I've been battling while creating an IVR using FreeSWITCH mod_managed and connecting through a CISCO 2811. Most things now work quite well, but I am having a few issues with the way the system answers calls (or doesn't answer calls...). I have FreeSWITCH running as a windows service on Windows Server 2008, which is connected via LAN to a CISCO 2811 with a 4 port FXO card, which is then connected to a POTS phone line. Take the following scenario: 1. Managed .NET application creates a call string and uses ESL to talk to freeswitch and originate a call: string callstring = "{bridge_answer_timeout=20,ignore_early_media=true,call_timeout=20}sofia/internal/1091234567@192.168.x.x '&managed(ivrAppName)'"; eslConnection.API("originate", callstring); where 192.168.x.x is the CISCO IP. 2. The CISCO sees that the phone number (1091234567) starts with a 1 so it uses FXO port 1 and strips the 1 and uses the remaining phone number (091234567) to make the call. 3. My phone rings, I pick up and I can hear my IVR playing. These are my current problems: - IVR starts playing before I even pick up the phone. This means that if the system calls a mobile phone and the person doesn't pick up, the IVR will start playing and eventually the mobile phone will divert to voice mail. Obviously I then get a missed call and an sms saying I have a new voice mail, which is annoying. Instead I would like it to KNOW that no one has picked up, but I don't know how to do this. Somehow the CISCO needs to be able to tell FreeSWITCH that the call has not yet been answered. For some reason however as soon as the CISCO starts calling FreeSWITCH thinks the call is already connected. It doesn't know that the CISCO is actually still ringing. Maybe I'm doing originate the wrong way or something ... - The phone only rings for about 10 seconds before hanging up. I've tried "call_timeout", "bridge_answer_timeout". I've also tried setting CISCO "ring number". Nothing works, my phone still only rings for about 10 seconds. I don't know if this is a FreeSWITCH issue or a CISCO issue. I'm leaning towards CISCO, because FreeSWITCH IVR just starts playing even if no one answers the phone.
