Bridging from PSTN to VoIP
When you make a PSTN (TELCO) call to the X6v in PSTN to
VoIP bridge mode, you are connected to the VoIP service that is
connected to the X6v. This is like being connected to a
switchboard when you call a company or government office.
Unlike the case of a company or government office switchboard,
however, you are not limited to dialing extensions. You can dial any
call that your VoIP service supports.
This can offer a useful and convenient way to make free or low
cost VoIP calls from your X6v even if you are out of your home or
office. For example, you can make a local PSTN call to your X6v
from your cell or mobile phone, and bridge the call to a low-cost
long distance or international call via VoIP. Often this will save
considerable amounts of money compared to making the call
directly.
• Suppose you live in London, and you have friends and
family in Calcutta. You don’t have to be at home in order
to call them. You can call your X6v's PSTN phone number
from any standard phone including your cell phone, and
make a low-cost VoIP call to Calcutta.
• Suppose your company has offices in Dubai and in Buenos
Aires. You can set the X6v so that when customers call the
Dubai office after hours, the X6v automatically bridges the
call to Buenos Aires, and staff can answer the call in that
office.
• Again, if your company has offices in Dubai and Buenos
Aires, you can set up an X6v in bridge mode in each
location. Staff off site in Buenos Aires can call into the
PSTN number of the X6v in the Buenos Aires office and
make a VoIP bridge call to the VoIP number of the X6v in
Dubai. Once connected to the X6v in Dubai, they can
bridge to the PSTN connection in Dubai, and contact
customers and vendors outside the office in Dubai, all for
the cost of a local call in Buenos Aires. You can set up a
double bridge in each direction. In this way, calls can also
be made in the opposite direction, from Dubai to Buenos
Aires.
