Re: Incoming call issue between PABX and R3600 using ISDN QSig.

Use "direct-inward-dial" under

pot dial-peer.

Since this is Qsig the digit may not be sent in block but in two seperate messages. For the router interface to understand this and wait for all digit before attempting a match you might want to inlude the following command under the D channel interafce se0:23 or 0:15

isdn overlap-receiving

isdn send-alerting

isdn sending-complete

The most important is "Overlap receiving" the rest are optional.
