Hello, I have a problem with my installation. First I have to say that I am a begginner in Elastix and PBX systems. My problem is that I can make internal calls between the clients but I wasn't able to establish neither outbound calls nor incoming calls to my system. My network is like this: - ISDN Line from German Telekom - a Router (7170 FritzBox) - Elastix 2.0 installed on a Server PC with an ISDN Card with HFC-S for Asterisk Trixbox Elastix - 3 Client PCs with softphones on the same network I have done lots of changes in the Trunk Settings and Outbound & Inbound Routes with no success. These settings are now like that: Trunk Settings: Code: Custom Trunk Trunk Description: CustomTrunk Outbound Caller ID: "Twin Brain" <0211 758467-00> CID Options: Allow Any CID Maximum Channels: Dial Rules: 9|X. Custom Dial String: mISDN/g:ta/$OUTNUM$ Outbound Routes: Code: Route Name: MyOutbound Route CID: (empty) Dial Patterns: 9|X. Trunk Sequence: 0 mISDN/g:ta/$OUTNUM$ I have not configured any inbound routes yet. I have added a new context at the end of misdn.conf: Code: [ta] ports=1 context=from-pstn msns=* echocancel=no overlapdial=no senddtmf=yes far_alerting=yes te_choose_channel=no nationalprefix=90 internationalprefix=900 rxgain=0 txgain=0 The dahdi_scan output: Code: [root@localhost ~]# dahdi_scan  active=yes alarms=OK description=HFC-S PCI A ISDN card 0 [TE] name=ZTHFC1 manufacturer=Cologne Chips devicetype=HFC-S PCI-A ISDN location=PCI Bus 01 Slot 01 basechan=1 totchans=3 irq=82 type=digital-TE syncsrc=0 lbo=0 db (CSU)/0-133 feet (DSX-1) coding_opts=AMI framing_opts=CCS coding=AMI framing=CCS [root@localhost ~]# Under Hardware Detector I have this entry: Code: Misdn Card Port 1: TE-mode BRI S/T interface line (for phone lines) -> Protocol: DSS1 (Euro ISDN) -> Layer 4 protocol 0x04000001 is detected, but not allowed for TE lib. -> childcnt: 2 * Port NOT useable for PBX (maybe there is already a PBX running?) -------- Whit this configuration, I got it ONLY FOR ONE TIME work. I could have establish a call to my home number. I answered the call, all went allright. But then I gave a break, then I would like to add also Inbound Routes to be able to receive calls as well. And it didn't work for the first try. And I would like to test one more time to call my home number, it didn't work again. I'll go mad with that :/ What did I change, or what went wrong? I don't know. Any ideas?? Any help with be appreciated. Thanks in advance. With my best regards, Yordanov.
