SIP stands for Short-IP Protocol. IP telephony and Internet connectivity are defined by set protocols, amongst them Session Initiation Protocol (SIP). Session Initiation protocol is an efficient communication protocol for controlling and signaling multimedia video communication sessions enabling people to share information over the web via their personal phones or computers. Video or audio conferencing is an increasingly popular way to carry out business or personal communication over the Internet, which is why SIP is so beneficial.
Phone systems are made up of several components, some of them are known as telephones, which can either be fixed lines or mobile phones. A phone dialer can be used to dial a phone number for which no number is available in a phone book or any other phone directory. These days, there are several services available for free on the Internet that allow you to call numbers for which no name is available.
Using a sip dialer is relatively easy, as all a user needs to do is find a website that offers these services. Some of these websites also offer support for certain networks such as GPRS or EDGE. Once a user has found a website that provides services for free, he can log in and enter the phone number or name that the site is providing for free. If the information provided matches the information of the listed number, the website will prompt the user to pay a minimal fee to access the full list of numbers.
Using a service like this, a user will be able to dial a phone number from anywhere in the world without having to change his phone carrier. All calls from the users’ mobile phone will be converted into text messages to enable the user to see the message on his mobile phone without having to look at the phone itself. This saves a lot of time and money and allows the user to talk from anywhere.
There are various features of SIP phone services that a user may want to explore. For instance, if the website provides features that allow the user to manage multiple lines, this is helpful as it allows the user to maintain multiple lines simultaneously. It is also beneficial if the website provides services to manage multiple extensions of the same number for the same number.
If the user finds the website is providing too many features, he can try another one. However, it is recommended to check out the site before proceeding. as not all websites provide the same features or services. The website should be user-friendly, so that he can be able to navigate through the system easily.
Another feature is to have a button on the website where the user can enter the phone number for which he wants to make a call. After selecting that number, the user can choose between two payment options: a one-time or recurring payment. The payment option enables the user to make a single payment per call or he can make regular payments for a series of calls.
Some sites also provide a facility of automatically dialing the number when the user dials a phone number that is not the registered phone number. When the user presses the phone button, the website will dial the number and send the message directly to the caller after sending the message to the caller ID. If a user wants to call the number back, he needs to enter a new phone number in the phone number dialer and press the call button again. This saves both the user and the website from having to enter the number repeatedly.
