## Description

With all the changes being made to the phone lines these days it seems that our beloved rotary phones may become non functional. Well not with our automatic pulse to tone converter. This snazzy little unit will AUTOMATICALLY convert your traditional pulse dial to a modern DTMF tone. Simply dial your phone as you normally would and the pulse will be converted and recognized by your modern phone line including many VOIP devices, and Cable TV Phone Adapters. There are an almost infinite number of phone and network combinations. We can not guarantee that this converter will work with your specific setup. Key Features of the Rotatone EXT Easy to install, just plug it in and start dialing Requires no modifications to your old phone Supports all standard rotary phones Converts 0-9 Pulse/Decadic dialing to DTMF tone Allows you to dial * and # on most rotary phones Six speed dial memories Last number redial feature Needs no batteries, no external power supply Advanced microprocessor control for accurate dialing Suppresses dial pulses on the line to stop double dialing faults Not effected by incorrect line polarity Configurable for non-standard dial layouts (Sweden, New Zealand) Does not interfere with ringer operation Supports a wide range of international telephone line voltages and currents Specially designed to tolerate low line voltages found on many VoIP boxes and ATAs

Review: It works! - This works exactly as described. I'm not an expert, just did some research on wiring diagrams for these old rotary phones to get them to work. This will work with a new Comcast Xfinity service and XFI devices. Hopefully the video will help as I am not an expert and I don't do videos but I try to be as clear and concise as possible. I feel this one needed some explanation as well as some of the problems you might run across while you're trying to bring these old phones back to life. Worth the effort for all the nostalgia these phone bring back when they are working again! Disclaimer...that is not my phone number on this phone.
Review: Works great. Plug it into the wall, not the phone - Works great. I have a rotary phone plugged into a cellular base station that I bought from Walmart. Works fine. But first I plugged it into the back of the phone and it didn't work. Then I plugged it into the base station and it worked great.

## Questions & Answers

**Q: I see where you previously answered that it doesn't work with google voice and obi, but found on obi forum where they have used your converter to work**
A: Works pretty well with obi202. Obi202 only gives you enough time to dial about 7 digits however. The product is not perfect it doesn't use any power from the wall it only works off of line power available. The slower you dial the better it works. This conflicts with the amount of time available to dial a number on obi202. I guess long distance would not be possible without a secondary touch tone phone. On the obi202 setup page you will find you can preset your area code so it doesn't need dialed every time. If you do this then you only have to dial 7 digits usually. I love both products but you probably will need a touch tone phone. It does render an old phone usable maybe just for nostalgic reasons but the phone will dial out. I tried other pulse to tone converter that didn't work this seems to be the best option. It would be handy if the folks at obi202 could extend the amount of time with a software change that a person has to dial a number. I hope this helps you it's all I really know about it. I found this from trial and error. As far as Google voice goes, I'd say it's identical to the other service's on how this product works. 😀

**Q: How would I hook this up to a rotary wall phone? Is it necessary to attach it  at the wall, or with the comcast box?**
A: You attach it to the comcast box and then plug the phone cord in to it.

**Q: I went from verizon dsl (my old phone worked) to verizon fios and my old phone does not work. has anyone had experience with this with fios? thanks**
A: NO! this unit does not work with FIOS. On old 350 sets.

**Q: Will this work with a rotary phone replica?**
A: This unit gives a pulse dialer the ability to send DTMF tones. Most of the rotary phone replicas already send DTMF tones and do not need this. This unit converts pulses to tones. Any phone that dials in pulse will work with this.

### ⭐⭐⭐⭐ Worked great
*by R***R on September 28, 2018*

I have it hooked up to a Verizon home base. Works fine, just had to let it sit plugged in for about 15-20 minutes before it would dial out. On a side note, I forgot how laborious it is dialing a rotary phone.
