[asterisk-users] Constant ''CHANUNAVAIL' on PRI for Outgoing Only
Hi, I'm hoping that somebody could possibly assist me with this. I've tried everything and I believe that my settings and configurations are 100% - CentOS 5.1 - 2.6.18-53.1.14.el5 Asterisk 1.4.19 libpri-1.4.3 zaptel-1.4.9 Connected via a Digium TE122P to a E1 PRI Incoming on any one of the numbers assigned to the E1 work fine and arrive at the Asterisk demo. No outgoing calls work and the following error is given: -- Executing [0215512345 at outbound:1] Dial("SIP/4700-085de988", "Zap/g0/0215512345|300|Ttr") in new stack -- Requested transfer capability: 0x00 - SPEECH -- Called g0/0215512345 -- Channel 0/1, span 1 got hangup, cause 44 -- Forcing restart of channel 0/1 on span 1 since channel reported in use -- Hungup 'Zap/1-1' == Everyone is busy/congested at this time (1:0/0/1) == Auto fallthrough, channel 'SIP/4700-085de988' status is 'CHANUNAVAIL' -- B-channel 0/1 successfully restarted on span 1 Here are all my settings related to this including an attached output of a "pri intense debug span 1" as span-debug.txt I really hope that somebody is able to assist me as the Telco says nothing is wrong on their side (even though they are sending somebody out to come verify) Thanks in advance! -------------------------------------------------------------------------------------------------------------------------------------------- /etc/zaptel.conf # # Zaptel Configuration File # span=1,1,0,ccs,hdb3,crc4 loadzone = za defaultzone= za bchan=1-15,17-31 dchan=16 #channel=1-15,17-31 -------------------------------------------------------------------------------------------------------------------------------------------- /etc/asterisk/zapata.conf ; ; Zapata telephony interface ; ; Configuration file [trunkgroups] [channels] language=en context=from-pstn signalling=fxs_ks rxwink=200 usecallerid=no hidecallerid=no callwaiting=yes usecallingpres=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes cancallforward=yes callreturn=yes echocancel=yes echocancelwhenbridged=yes echotraining=800 rxgain=0.0 txgain=-1.0 group=0 callgroup=1 pickupgroup=1 immediate=no busydetect=yes busypattern=2500,500 busycount=2 callprogress=no hanguponpolarityswitch=no callerid=asreceived cidsignalling=v23 cidstart=ring ;faxdetect=both faxdetect=incoming ;faxdetect=outgoing ;faxdetect=no switchtype=euroisdn pridialplan=unknown prilocaldialplan=unknown priindication = outofband callerid=asreceived jitterbuffers=6 ; PRI card - 1st span switchtype = euroisdn signalling = pri_cpe group = 0 context = demo channel => 1-15,17-31 -------------------------------------------------------------------------------------------------------------------------------------------- [root at pri1 ~]# cat /proc/zaptel/1 Span 1: WCT1/0 "Wildcard TE122 Card 0" (MASTER) HDB3/CCS/CRC4 IRQ misses: 22 1 WCT1/0/1 Clear (In use) 2 WCT1/0/2 Clear (In use) 3 WCT1/0/3 Clear (In use) 4 WCT1/0/4 Clear (In use) 5 WCT1/0/5 Clear (In use) 6 WCT1/0/6 Clear (In use) 7 WCT1/0/7 Clear (In use) 8 WCT1/0/8 Clear (In use) 9 WCT1/0/9 Clear (In use) 10 WCT1/0/10 Clear (In use) 11 WCT1/0/11 Clear (In use) 12 WCT1/0/12 Clear (In use) 13 WCT1/0/13 Clear (In use) 14 WCT1/0/14 Clear (In use) 15 WCT1/0/15 Clear (In use) 16 WCT1/0/16 HDLCFCS (In use) 17 WCT1/0/17 Clear (In use) 18 WCT1/0/18 Clear (In use) 19 WCT1/0/19 Clear (In use) 20 WCT1/0/20 Clear (In use) 21 WCT1/0/21 Clear (In use) 22 WCT1/0/22 Clear (In use) 23 WCT1/0/23 Clear (In use) 24 WCT1/0/24 Clear (In use) 25 WCT1/0/25 Clear (In use) 26 WCT1/0/26 Clear (In use) 27 WCT1/0/27 Clear (In use) 28 WCT1/0/28 Clear (In use) 29 WCT1/0/29 Clear (In use) 30 WCT1/0/30 Clear (In use) 31 WCT1/0/31 Clear (In use) [root at pri1 ~]# -------------------------------------------------------------------------------------------------------------------------------------------- "pri intense debug span 1", - attached as a text file due to its length. -------------------------------------------------------------------------------------------------------------------------------------------- /var/log/asterisk/full - not found, only: [root at pri1 ~]# ls /var/log/asterisk/ cdr-csv cdr-custom event_log event_log.0 messages messages.0 queue_log queue_log.0 however the only usefull output of messages: [Apr 16 21:17:30] WARNING[9905] app_dial.c: Unable to create channel of type 'Zap' (cause 0 - Unknown) -------------------------------------------------------------------------------------------------------------------------------------------- extensions.conf : [general] static=yes writeprotect=no clearglobalvars=no [globals] CONSOLE=Console/dsp ; Console interface for demo ;CONSOLE=Zap/1 ;CONSOLE=Phone/phone0 IAXINFO=guest ; IAXtel username/password ;IAXINFO=myuser:mypass ;TRUNK=Zap/1 ; Trunk interface TRUNK=Zap/g0 ; Trunk interface INCOMING=IAX2 [default] include => demo [outbound] ;exten => _X.,1,dial(${TRUNK}/${EXTEN},300,Ttr) exten => _X.,1,dial(Zap/g0/${EXTEN},300,Ttr) -------------------------------------------------------------------------------------------------------------------------------------------- Please let me know if anything else is required.
