Summary:                    One-way audio (one-way perfect and one-way
distorted) with SK65
Description: 
When making call from sipphone to cellphone through chan_mobile connected
to the Siemens SK65 i got a sco_out_buf overrun. 

I was try to fix this problem by ajusting sco_out_buf size, as described
in original track http://bugs.digium.com/view.php?id=8919 from 352 to 480,
492, 496 without any success.

With modified buffer management (and dtmf detection switched off)
chan_mobile/chan_cellphone runs with an average 10% cpu load on a 200 MHz
broadcom mipsel cpu (Asus WL500gd). 

Maybe this buffer management solves your distorted audio issue as well. So
you might want to have a look at
http://spblinux.de/fbox/openwrt/chan_cellphone/012-chan_cellphone.c.diff.
(The directory http://spblinux.de/fbox/openwrt/chan_cellphone/ contains
patches against the openwrt-kamikaze_7.06 build of asterisk 1.4 of Hans
Zandbelt: http://zandbelt.dyndns.org/).
