Globalink VoIP Service Technical Requirements |
|
Since our phone
service using VoIP (voice-over IP or internet), you will need a good
internet connection in order to provide phone service. You can download
pingplot to test your internet link time or you can test now using
this link.
While you may be
able to connect without following all the requirements, you may need the
following in order to enjoy the best call quality.Please review
our requirements below in order to provide you the the highest
quality service.
-
You will
need sufficient internet bandwidth (in addition to the other
applications running on your computer or network) to provide phone
service. Depending on your codec, you will need 64k up and
down bandwidth per line.
-
For best
results we recommend an voip device like Linksys PAP2T or SPA 941
voip phone as softphones may not work properly if your computer
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).
-
Internet
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
device in the network, you will need additional ports open example
5060 for line 1, 5061 for line 2 and so on.
-
Device is
setup correctly. Please follow our setup to ensure you have
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.
-
Please note
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 enable,
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.
-
Codec
setup. G711 is best. Free softphones may not have the necessary
codec for good call quality.
-
If you using
third party did or
phone numbers, please ensure your provider has sufficient
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.

tips.
