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/).
