I've really appreciated all the posts here and we have used many of the ideas over the past 3 months as we have implemented this. We are using a Slingbox to stream the video.
From the suggestions of others on this forum, we want to have an audio backup ready over a regular phone line -- just in case the video streaming runs into problems. I know how to receive phone audio using the crab-box to bridge between the phone line and sound system. I don’t know a simple way to send the audio over a phone line other than the obvious – using a muted speaker phone. Does anyone have a simple approach for an “off the shelf” or easy to build way to take a line level or mic level signal and “insert” that signal into a phone?
Regarding Telephone Audio back-up:
At our stake, we use a meeting house "pocket hearing impaired" receiver (with a fresh battery!) to provide a wireless audio feed to the "crab box" in the stake clerks office. The wireless audio service is already connected to the meeting house PA system, and the pocket units are always available on request for a hearing impaired member. These are existing church-provided materials.
The crab box connects easilly to the phone line in the clerks office with an RJ phone cord.
We use a single RCA female-to-female connector to join two of the crabs existing patch cords to form an adapter cable between the hearing aid jack and the crab's audio-in jack.
It works great and only takes a minute to set up.
At the remote ward, the audio link is provided by using a spread-spectrum wireless phone desk set in a clerks office. The roaming handset has an earphone jack which we can use for the house PA system if the computer or slingbox should fail. All we needed was a patch cord between telephone handset's mini-jack, and the ward's crab box to get into the house PA system.
We also have a jpeg folder of nice Temple Scenes ready to display from the laptop computer, if the slingbox path fails.
We actually used the phone backup for about 2 1/2 minutes last year when we experienced a brief sllingbox internet disconnect. Members could still participate in the sustainings, even though the video was briefly lost.
And they did !
