Talkswitch 48-CA User Manual page 126

Suggested setup:
Plug the 4 highest traffic lines into unit 1. Also connect the 8 highest phone usage
employee extensions to unit 1. Next, connect the remaining lines and extensions
to unit 2. Make sure you leave the 'Hunt lines on same unit first' option enabled in
the Line Hunt Group section of the software. This arrangement keeps most of the
traffic on unit 1 and any outbound calls made from any extension will usually go
out on the same unit the extension is connected to. The same will apply for
inbound calls forwarded to Remote Extensions. The call will be forwarded out on a
line belonging to the same unit that the call came in on. Only if a line on that unit
is unavailable will the call be forwarded out on a line on the other TalkSwitch unit.
Problem: Calls across the LAN are lower in volume
•
Check the line gain levels on the Audio Controls page located in the 'Options' folder
in the TalkSwitch configuration software. You may need to boost the Line gain levels
on one or more lines to compensate for high loss lines. Take note that if these
controls are set improperly and your lines are problematic, you may hear an echo
when calls are made across the LAN.
Problems that may occur with VoIP
Problem: I hear re-order tone when I try to dial a VoIP location.
•
Confirm the number dialed is actually part of the VoIP group (i.e. registered with the
same Proxy/Registrar server as your TalkSwitch CVA, SIP gateway or SIP phone is
registered with.
•
Check that TalkSwitch has all proper settings in the IP Configuration and VoIP
Configuration pages
•
Contact TalkSwitch for help at 888.332.9322
Problem: Callers complain the sound is distorted or choppy.
•
Your broadband connection may not have enough upstream bandwidth to support
many simultaneous VoIP calls. In the 'Options' section under 'Audio Controls', you may
need to disable the G.711 and G.726 codecs and only use G.729.
•
You may have too much data traffic on your Internet connection at the same time
you are trying to make voice calls. We suggest that you use a router that supports
QoS (Quality of Service) for VoIP.
Problem: When I call someone or they call me, voice is only heard in one direction
•
The cause of this problem is usually a result of a router being misconfigured with
respect to port mappings. Ensure all required VoIP ports are mapped to your
TalkSwitch unit. Also, ensure you use a static private IP address when connected to
your router as this can also affect port mappings from the firewall/router.
