We've done this several times with Junghanns Cards - nearly no problem,
just the normal dialplan entries.

[data-isdn]
exten => 246,1,Wait
exten => 246,2,zapEC(off)
exten => 246,3,Dial(Zap/48/5552,20)
exten => 246,4,Macro(hangupcall)

For outbound calls just use your normal dialout-settings.

The only mentionable thing is, that we had to take away all settings for
txgain and rxgain in zapata.conf for the affected channels. If we had
something like rxgain=1.0 in zapata.conf for the PRI-card the
ISDN-Connection was established through asterisk (briging of e.g. Zap/1-15
and Zap/48) but the LCP-Negotiaton of the PPP failed. Perhaps someone has
a clue on this. Tested version was Asterisk 1.0.5 with bristuff patches.
This affected inbound an outbound calls
