Example: You have 2 TalkSwitch units, 6 lines and 12 employees. The 6
lines have the Hunt/Rollover service from the phone company.
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, 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 Technical Support.
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.
