I am trying to create an IVR system that uses both POTS and IP phones and I have a few problems that I encountered with the IP SIP phones (Grandstream Budge Tone 102).
1. When a user hits the hook fast enough, the user can create multiple IVR connections that gives the appearance of an echo that is phased a few seconds apart. The way to reproduce this is by hitting the hook fast and furious. The telltale sign of multiple connections is when you get an echo from the IVR and or static caused by the multiple prompting. What could be causing this and how do I solve this. Here is the SIP config. 2. Poor audio quality over VPN broadband and direct Full T1. The audio recordings (in uncompress WAV format) that comes out at the IVR end is either muddled, static, or contains gaps. This occurs on both broadband and T1. What can be done to improve the audio recordings so they are audible. 3. How do I set up QOS on a broadband VPN when I do not control the bandwidth of the Internet? _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
