Hi,
I am very interested in asterisk, and have been trying to work out a way I can get it going on my system. The modem I use is a Banksia WaveSP56, which to all indications has a generic rockwell chipset.
I'm running this on a stock redhat 6.1 system (linux 2.2.12) with a pentium 233 and 64mb RAM. The ATI3 response from the modem is:
V2.083-K56_2M_DLS
The first problem I hit was that my modem doesn't seem to support 8000hz? The only values that work are 11025 and 7200. I tried tweaking the commands sent to the modem, but I suspect this logically can't work unless asterisk has some sort of resampling as it probably uses 8000hz internally - the recording overran as a result? I couldn't seem to find any other reference to the magic number 8000 except in the chan_ixj.c file where it is used for some freq calculations and a buffer size.
I am keen to hack this up on my system, but I'm still rather elementary - is this the right direction to be thinking? and does anyone have any pointers about this sampling rate? or even know what is wrong with this picture?
