Site D calling Site C
1. Dial 9,15077175662.
2. “9” gets outside line. On some PBXs, an “8” may be used to direct
calls to the VOIP, while “9” directs calls to the PSTN. However,
some PBX units can be programmed to identify the destination
patterns of all calls to be directed to the VOIP.
3. PBX at Site D is programmed to divert all calls made to the 507 area
code and exchange 717 into the VOIP network. (It would also be
possible to divert all calls to all phones in area code 507 into the VOIP
network, but it may not be desirable to do so.)
4. The MVP2400/2410 removes the prefix “1507” and adds the prefix
“101#” for compatibility with the analog MultiVOIP’s phonebook
scheme. The “#” is a delimiter separating the analog VOIP’s phone
number from the digits that the analog VOIP must dial onto its local
PSTN to complete the call. The digits “101#7175662” are forwarded
to the Site B analog VOIP.
5. The call passes through the IP network (in this case, the Internet).
6. The call arrives at the Site B VOIP. This analog VOIP receives this
dialing string from the MVP2400/2410: 101#7175662. The analog
VOIP, seeing the “101” prefix, uses its own channel #1 (an FXO port)
to connect the call to the PSTN. Then the analog VOIP dials its local
phone number 7175662 to complete the call.
