A packet becomes unroutable between two sip elements if one of the networks uses private IP address range and other is in public IP address range.Stun is a mechanism to enable this border traversal.There are several Wi-Fi enabled mobile phones and PDAs that have pre-installed SIP client software, or are capable of running IP telephony clients, including most smartphones.Analog telephone adapters provide an interface for traditional analog telephones to a voice-over-IP network.They connect to the Internet or local area network using an Ethernet port and have jacks that provide a standard RJ11interface for an analog local loop.Another type of gateway device acts as a simple GSM base station and regular mobile phones can connect to this and make Vo IP calls.For voice and media encoding, a variety of coders are available, such as for audio: G.711, GSM, i LBC, Speex, G.729, G.722, G.722.2 (AMR-WB), other audio codecs, and for video H.263, H.263 , H.264.User interface software controls the operation of the hardware components, and may respond to user actions with messages to a display screen.
Some Vo IP phones also support PSTN phone lines directly.
Skype is a Vo IP service, which uses the Internet to allow people to make and receive free voice and video calls online for free or for cheap.
Vo IP has during the past decade showed the way to communicators how to go around the expensive PSTN and cellular plans and make international calls for free or cheap.
There are alternate mechanisms for traversal of NAT, STUN is just one of them.
STUN or any other NAT traversal mechanism is not required when the two SIP phones connecting are routable from each other and no firewall exists in between.
It has been the most popular Vo IP app and service for many years, although it is no longer so today. While in the past you needed to take particular care of the minutes and seconds you spend speaking on international calls, you no longer need to bother about that now.
