[asterisk-users] Multiple B410P's in one machine

[asterisk-users at rogg.is]

In an effort to better understand the interaction between multiple B410P's,
mISDN, chan_misdn and Asterisk, I hope someone can add a bit more details to
the clear and welcome answers presented so far.

Good to hear. Assuming I have the first card with four TE configured ports
and four BRI's coming in and the second card with four NT configured ports
and four BRI's going out to a PBX, am I right then in configuring this in
/etc/misdn-init.conf like so (leaving out what I think is not really
relevant to the discussion):

################################################
...
card=1,0x4,rxclock
card=2,0x4,pcm_slave
...
option=1,master_clock
...
poll=128
dsp_options=0
...
################################################

And in /etc/asteerisk/misdn.conf like so:

################################################
[general]
...
echocancel=yes
echotraining=no
echocancelwhenbridged=no
bridging=no
...
################################################

Incidently, if I set bridging=yes there is no sound heard between a call
coming in on a TE configured port (no difference between PTP or PMP config)
and going out again on an NT configured port. But that works (although with
stutter in the sound every 1.5 seconds or so) if bridging=no.

1) Is this to be expected? Should Hardware bridging not be a better choice?
2) With hardware bridging, can MixMonitor still record the conversation?
3) Is there any reason one would not just use software bridging?

tnx.
