Been around asterisk for two-plus years, but need a little input from the list on this topic. Have a potential client that wants to replace their old key system with *, but they want to integrate a commercial message service (they pay a monthly fee to have special MOH messages generated) into their system. The messages are essentially delivered to this customer via older generation audio equipment that interfaces to their key system via a standard audio RCA jack. (We're reseaching other alternative deliver mechanisms such as mp3's, etc, from the supplier, but have to assume for now that we need to inject MOH audio into asterisk via this RCA jack.) Does anyone have a relatively high audio quanlity method of interfacing such an external audio device into asterisk in a reliable way via an RCA jack?
I have not done this but I could probably send you in the right direction. * MOH uses a he standard out of an audio program (ie mpg123) you should be able to add a custom mohtype in the musiconhold.conf file. All you need is to 'play' the audio from the line in on your MB and put it on STDOUT. Otherwise you can 'record' the message via line-in, edit it for length, and convert to MP3.> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com > [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of > Rich Adamson > Sent: Friday, February 17, 2006 8:42 AM > To: Asterisk-users-list > Subject: [Asterisk-Users] MOH from RCA jack? > > > Been around asterisk for two-plus years, but need a little > input from the list on this topic. > > Have a potential client that wants to replace their old key > system with *, but they want to integrate a commercial > message service (they pay a monthly fee to have special MOH > messages generated) into their system.

My * pc has an integrated soundcard, should be ok for this type of application, I'd get an RCA-to-line jack cable (radioshack should have those ;) I know * can play hold music from a streaming server, and I know some streaming servers can stream from a line in, so the combination of the two should do the trick I think.

Barix Instreamer takes RCA in and MP3 or ulaw stream out. Asterisk can use either for MOH.

Next, you will need a sound card in the machine. USB audio interfaces are cool too (and they usually have a high SN ratio). Then you need to setup a custom MOH class and use arecord: http://linuxcommand.org/man_pages/arecord1.html I haven't done this, but I was intrigued by your question and thought I'd look into it. Let us know how it turns out! -- Kristian Kielhofner

You could have their existing MOH source device connected to the input of a PC in their office (or yours) like mentioned in previous messages. When the new media arrives, make a single MP3 file, and then upload it to the Asterisk server. Sincerely, Trevor Hammonds
Maybe you could just present it as an additional monthly cost to convert the legacy media to modern formats if their service provider can't do it. I'm sure it would take a very minor amount of time and you could probably bill them some tiny cost of $15. You might want to consider building it into a monthly support cost that would cover their adds/moves/changes. One of the key benefits to running * is the ability to change your phone system to fit your business as your business grows and changes. Take for example, we added a dedicated sales rep. We currently have a feature where callers can hit a number to talk to sales. Well, I want him to have first grab at the call so it rings his phone for 10 seconds, if he isn't right there it then rings a pool of phones where smart people sit. If nobody answers it goes back to his voicemail. This isn't easy to do with legacy PBX's.

My orginal question was based on the fact the customer has a paid subscription from this company to provide a "service", the customer will likely not want to mess with that service (and/or copyrights), and may just force the issue with interfacing at the RCA jack level. E.g., don't rock the boat with "change" when the customer is already stressin with the unknowns of voip, etc. (This is a non-tech customer.) _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
