Ignore busy signal when dialling out on an FXO port
Hi, I'm new to freeswitch so please excuse me if I'm not using the right terms. I have freeswitch connected to a POTS line using an FXO port, and I am trying to use it to dial out without success. The POTS line requires me to dial '9' first to get a line for dialing out, and as long as I don't press 9 it gives a 'busy' tone. I am trying to bridge an extension to freetdm port with adding a '9' prefix, but I get "Failed to open channel" and the reason is "NORMAL_CIRCUIT_CONGESTION". When I look at 'ftdm dump' I see: "last_state: BUSY". I guess the reason for failure is that freeswitch hears the busy tone and thinks the line is not free and aborts. I also thought this is related to the early media signaling so I tried adding {ignore_early_media=true} thinking it will ignore the busy tone, but it dodn't help. How can I tell freeswitch to ignore the busy signal and just dial the destaination number, (the '9' prefix will give it a free line)? Thank you very much for the help, Oren Hecht.
Please post your dialplan snippet. Re POTS line requiring you to dial 9. Usually this is a PABX access code to grab the LINE e.g. to get a dial tone but 9 is not dialed. Only the numbers following 9 is actually dialed to the POTS line. Unless ... this is an unusual setup. /nandy On Mon, Nov 18, 2013 at 3:41 PM, Oren Hecht <orenhe@in.taldor.co.il> wrote:

"NORMAL_CIRCUIT_CONGESTION" has nothing to do with the busy tone. There should be problem with your TDM card(sangoma). You can firstly check if your link and cic state are normal before you dial the call. To check the state, you can either check the freeswitch.log or use "wanpipe" trace. windy 2013-11-19 From： Nandy Dagondon Send： 2013-11-19 07:59:23 To： FreeSWITCH Users Help CC： Subject： Re: [Freeswitch-users] Ignore busy signal when dialling out on anFXO port Please post your dialplan snippet.

I am using dahdi for my tdm card. I have 1 FXO and 1 FXS installed. At the moment I am trying to check if I can bridge the 2 ports, so freeswitch will just pass the call. 1. If I dial the phone number of the POTS line that is connected to the FXO port, then freeswitch bridges it to the phone that is connected to the FXS port, I answer the phone and it works well. The other way around doesn't work though. The simplest test that I am doing is that if I pickup the handset and dial any number, I want freeswitch to bridge the call to a specific phone number with the '9' prefix that is required. This doesn'twork as I get the errors that I stated in my previous mail. If I connect the phone directly to the POTS line and dial the same exact number (with the '9' prefix) it works. my dial plan is: <!-- THIS DOESN'T WORK --> <extension name="call_from_phone"> <condition field="${freetdm_span_number}" expression="^1$"> <action application="set" data="hangup_after_bridge=true"/> <action application="bridge" data="freetdm/2/1/9039000000"/> </condition> </extension> <!-- THIS WORKS --> <extension name="call_from_pots"> <condition field="${freetdm_span_number}" expression="^2$"> <action application="set" data="hangup_after_bridge=true"/> <action application="bridge" data="freetdm/1/1/"/> </condition> </extension> The error I get: 2013-11-19 14:07:26.727378 [INFO] ftmod_zt.c:671 Setting echo cancel to 64 taps for 1:1 2013-11-19 14:07:30.987378 [NOTICE] switch_channel.c:1034 New Channel FreeTDM/1:1/2 [2a930dc8-5113-11e3-82d6-7bb8ac46d104] 2013-11-19 14:07:30.987378 [INFO] mod_dialplan_xml.c:558 Processing <1>->2 in context analog 2013-11-19 14:07:30.987378 [INFO] ftmod_zt.c:671 Setting echo cancel to 64 taps for 2:1 2013-11-19 14:07:30.987378 [NOTICE] switch_channel.c:1034 New Channel FreeTDM/2:1/9039000000 [2a934748-5113-11e3-82dc-7bb8ac46d104] 2013-11-19 14:07:30.987378 [INFO] ftmod_zt.c:671 Setting echo cancel to 64 taps for 2:1 2013-11-19 14:07:36.047378 [NOTICE] mod_freetdm.c:2273 Hangup FreeTDM/2:1/9039000000 [CS_CONSUME_MEDIA] [NORMAL_CIRCUIT_CONGESTION] 2013-11-19 14:07:36.047378 [NOTICE] switch_core_session.c:1564 Session 14 (FreeTDM/2:1/9039000000) Ended 2013-11-19 14:07:36.047378 [NOTICE] switch_core_session.c:1568 Close Channel FreeTDM/2:1/9039000000 [CS_DESTROY] 2013-11-19 14:07:36.047378 [INFO] mod_dptools.c:3201 Originate Failed.
