I bought a Rolls PI9 Phonepatch II. I did as instructions said.

1) Hooked with filter line into phone in.Then ran another line to telephone.Then audio out to PV10(board)

When I cue up the board the levels go in the red. Also the phone rings constantly when Rolls is open(on).

I bought another filter for phone(internet) but still the same problem.
When I unhook the adio out cable, I can use the phone.

Thanks
Rob

PI9 PhonePatch II
- RCA and 1/8" (3.5mm) Inputs
and Outputs
- RJ11 Phone and Line jacks
The PI9 is a passive device for
connecting a phone line to an
audio system or vice versa. Handy
for phone interviews, broadcast, or
laptop presentations with a remote
phone signal.
INRODUCTION
Thank you for your purchase of the PI9 PhonePatch II. The PI9
takes a signal from a standard telephone jack and,via transformer
isolation, connects to a pair of RCA jacks, or a stereo 1/8"
(3.5mm) jack. The isolation keeps the output signal separate from
the telephone line, and will not keep the line open unless the
HOOK switch is in the ON positin as described later in the guide.
Applications for the PI9 include broadcast, conference
rooms, phone training, laptop presentations, or wherever a phone
conversation needs to be recorded or heard over a PA system.
The PI9 also works for putting audio onto a phone line. However,
you must ensure the signal level is no hotter than line level (+4
dB) or you will get distortion on the phone line.
WARRANTY
For information on the Rolls One Year Limited Warranty, and to
register this product, visit our website at www.rolls.com
DESCRIPTION
INPUTS: 2 ea: Standard RJ11 phone jacks.
AUDIO LINE: Stereo RCA, 1/8" (3.5mm) jack
ON/MUTE switch: Connects or disconnects the Phone/Line jacks to
the transformer and the Audio output. With the switch in (ON) the audio
is active. When the switch is out (MUTE) the audio signal is muted.
CONNECTION: Refer to Figure 1.
Connect a standard telephone cable to an active telephone line,
and to the PI9 Phone Input. To pass the signal on to another
telephone, connect another standard telephone cable from the
PI9 Line jack to a telephone.
Connect either a stereo RCA cable, or stereo 1/8" (3.5mm) cable
to an AUDIO LINE output jack.
Figure 1.
HOOK: OFF - ON
An option on the PI9 is the ability to select whether or not
the unit will hold a line open. A line being "held open" acts
like a telephone is off the hook. ON is for the line to be left open
and OFF is when the phone is hung up.

I have tried most of these "cheap solutions" to getting a phone line into the station and all of them seem to be marginal at best. Look on ebay and find yourself a decent phone hybrid. I paid 150 dollars for a Gentner Hybrid Coupler and have not looked back at all. I have it sent into my mix board so I can control different audio levels guests and what not have and I even can EQ/Compress/Expand the thing. I have had great success with this little box and crummy results with things like skype and such. I look at it like this.... If you can spend what a few hundred dollars on the software we use here IE sam broadcaster whats another few hundred to sound good? You get what you pay for thats for sure.

After trying this myself, two major issues:

-The callers had a very hard time hearing me - lots of outgoing distortion/breakup at any level
-The lag brought on by their cel phone and my cel phone was about two seconds

I'm about to try a little more elaborate system since I have exceptional internet service where I am. We already have a Google Voice number for our request/comment line. We hooked up an OBi110 and an old school wired desk phone. The OBi allows you to use your Google Voice number as a de facto landline. Now I'm waiting for the final piece - a JK Audio Broadcast Host hybrid, which you can get for around $300 used if you search hard enough. This should strike the balance of good outgoing and incoming quality - and the quality of the internet connection should eliminate my part of the lag problem. When I get it all up and running, I'll report back here.

http://www.behringer.com/EN/Products/802.aspx Behringer mixers such as this one work great for this type of application. Not a shack fan myself. Their prices are too extreme for what you purchase. Personally, I use a place locally called Texas Electronics for cables, splitters extensions etc. My suggestion is look up a local electronics supply and frequent regularly. One of the highlights of grabbing parts is shooting the bull with the fellas at the shop. They are truly knowledgeable and offer solutions that one may not think of on their own.

I hope I am reading this thread correctly. I want to broadcast callers on the air using their telephone.

You would be putting them on the air using YOUR studio Phone. Using the phone of someone at a physically different location would be pretty complicated and will only work in very rare cases.

An Irig is a cheap solution that keeps the call sounding no worse than what you hear on regular radio, just do a quick mix-minus and 3 cables and a cellphone and you can do phone or Skype interviews cheap and with good quality, especially with Skype. You can get fancy if you want, but at that point you may as well get an arrakis board with a phone module if you're going to go all out and skip the middle level stuff like JK Audio all together.
