PEER-PEER GATEWAY SCENARIO
1.Extending analog lines using FXS & FXS SIP server
This scenario allows an organization to communicate with a another organization through IP network.
In this diagram, FXS gateway A will assign extensions 8001-8008 to 8 analog phones. FXS gateway B will assign extensions 7001-7006 to 6 analog phones. All analog phones can communicate with each other via extension numbers.
Configuration / Operation
| device | IP | analog phone | |
| A | FXS | 172.16.6.61 | 8001-8008 |
| B | FXS | 172.16.6.56 | 7001-7006 |
1.1: Turn on the self Switch button
Turn on the self Switch of A and B
1.2: Configuring extension numbers
Click channel extension setting in A and set the internal extension number to 8001-8008.
Click channel extension setting in B and set the internal extension number to 7001-7006；
1.3: Configure routing rules
A
B
2.Extending analog lines using FXS & FXO sip servers
This scenario allows an organization who only has FXS ports to access the FXO ports through the IP network.
In this diagram, FXS gateway A will assign extensions 8001-8008 to 8 analog phones. FXO gateway B has PSTN lines. With the help of ip infrastructure and FXS A and FXO B, analog phones 8001-8008 connected in FXS A are able to make, as well as receive calls from FXO B.
Configuration / Operation
| device | IP | analog extension | analog pstn | |
| A | FXS | 172.16.6.61 | 8001-8008 | – |
| B | FXO | 172.16.6.56 | – | 070512345 |
1.1：Turn on the self Switch button
Turn on the self Switch of A and B
1.2：Configuring extension numbers
Click channel extension setting in A and set the internal extension number to 8001-8008.
1.3：
Configure routing rules
A
B extension
B outbound route rules
B inbound route rules
Test
– Once setup is complete, please verify as follows.
– FXS A extensions dialing each other
For example, if an analog phone on FXS-1 dials 8002, the analog phone on FXS-2 will ring
– FXS B extensions dialing each other
For example, if an analog phone on FXS-1 dials 7002, the analog phone on FXS-2 will ring
– FXS A and FXS B dial each other’s extensions
For example, if the analog phone on FXS-1 of device A dials 7001, the analog phone on FXS-1 of device B will ring
– FXS A and FXO B dial each other’s extensions
For example, if a cell phone number is 12345, the analog phone on FXS-2 of device A dial 712345, and the cell phone will ring; if the cell phone dials the analog outside number (070512345) on device B, the analog phone on FXS-2 of device A will ring.
