i4l: Trouble with outgoing DTMF (not working), less ISDN features than chan_capi, known to be not very stable/reliable (?works only with HiSax cards?), reportedly messy code, issues with echo and latency chan_capi: more features (early dial, call deflection, ISDN hold & retrieve etc), stable, comes with echosquelch, works only with cards that have CAPI driver support; far more popular among Asterisk users compared to isdn4linux; can't detect if another application outside Asterisk is already using a specific ISDN channel (?) zaphfc: works only with HFC cards, can also be used in NT mode (so that you can connect an ISDN PBX or an ISDN phone to Asterisk), works as ZAP channel and thus comes along with all the usual ZAP features (echo cancellation, ZAP timer, but also ZapBarge etc) chan_misdn: very new; needs misdn kernel module or kernel 2.6.x; not widely used (yet) Cheers, Philipp _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
