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.
What sort of VPN? There are potential issues under certain
circumstances with latency involved in the connection. These can be
fixed however.
I larger issue is likely to be QOS in general.
3. How do I set up QOS on a broadband VPN when I do not control the
bandwidth of the Internet?
You can definitely have issues with general internet traffic if you set
up VPN on your router. However, these are far less serious than if you
don't. You want to set up QOS on whatever network interface is closest
to the internet and can control all of the traffic between your network
and the internet.
