Here you have to differentiate between ISDN PRI and ISDN BRI lines. The mISDN module supports ISDN BRI while libpri/zaptel is supporting ISDN PRI. Small companies have a bunch of BRI lines (2 voice-channels per BRI). Medium size / bigger companies are using PRIs. You have up to 30/31 channels per PRI. Now, mISDN is patched against oslec. If you run mISDN from trunk, you get automatically oslec. No need to select the oslec package separately. I don't know if the oslec package which is available for Zaptel is also enhancing PRI calls. No idea, I have no test environment for this. Furthermore, there is a 'competitor' of mISDN which is called bristuff. Bristuff is set of patches against zaptel. The pro is, you don't need chan_misdn in Asterisk, but only zaptel. The con is, that it's a messy patchset. What's better? What provides the better quality? Well, check out the millions of discussions and battles on the internet about this subject. There is no clear winner! I integrated mISDN because it is totally independent from what can happen to Asterisk/Zaptel. If you upgrade/downgrade zaptel, your ISDN (BRI!) configuration is not touched. If you use bristuff, you must have the proper patches (plus some supplemental patches) for Zaptel. Easy up-/downgrading of Zaptel is not guaranteed and often not possible. To end this, if someone is keen on getting bristuff ISDN into Astlinux, it is doable, but I have no resources available myself to maintain this patchset. Let me know if someone has further questions on this subject. cheers, Ingmar ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
