[Asterisk-Users] TE205P E1 PRI card and other problems
I some have problems with TE205P E1 PRI card. The Asterisk installation is as follows: Zaptel-1.2 drivers with Asterisk CVS HEAD from November First 1 TE205P E1 card with span 1 connected to the PSTN and span 2 connected to the digital E1 interface card of a Panasonic super hybrid PBX. 1 Voicetronix VPB4 card connected to the analog interface of the PBX (For dialing internal PBX extensions and mobile phones) Agents using SIP softphones use the TE205P to make outgoing calls on span 1 connected to the PSTN. Incoming calls on span 1 are bridged to span 2 and the call is passed to the PBX. TE205P seems to drop the calls from the PSTN side. This happens quite often and is causing great losses for the business. The calls being dropped are either incoming or outgoing. The reason I couldn't use Asterisk-1.2 with zaptel-1.2 drivers is that I am using the mysql realtime extensions on the system and Asterisk-1.2 seems to have problems with mysql realtime so I had to fall back on the CVS HEAD of November which works greatly with mysql and also with the TE110P card. Here is my /etc/zaptel.conf file: span=1,1,0,ccs,hdb3,crc4 span=2,0,0,ccs,hdb3,crc4 bchan=1-15 dchan=16 bchan=17-31 bchan=32-46 dchan=47 bchan=48-62 loadzone = fr defaultzone=fr And here is my /etc/asterisk/zapata.conf ; ; Zapata telephony interface ; ; Configuration file [trunkgroups] ; Spanmap: Associates a span with a trunk group ; spanmap => <zapspan>,<trunkgroup>[,<logicalspan>] ;spanmap => 1,1,1 ;spanmap => 2,1,2 ;spanmap => 3,1,3 ;spanmap => 4,1,4 [channels] context=default switchtype=euroisdn pridialplan=unknown ; Overlap dialing mode (sending overlap digits) ;overlapdial=yes ; signalling=pri_net usecallerid=yes hidecallerid=no callwaiting=yes ;usecallingpres=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes ;canpark=yes ;cancallforward=yes ;callreturn=yes echocancel=yes echocancelwhenbridged=no rxgain=0.0 txgain=0.0 ; ; Logical groups can be assigned to allow outgoing rollover.

If so how can I put each card on a separate IRQ (No free IRQs on the system). I also have horrible echo problems on the Voicetronix card, I have tried everything to solve the problem with no success. The only thing that seems to lessen the ECHO is to reduce the rx gain for both hardware and software, but I still get an audible echo on the line.
