Hi all

I’ve got an issue with asterisk 1.6.1.6 and misdn with DDI configuration (NT, P2P). I can neither dial out nor in with DDI ISDN.

The problem seems, that l2 won’t come up. That is, for outgoing calls. No clue why incoming calls won’t work either.

My configuration looks as follows:

MISDN Stacks:

MISDN config:

/etc/mISDN.conf:
<mISDNconf>
        <module poll="128" debug="0" timer="no">hfcmulti</module>
        <module debug="0" options="0">mISDN_dsp</module>
        <devnode user="root" group="root" mode="644">mISDN</devnode>
        <card type="BN2S0">
                <port mode="nt" link="ptp">1</port>
                <port mode="nt" link="ptp">2</port>
        </card>
</mISDNconf>

Asterisk config:

[trunk_m1]
trunkname = ISDN
context = DID_trunk_m1
ports = 1ptp,2ptp
hasmisdn = yes
msns = *

Help is greatly appreciated!

Changing to TE was a good idea. That solved the problem.
RTFM… i know.
