There’s a small change in Asterisk 1.6.0-beta7’s dsp.c. In order to compile chan_mobile you will have to do this.
enter your asterisk-addons directory
# cd asterisk-addons-1.6.0-beta2
enter the channels directory
# cd channels
edit the chan_mobile.c
# nano chan_mobile.c
Go to line 2000 and 2001
they look like this
ast_dsp_set_features(pvt->dsp, DSP_FEATURE_DTMF_DETECT);
ast_dsp_digitmode(pvt->dsp, DSP_DIGITMODE_DTMF | DSP_DIGITMODE_RELAXDTMF);
change them to look like this
ast_dsp_set_features(pvt->dsp, DSP_FEATURE_DIGIT_DETECT);
ast_dsp_set_digitmode(pvt->dsp, DSP_DIGITMODE_DTMF | DSP_DIGITMODE_RELAXDTMF);
now chan mobile will compile and run properly when you start asterisk.
enjoy!
