Perhaps someone with more experience can help me solve this puzzle: Asterisk 1.4.18 on a Dell PowerEdge SC440, CentOS 5, 2.6.18-53.1.14.el5, Digium TDM400 with 3FXO(1-3) and 1FXS(4)
Phone service is provided by XO Communications via their XOptionsFlex service (5 analog lines, 3 of which are used by Asterisk). For simplicity I refer to them as xx43, xx44, and xx45 - based on their phone numbers. They are connected to the Digium as follows: xx43 = FXO 1 xx44 = FXO 2 xx45 = FXO 3 Here is the problem: When I connect the Asterisk box to the analog lines the first two lines (xx43 and xx44) will instantly switch to "busy". xx45 works fine - incoming and outgoing calls work as expected. I had XO check the lines - all three lines are programmed the same in their equipment. The work OK - until they are connected to the PBX - when xx43 and xx44 instantly switch to "busy". I checked the lines with an analog phone: Each line wokred fine when I plug an analog phone into it. I suspected that my FXO ports 1 and 2 may be bad. Thus I connected FXO 3 - which is working with xx45 - to line xx43 and then xx44: They went "busy" right away in either case. I connected FXO 1 and then 2 to line xx45: Worked fine both times. I replaced the entire TDM400 with another card, and repeated the above tests - the results were the same as above. >From those experiments I think I can rule out that the card is defective, as every FXO channel works with line xx45. None of them work with lines xx43 and xx44. I finally replaced the Digium card with a Sangoma A200 with 4 FXO ports (using 1-3 while leaving 4 unused). All 3 lines work as they should. Does anyone have an explanation for this strange behavior? Any suggestions on how to fix it? I would like to get the Digium card to work with this setup as I need the 4th (FXS) port for an analog extension in the office. /etc/zaptel.conf: fxsks=1-3 fxoks=4 loadzone = us defaultzone=us /etc/asterisk/zapata.conf: [channels] musiconhold=default usecallerid=yes hidecallerid=no callwaiting=no threewaycalling=yes transfer=yes echocancel=yes echotraining=yes signalling=fxs_ks context=incoming group=1 immediate=no channel=>1-3 ; Internal phone: signalling=fxo_ks context=internal group=2 channel=>4 Thanks for your assistance!
