Cell Phones and VoIP
When I walk into my office, my cell phone instantly links with my office phone. As long as I am in my office I never pull my phone out of my pocket. Incoming calls ring on the desk phone.
I just love this connectivity. It’s simple. It’s automatic. Its seamless.
I can also place phone calls on my desk phone and then just walk away from my office and the call transitions to my iPhone. What surprises me is that I have no app on my iPhone to do this.
How is this possible?
I use two methods:
At work, we use the Grandstream GXP2160 SIP phone. It’s a 6-line SIP phone. But line 6 is special: It can link to an Android or iPhone via Bluetooth. The integration is good: You can place and receive calls on Line 6 and they actually go through your smartphone. You can even scroll through the phone book on your cell phone using the Grandstream desktop phone. (See related post).
This device links to your smartphone via bluetooth. It then presents a standard analog phone line, just like a SIP ATA would.
So, I cut the cord to my landline company. I installed the Xtreme Tech Xlink BTTN bluetooth link (in the link above.) I just plugged its analog line into a wall jack in my home.
Now, when I get home I set my phone down on the nightstand and plug it in to charge. It automatically links up to the Bluetooth ATA gateway and my calls go to the wiring inside of my home.
When a call comes my home phones ring and I answer the call. When I want to make a call I lift my handset and get dial-tone. My dialed call then goes out via my cell phone. It works great. And, it lets me use my designer phones in my home. (The device even supports rotary/pulse dialing!)
Not cool enough? Dial ## on the analog phone and you can dial using Siri.
I think of this device as a “Bluetooth ATA”.
It’s pretty cool. It works like a champ.
