Hi , I am currently experiencing problems with DTMF detection. My sip-phone using INFO to transfer DTMF, and I see that the version downloaded from asterisk ftp ( 0.4.0) do not support the d= field. I do a clean cvs from a W2K machine and see that in new chan_sip.c , this field has been recognized. But compiling under Linux give me following error. The error come from generating the dependency files. All the Makefile(s) was leave untouched. I was not sure what's the problem. Can some one help to point me to right way? TIA best regards, Nguyen [root@linuxbox asterisk]# make for x in res channels pbx apps codecs formats agi cdr astman; do make -C $x depe nd || exit 1 ; done make[1]: Entering directory `/usr/src/asterisk/res' Makefile:39: .depend: No such file or directory ../mkdep -pipe -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declara tions -g -Iinclude -I../include -D_REENTRANT -D_GNU_SOURCE -O6 -march=i686 -D ZAPTEL_OPTIMIZATIONS -DASTERISK_VERSION=\"\" -DINSTALL_PREFIX=\"\" -DASTETCDIR=\ "/etc/asterisk\" -DASTLIBDIR=\"/usr/lib/asterisk\" -DASTVARLIBDIR=\"/var/lib/ast erisk\" -DASTVARRUNDIR=\"/var/run\" -DASTSPOOLDIR=\"/var/spool/asterisk\" -DASTL OGDIR=\"/var/log/asterisk\" -DASTCONFPATH=\"/etc/asterisk/asterisk.conf\" -DASTM ODDIR=\"/usr/lib/asterisk/modules\" -DASTAGIDIR=\"/var/lib/asterisk/agi-bin\" -DBUSYDETECT -DNEW_PRI_HANGUP -DZAPATA_MOH -DOPENSSL_NO_KRB5 -fPIC `ls * .c` : unrecognized option Usage: /bin/bash [GNU long option] [option] ... /bin/bash [GNU long option] [option] script-file ...
