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. iTel-iAX2-Dialer: Challenge to any Barrier for Your VoIP Business TOP
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.Important Features of iTel-iAX2-Dialer
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. iTelSIPDialer TOP Features of iTelSIPDialer
