There are over 100 open items on the Digium board related to DAHDI. I'm sure quite a few are "chair-to-keyboard" issues, but here are two real ones: 1. DAHDI will not look for a connection when dialing, so if I make a call and play a file, X percent of the file plays before the person actually (if ever) answers the phone. 2. DAHDI (IMO and IME) is more difficult to tune than Zaptel.
I'm certain that DAHDI will be solid and great in a few years; It just doesn't seem to be yet. Zaptel isn't the "end all" either; I upgraded to 1.4.25-rc1 because I couldn't get zaptel to tune sufficiently on 1.4.21.2. We use POTS for our outgoing service and haven't gotten satisfactory results with DAHDI or Zaptel on TDM400 and TDM410. I've spent probably 4 1/2 of my 8 months exposure to Asterisk just trying to get the sound right on calls. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jared Smith Sent: Thursday, May 28, 2009 1:18 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Best Current Release for Long Term Use On Thu, 2009-05-28 at 12:58 -0500, Danny Nicholas wrote: > This being said, I'd probably go with 1.4.21.X since anything above > that replaces zaptel with DAHDI. There are still a lot of things "To > be worked out" in DAHDI - Zaptel is a pretty solid standard. It continues to amaze me when I hear this, as there really isn't much difference between Zaptel and DAHDI. In fact, the only two differences I know about are: 1) The name change 2) Making software echo can modules able to be loaded on a per-channel basis 3) DAHDI will continue to be developed, Zaptel will not I've been using DAHDI in both my personal systems and in the Asterisk training classes I teach for more than six months now, and I have yet to find any reason not to use it. If you're having problems with DAHDI, mind sharing the specifics of what those are? I've also been using the 1.6.0 branch of Asterisk, and it's been *much* more solid than the 1.4 branch for me and the things I use. It's not to say there haven't been some quirky little bugs, but overall I've been very happy with it. As far as Linux distributions go, I'd say go with whatever you're most comfortable with, and will have the best chance of supporting over the long term. I personally like RHEL and CentOS, but Debian or Ubuntu LTS would be great choices as well, as they all have *years* worth of updates rather than months.
