<div dir="ltr"><div><div>John,<br><br></div>I don't care about the bandwidth. My issue is with the cost of running madplay each instance of madplay. If we have 1000 possible streams and madplay using 0.3 of a core per CPU is 3 full cores just to pull the streams. What I am looking for a is a hybrid where we use the behavior of cachertclasses=no but if there are more than one people on hold we use the same "pull" so we aren't invoking madplay over and over.<br><br></div>Another option would be to create a revert ices to play a stream from an icecast server.

Only pull the stream if some one is invoking MOH for this moh class and if there is no one else on hold to kill it.

1) I want to be able to add a few hundred streams per box. Not all streams are being listed to at once. Once you add a MOH class to musiconhold.conf it stays up forever (which I can understand why). When trying realtime madplay wont be loaded until it's called in the dial plan. After that it is in Asterisk until I restart asterisk. If we have 20-30 streams it's OK but once that grows it can bog down the machine.<br>

2) I found that it for some reason the stream returns a 404 (it goes off line etc.) then 10-15% of one core gets locked up until the stream comes back online. The issue is that if a few streams have an issue then I am locking up one care.<br>

For these and other reasons, I think streaming is dumb (in most cases).<br>
<br>
I have a client that wanted to allow his customers to enter URLs for their moh. Bad idea. They kept entering invalid URLs which would cause bits to crash. Further, we started getting complaints from URL providers as to why we were streaming 24x7 and from our colo about the bandwidth.<br>
<br>
My solution* (which the customers either haven't figured out yet or don't mind) was:<br>
<br>
1) Customers submit URLs to my client.<br>
<br>
2) Once entered into the system, the customer can select the 'station' from a web page.<br>
<br>
3) I record 24 hours of the stream and then use sox to break into separate files on the silence between songs.<br>
<br>
4) I create a moh class that random plays the files.<br>
<br>
*) My client approved the solution which may be of questionable legality depending on the stream.<span><font color="#888888"><br>
