With kernel 2.6 you only get ISDN tty devices through the capidrv module, no more analog modem login support with the obsoleted diva2i4l module. > The Junghanns BRI boards have no such on-board logic, they are pure telephone > interfaces driven by the host - and as such they are /perfect/ for Asterisk. You get benefits from the zaptel interface (zapscan, zapbarge, etc.), closer to the metal, less latency. > We use an Eicon Diva Server 4BRI for our fax server because of the TTY > interface for Hylafax - the DSPs themselves do all the fax negotiation / > compression and it works extremely well. It works, but when ISDN channels are busy faxing, asterisk has no way to know which outgoing channel is free: users get a congestion when trying to call out (unless you program some channel testing logic/loop inside your dialplan). This is a major bummer in production. > However, we're also running * on that machine via CAPI, and the board > gives us the flexibility to share 8 channels between * and Hylafax > really easily :) There is no sharing, they contend for the channels, even thought they both use the capi layer. Go figure. My experience with both cards is that the Diva is a waste of money. It's better to go with the Junghanns card and do faxing from inside asterisk, which works very well in the latest versions. -- They can have my jeans, as soon as they pry them off my dead, cold ass. -- (Spackler on /. about corporate dress code becoming formal again) _______________________________________________ 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
