asterisk users - Mar 2009 - Digium B410P: misdn v1 or misdn v2 or dahdi + asterisk 1.6 ?

Hi,

Until now I've been using my Digium B410P cards with misdn 1.0.x.

I would like to upgrade my systems and am now wondering which is the
"best" route to take:

- use the latest release of misdn v1
- upgrade to the latest "stable" kernel and use the built-in misdn v2
- use misdn v2 as a seperate package (disable misdn in the kernel)
- use dahdi's support for misdn with asterisk 1.6 (not sure if this is true)

At a first glance I think I may be better off with the latest misdn v1 but would
like to know what other B410P users think about it.

Thanks,

Vieri

There is no support for mISDN v2 in Asterisk to my knowledge.

See above.

DAHDI does not have anything to do with mISDN. In Asterisk 1.6. the
B410P card can be used with either chan_misdn and mISDN v1 or with the
DAHDI wcb4xxp driver and chan_dahdi (using libpri for signaling) without
mISDN being involved at all. The only major caveat with
chan_dahdi/libpri is that NT-PtMP mode is not supported, but both TE
modes are supported and NT-PTP mode is as well.

It is available in a separate, out of tree module that is developed
alongside mISDNv2 (chan_lcr).

IIRC, though, hfcmulti is not yet supported by mISDNv2 .

If it aint broke, don't fix it...

Saying that, I can feel a need even now to look at 1.4 - I have many 1.2 
systems out there using mISDN but there are 1 or 2 who seem to suffer the 
"stuck channel" thing - only with Snom phones though, never
Grandstream...
And I'm told 1.4 has cured all this, however ...

Good luck with what you choose ...
