Hi Cosmin I saw in the archives that you achieved getting msn & did working. Perhaps you can help me a bit on it. Currently i have a running 1.2.19 with latest misdn. I can generate sip => isdn call, which uses the default number connected to the line. No incoming calls are detected (yet) On my isdn-line i have multiple MSN's What i want is: 1) when user "X" places an pstn call, he sends msn "A" on the line when user "Y" places an pstn call, he sends msn "B" on the line 2) when receiving an isdn call if DiD "P" is called, use dialplan "K" if DiD "Q" is called, use dialplan "L" 3) Filtering on - specific CLID - anonymous calls (no clid) All help is welcome Hans
