Junction Networks' OnSIP Hosted PBX users now have four ways to make/receive phone calls. Firstly, you can use your SIP-based soft phone/hard phone. This is how the majority of the calls are made today. You simply dial your phone. Secondly, you can use our "Click to Call" Firefox add-on. Then, any phone number listed anywhere in a WWW page is 'clickable'. When you click on that number, we place a call to your desk phone. Once you answer, you hear "Outside transfer" and then the 'ringing' of the phone for the phone number you clicked on. Thirdly, use our "Click to call back" Ajax API, you can place some HTML into your WWW page which displays a form for entry of a phone number. The user puts their phone number into the field. When they submit the form, you receive an immediate phone call, again with the prompt of "Outside Transfer" followed by the ringing of the phone for the phone number they entered. We now have a fourth way to make phone calls and the flexibility of this application is what excites me. I just used it this morning to call a SIP address directly because calling a SIP address from my SIP-based desk phone is laborious. Log into the OnSIP Hosted PBX user portal (as a user, not as an admin, if you are an admin you have to go to your 'user' page directly by editing the URL to: https://admin.onsip.com/users/xxxx/info/, where xxxx is your User ID number.) Now, at the top of the portal is a link to "Place a Call". Clicking on the link creates a "call box" where you can type in a phone number or SIP address. Click on "Call" to place the call. Immediately your desk phone will ring and you will hear "Outside Transfer". You then hear the ringing of the phone on the other end. I love it.
