Hi! I want to get audio from the PSTN before the call is answered so I don't miss when the called phone is busy or if there is some error (like the phone is unavailable or is wrong, etc) and hear the ringing from my telco. I have polarity reversal in my telco for incoming and outgoing calls. If I set answeronpolarityswitch=yes then I get no audio until the call is answered. If I set it to

hi: In my zapata.conf i have 4 fxo configured channels,for fxo number 1 to 3 i added polarity reversal property but for fxo number 4 i didnt add polarity reversal property but it still giving me on cosole that fxo number 4 is polarized (because the line on fxo number 4 is not polarized). what i want to do is to not let polarity reversal take effect on fxo number 4. that what i have in my

Today I received a TDM11B (1 FXO and 1 FXS) and got it installed just fine. I bought the card mainly to get caller ID to work properly in Sweden, and that works just fine. However, if the called or calling party hangs up after I hangup my SIP channel, polarity CID detection kicks in and dials a couple of signals to my incoming context. This happens with Asterisk 1.0.6 and CVS-HEAD. I have tried

Hey guys, I've been struggling with hangup detection on a Centrex system for a bit now, I was on site Saturday and I took my DMM with me. It would appear that this Centrex service provider uses polarity reversal at the beginning of a call and several times after hangup. I've been reading the archives for the last year and it looks like there was some work done that matches my

Can anyone tell me what this message means? Got event 17 (Polarity Reversal)... I'm running DAHDI 2.0 with a TDM401 card. Asterisk version 1.6.0. It appears that I get this Polarity Reversal each time an inbound call hangs up. This results in another ring, but no one is there. It appears as an unknown caller, but I believe its a phantom.

Hi ! I have some issues, i don't know exactly if it's a busy detection issue. When i dial into the Asterisk box, and if i hang up before the Asterisk answers with the IVR Welcome message, the Asterisk goes on with the call. But, if i wait for the Asterisk to answer, and if i hang up, the Asterisk hangs up too. I have this parameters on zapata.conf: busydetect=no

Hello, I have : answeronpolarityswitch=yes on chan_dahdi.conf but it's making all my lines answer on polarity reversal, this causes a problem for PSTN lines, so how can I set these lines to answer immediately (when it rings)? thanks -------------- next part -------------- An HTML attachment was scrubbed...

I've just had polarity reversal provisioned by our telco to test hangup detect with a TDM400P I've set hanguponpolarityswitch=yes in zapata.conf When I start Asterisk I get "ignoring hanguponpolarityswitch" in /var/log/asterisk/messages I assume that the option is either not valid or conflicts with another setting somewhere. Any ideas?

Hi, I'm having trouble with dialing out on analog lines. Asterisk can't seem to detect "answers". I have two zap groups. Group 1 is connected to an external analog PSTN provider. This group seems to work fine, especially with "answeronpolarityswitch". Group 2 is a group of "GSM gateways", ie. devices that host SIM cards so that you can dial from any PBX
