Hi! I’m having problem with Asterisk and ISDN. I installed mISDN 1.2 (from cvs) and it installed OK. When I do mISDN scan, I get following: [color=blue]\> mISDN scan 1 mISDN compatible device(s) found: > > hfcpci[/color] My mISDN.conf (/etc/mISDN.conf) is following: [color=blue] hfcmulti mISDN\_dsp mISDN 1 [/color] I have also created misdn-init.conf (just in case - also in /etc) and it reads: [color=blue]# # Configuration file for your misdn hardware # card=1,hfcpci te\_ptmp=1 poll=128 dsp\_poll=128 dsp\_options=0 dtmfthreshold=100 debug=5 timer=0[/color] When I start mISDN I get following: [color=blue]\> mISDN start – Loading mISDN modules – > > /sbin/modprobe --ignore-install capi > > /sbin/modprobe --ignore-install mISDN\_core debug=0 > > /sbin/modprobe --ignore-install mISDN\_l1 debug=0 > > /sbin/modprobe --ignore-install mISDN\_l2 debug=0 > > /sbin/modprobe --ignore-install l3udss1 debug=0 > > /sbin/modprobe --ignore-install mISDN\_capi > > /sbin/modprobe --ignore-install hfcpci protocol=0x2 layermask=0xf > > /sbin/modprobe --ignore-install mISDN\_dsp debug=0 options=0[/color] Also, mISDN.conf (in /etc/asterisk/) is following: [color=blue][general] misdn\_init=/etc/misdn-init.conf debug=2 bridging=yes stop\_tone\_after\_first\_digit=yes append\_digits2exten=yes dynamic\_crypt=no [default] context=isdn-default language=en senddtmf=yes rxgain=0 txgain=0 te\_choose\_channel=1 dialplan=0 localdialplan=0 ;cpndialplan=0 msns=\*[/color] I start (for testing) asterisk with following: asterisk -vvvvvd And in log I get this (in regard to mISDN): [color=blue][Aug 19 23:51:07] VERBOSE[4350] logger.c: chan\_agent =\> (Agent Proxy Channel) mISDN\_close: fid(18) isize(131072) inbuf(0x2aaaab030010) irp(0x2aaaab030010) iend(0x2aaaab030010) [Aug 19 23:51:07] VERBOSE[4350] logger.c: == Parsing ‘/etc/asterisk/misdn.conf’: [Aug 19 23:51:07] DEBUG[4350] config.c: Parsing /etc/asterisk/misdn.conf P[0] No te ports initialized [Aug 19 23:51:07] VERBOSE[4350] logger.c: Found [Aug 19 23:51:07] DEBUG[4350] channel.c: Registered handler for ‘mISDN’ (Channel driver for mISDN Support (Bri/Pri)) [Aug 19 23:51:07] VERBOSE[4350] logger.c: == Registered channel type ‘mISDN’ (Channel driver for mISDN Support (Bri/Pri)) [Aug 19 23:51:07] VERBOSE[4350] logger.c: == Registered application ‘misdn\_set\_opt’ [Aug 19 23:51:07] VERBOSE[4350] logger.c: == Registered application ‘misdn\_facility’ [Aug 19 23:51:07] VERBOSE[4350] logger.c: == Registered application ‘misdn\_check\_l2l1’ P[0] – mISDN Channel Driver Registered – [Aug 19 23:51:07] VERBOSE[4350] logger.c: chan\_misdn =\> (Channel driver for mISDN Support (BRI/PRI)) [Aug 19 23:51:07] VERBOSE[4350] logger.c: == Parsing ‘/etc/asterisk/cdr\_manager.conf’: [Aug 19 23:51:07] DEBUG[4350] config.c: Parsing /etc/asterisk/cdr\_manager.conf[/color] Any idea why I always get following: [color=blue]\*CLI\> mISDN show channels Chan List: (nil)[/color] or what is wrong - I can’t get any incoming call, it even doesn’t register in debug that there is a call incoming… Please, please help… Reagrds, Aj ---

You missed the “ports” definition, check how I defined my hfc card in /etc/asterisk/misdn.conf: [hfc] ports=1 msns=\* context=hfc\_test Hope it helps. Marco Bruni. ---

Strangly, this is SOLVED. If anybody gets this error: [color=blue]P[0] handle\_bchan: BC not found for prim:120282 with addr:52010101 dinfo:ffffffff [/color] or KERNEL error [color=blue]mISDN\_rdata: rport queue overflow[/color] The solution is rather simple - RTFM for mISDN. In /etc/asterisk/misdn.conf you should add following: [color=blue]jitterbuffer=4000 jitterbuffer\_upper\_threshold=0[/color] And Asterisk is now up and running… Regards, Aj ---

LNX, changed dr to: [color=blue]cd /usr/src[/color] Then I used cvs to get newest mISDN - version 1.1.5 didn’t compile.: [color=blue]cvs [-d:pserver:anonymous:readonly@cvs.isdn4linux.de](mailto:-d:pserver:anonymous:readonly@cvs.isdn4linux.de):/i4ldev co mISDN mISDNuser[/color] After that I “[color=blue]cd mISDN[/color]” And then I had to type this 1. (can’t remember if it is possible or not, but you can try) [color=blue]./configure[/color] 2. [color=blue]make[/color] 3. [color=blue]make install[/color] then cd /usr/src/mISDNuser and again: 4. [color=blue]./configure (if it can run, if not ignore)[/color]2) [color=blue]make[/color] 5. [color=blue]make install[/color] When it finished installing new mISDN, I typed following: [color=blue]mISDN scan mISDN config mISDN start[/color] It is reccomended to reboot (just tu be sure that it loads it automaticly)). This was part I of my “fun time” with ISDN BRI card. Regards, Aj And you have to repeat this
