Sorry for confusing the issue, I should have stripped out that line from the dialplan as well. Given just the busy() line:
exten => 1005,n,Busy(20) The busy tone should(?) be generated from the PRI channel driver. This is the tone that the Telco is saying is being sent incorrectly. I've looked at the dahdi configs, and it is setup correctly to use US tones. -Justin ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Eric Wieling Sent: Monday, August 04, 2014 8:33 AM To: Asterisk Developers Mailing List Subject: Re: [asterisk-dev] How to diagnose early media on a PRI Run Progress before the playtones. This is documented in https://wiki.asterisk.org/wiki/display/AST/Early+Media+and+the+Progress+Application --Eric --- Frequently Asked Questions Q1: How do a transfer a call using a Polycom phone? A1: While on a call press the Transfer button on the phone, wait for dialtone, dial the number you want to transfer to, wait for the person answer, tell them you are transferring a call, then press the Transfer button the phone a second time. Q2: I don't want to wait for the person answer when transferring a call. A2: Press the Transfer buton on the phone, the press the Blind softkey, the dial the extension you want to transfer the call to. The transfer should complete automatically. If it does not, you may need to press the Send softkey Q3: Where can I find more information on using Polycom phones? A3: Go to http://help.nyigc.net/ for documentation for Polycom phones. Q4: What is the best kept secret on the Internet? A4: That would be the InterGlobe Help Site, at http://help.nyigc.net/ Q5: When calling my VMAX fax line I always get a busy signal. A5: You must call VMAX fax lines either from another VMAX fax line or from a non-VMAX voice line. If you call a VMAX fax line from a VMAX voice line you will always receive a busy signal. From: [email protected] [mailto:[email protected]] On Behalf Of Justin Killen Sent: Monday, August 04, 2014 11:25 AM To: Asterisk Developers Mailing List Subject: [asterisk-dev] How to diagnose early media on a PRI I asked this on the users list a week and a half ago but haven't gotten any response. I'm hoping someone here with PRI/ISDN experience can help guide me in the right direction. I have a dialplan (freepbx) that plays a busy signal in-band when an extension is busy (before an Answer). Stripped down, it looks like this: exten => 1005,n,PlayTones(busy) exten => 1005,n,Busy(20) Note that there is no Answer() prior to this. Our trunk is a PRI. When I call into this extension from outside, I get about 25 seconds of ringing, followed by a hangup. Looking at the asterisk logs, 20 seconds of that delay is AFTER the PlayTones() function is invoked. I talked with our Telco about this, and they want to refer to in-band tones prior to answer as a media cut-through. The tech said that it is enabled on their end, and he did some test calls and got some ISDN trap logs. He is saying that the PBX is playing the ring-back tone instead of the busy tone, but I don't think that's the case (If I add an Answer() to the dialplan, I do in fact hear the busy tone). Is there anybody out there who has experience with reading/analyzing IDSN trap logs (Q931) that can help me narrow down where the issue is and how to fix it? Thanks, -Justin
