 3 separation. So both signaling and audio have defined states and are robustly transmitted in a consistent fashion. As a result, when once end of the call abruptly get disappear, the call used to be cut in a timely fashion without creating any hang call
• IAX doesnt need the support of stun server where as SIP needs this for resolving public IP if the client is behind NAT server.
• Its voice quality is excellent as it uses jitter buffer to avoid distortion. It can also work intelligently if the bandwidth is very low.
