short answer: no disclaimer: somebody with better * experience, please review long answer: there are two drivers for analog modems, chan_modem_aopen and chan_modem_bestdata, which correspond to zyxel style voice commands (AT+VRX &c.) and usr/zoltrix style (AT#VRX &c.). off the top of my head, i can't remember which one is which but you can check it easily in the sources. with the two command sets mostly equivalent, the usr driver is incomplete (i hacked it into supporting rates other than 8khz as my zoltrix supports only 7200/11025 but it only rx'd audio. after a stream of mysterious segfaults i gave up trying to hack it into tx'ing audio too ;). i didn't have the chance to try the zyxel driver so i can't comment. there's some code for audio tx in the zyxel driver, but as i said, my attempts to copy the code to the usr driver failed miserably. also i tried a conexant winmodem (yup, still using dialup at home :(). under win98 at+fclass=? gives me 0,1,8 or the like (0=data, 1=fax class 1, 8=voice) but under linux i only have 0. eh, winmodems ;) *however*, i remember a discussion here about one of the * gurus planning to work on the modem drivers - will the brave individual please stand up? :) i'll happily help as i'd be interested in the driver too - haven't checked the development in the area for quite a time though. if anybody is interested in my patches for supporting audio rates other than 8khz (simplistic but acceptable quality sound resample routines right in the driver - good or bad?), let me know, i'll dig them up. > > Thanks in advance, > Bryan. > > Bryan Nolen > Lead Developer > http://Arc.Net.AU > http://cdonline.com.au hth, grzegorz nosek _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
