There are two Asterisk implementations: a channel interface and a dialplan application interface. Please ignore the noise, I need to slow down when I read. That is out of my hands at the moment unless it just can’t be done. Is that simply a side effect of having so many callers listening to the IVR at the same time? Members are those channels that are active in answering the Queue. However, the current desire is to work with already existing hardware. This is a simplistic calculation as there are going to be some references that have nothing to do with a call. 0 modules loaded, # grep enable= /etc/asterisk/cdr.conf enable=no. ; silence - Is the number of seconds of silence to allow before returning.

I will try to give a bit more detail on that now. I I’ve recently setup a small load test against an instance of Asterisks. I do agree with having multiple smaller servers. The sample file includes many examples of dialplan programming for specific scenarios and environments often common to Asterisk implementations. I have also tested with a separate set of audio files closer to what the actual IVR menu. The Asterisk command line interface (CLI) is reached by using the Linux shell command asterisk -r or rasterisk. I will explore Freeswitch a bit soon to compare it as well.

To transmit a fax from Asterisk, you must have a TIFF file. * With 500 calls/sec and the calls lasting 8 seconds that comes to 4000 Actually, the handling is so limited that if, for some reason, a FastAGI script fails during execution, Asterisk will simply disconnect the call. menuselect => Compiler Flags => Better Backtraces. I am struggling to find what the bottle neck is in this scenario. Download Free PDF. On my systems I have MoH and sounds installed in wav, ulaw, alaw, gsm and g729.
