This arrangement piggy backs 2 PABXs together.
You get these features:-
Free calls to the other office in general
To do this, one office simply presses line 4 and it immediately
rings on line 4 in the other office. The call is free.
Free calls to the other office in Particular.
To phone a particular extension in the other office simpy press
the button marked "ext 301" When you hear the other office dial tone
dial the extension number you require. The call is free.
Transfered, brokered calls to the other office.
Say you have a caller on the line who wants speak to someone
from your other office.
Simply press ext 301, dial the person
you want to speak to in the other office and transfer the outside caller to him.
Remote answering service.
Say you are short staffed and want your
other office to answer some of your calls. Simply program you system
so that when calls in general come in on your lines, they also ring at
the remote office and they can answer for you. It could be set up so
anyone you choose could do this, not just your other office.
Host the other office.
If required, the other office could make their
calls from your office pabx. This could be good if they need to make
calls local to you but long distance to them.
OFFICE ONE AND TWO: In this example, The two offices mirror each other, each
having a KVA300
Any system phone could be set with a DDS button for Extension 301 and a Line
Selection button for Analogue Exchange line port 4.
When making a call, the PBX user could press line 4, thereby getting voip Dail
tone and being able to phone any VOIP number including that of the other
office's line 4.
Alternatively the PABX user could press the button for ext 301 and get
internal dial tone from the other office and then either dial the required
extension or, if allowed, make an outside call from the remote office by dialing 9.
These offices would work the same even if they were in different countries.
Your sites will need a router with a spare port and
It most cases, there is nothing more to do than connecting it and the
system will work fine.
The voip calls make use of the unused bandwidth on the router and so the
calls are free of charge. 1 line usually works very well even on the minimum
bandwidth of 512K. Should your customer be using up the bandwidth with
large file transfers then in practice, they may suffer temporary speech
degradation during occasional file transfers. If they do not already have
one, they can prevent this by getting a router which allows you to reserve
bandwidth for speech. If they expect to use 2 speech channels regularly,
then they may need to rent more bandwidth.
Note, although we set up the adapters, we do not setup the routers. Having
said that, in most cases with small business, their routers have DHCP
enabled by default which means they auto detect our adapters without the
customer or you having to do anything to set them up.
