sound card and microphone is not setup properly or you are running
other applications. Free softphones may not have the necessary codec
for good call quality.
When you run
a pingplot test, ensure that your latency times to our server is
less than 150ms or 150 milliseconds (time it takes for data to
travel from your device to our server).
VoIP ports are open. Please ensure that your firewall or your
ISP (internet service provider) is not blocking those ports. We
will need port 5060 open or we can provide other custom ports or VPN
services to provide voip services. If you have more than one voip

5060 for line 1, 5061 for line 2 and so on.

configured the device properly (optimal). We recommend that we
auto provision your device remotely. You will need to enter the
profile path in your device and our server can automatically setup
the device for you.
for business class services, we will need to ensure your equipment
will be able to handle Qos (Quality of Service).
We recommend linkys or cisco routers with Qos. With QoS enabled,
the router will manage all your internet traffic and will prioritize
ip packets based on order of priority. It will give applications
like VoIP higher priority and ensure your call quality is always
good and consistent.

bandwidth and supports dtmf (for dial tone access to
applications like calling card, pc phone banking). You will need fax
codec t.38 support if you plan to receive faxes on your phone
number. If your did carrier has oversubscribed their channels, you
may get a busy signal or experience network congestion.
If you are
using your own vendor for termination, please ensure their codec and
carriers are configured properly and are not using poor quality
carriers. Long delay in connecting can be due to latency in
connecting to carriers among other factors.
VoIP Switch is not codec dependant and does not alter your codec.
Your inbound and outbound carriers must be compatible with your end
user device codec settings or you may experience one-way audio and
call drop problems.
