Appendix C--- Dynamix 2504 (FXS-04) and Dynamix 2540(FXO-04) in peer to peer mode with hotline by port to port application. Purpose This paper is going to describe how to configure FXO to FXS in peer to peer mode with hotline function to link from one desire port at FXO via SIP IP link to remote FXS desire port. This application is widely used to extend traditional PABX extension from one location to remote office via IP Link which could be VPN, Private network, fiber link or Wireless network.

PAGE 66
Figure 6. Step 7: set Dynamix 2540 FXO number and IP address on FXS gateway’s webpage Dialing Plan Phone Book. See Figure 7. For example: the Dynamix 2540 FXO port 1 number is 1001, SIP local port is 8080. The FXS gateway’s phone Book format is as follows. FXO_line_number@FXO_ip_address:sip_port number. At this example, the FXS gateway phone book should configure four ports as follows. Port 1 configure to 1001@192.168.23.23:8080 Port 2 configure to 1002@192.168.23.23:8080 Port 3 configure to 1003@192.168.

Dynamix 2540 (FXO Gateway) configuration Step 1: set static IP address to Dynamix 2540 FXO gateway’s WAN port as following picture. See Figure 8. For example: Set static IP address 192.168.23.23 on Device Setting Network of Dynamix 2540 WEB page. Figure 8. Step 2: Go to VOIP Setting  SIP to select the “Accept Proxy Only” feature to NO and make sure to setup the SIP Local Port number to 8080. See Figure 9. Figure 9. Step 3: Set the FXO SIP line’s information to each line.

Select “2 Stage Dialing” at “DNIS is Register TEL” webpage. When user picks up the handset from FXS port #1 of Dynamix 2504, you should hear Dial Tone from PABX extension 201 which was connected to FXO Line #1. And it works like this analog phone was connected at remote PABX’s extension 201. See Figure 11.

Step 5: Set Route Plan to each FXO line. Disable the “VOIP Default Route” first. Figure 12. Set the Incoming Call Type to VOIP; Matched Prefix number from 1001 to 1004; Matched Length to 0 and Outgoing Type to FXO. See Figure 12. For example: Configure Route Plan to each line of FXO Gateway. a. Line #1 of FXO Gateway setting, see Figure 13. An FXS port 1 incoming call routes to FXO port 1 configuration example.

Figure 13. b. Line #2 of FXO Gateway setting, see Figure 14. An FXS port 2 incoming call routes to FXO port 2 configuration example. Incoming Call Type : VOIP Matched Prefix : 1002 Matched Length : 0 No Answer Timeout : 30 (MUST be longer than 10 seconds). Outgoing Type : FXO Hunting Type : selected anyone. Routing List : 01. Line 2 ; 02. None. ; 03. None ; 04. None. Figure 14. c. Line #3 of FXO Gateway setting, see Figure 15. An FXS port 3 incoming call routes to FXO port 3 configuration example.

Figure 15. d. Line #4 of FXO Gateway setting, see Figure 16. An FXS port 4 incoming call routes to FXO port 4 configuration example. Incoming Call Type : VOIP Matched Prefix : 1004 Matched Length : 0 No Answer Timeout : 30 (MUST be longer than 10 seconds). Outgoing Type : FXO Hunting Type : selected anyone. Routing List : 01. Line 4 ; 02. None. ; 03. None ; 04. None. Figure 16.

4. Configure incoming Ring Cadence to FXO Gateway When you connect Dynamix 2540 FXO gateway Lines to local PABX’s extension or PSTN switch, please go to Dynamix 2540 webpage setting at VOIP Advance  Ring to configure proper Ring Cadence ( Ring ON time and Ring OFF time ) according to the PABX or PSTN ring Cadence specification. Without configuring Ring Cadence to FXO gateway properly according to PABX or PSTN Ring Cadence, FXO may detect Ring signal in a strange behavior and cause abnormal operation.

See Figure 18. Step 2: Go to FXO Gateway webpage configuration at SIP Trunk  Modify SIP Trunk to enable Outgoing Caller ID with both Display Name: PSTN Caller ID and User ID: PSTN Caller ID as following Figure 19. After this configuration, FXO gateway send detected Caller ID signal from PABX or PSTN Lines to remote FXS gateway. There are additional two options at Display Name and User ID to select what number are going to send to remote FXS gateway. Here are summary of three options. a. b. c.

See figure 19. FXO Gateway Caller ID Mode. Figure 20. FXO Telephone Number. Step 3: Enable Caller ID generation at Dynamix 2504 FXS gateway. See Figure 21. Go to FXS Setting  FXS Line  Caller ID Mode to select Transparent to enable Caller ID generation. After enable this command, analog telephone set is able to display Caller ID either FXS phone number (at this example, they are 501 to 504) or display number which were sent from FXO gateway ( PSTN, SIP Trunk or FXO Line number).

Step 4: Select FXS gateway’s Caller ID Mode. See Figure 22 and 23. FXS Gateway Caller ID generation is able to configure which Caller ID mode in order to match analog phone set’s Caller ID specification. Go to FXS Setting  Caller ID  Caller ID Mode to select one of Caller ID Mode ( DTMF, FSK Bellcore, FSK ETSI, See Figure 23 ). There are other options you may need to pay attention at Polarity Reverse Before Caller ID, Dual Tone Before Caller ID, Caller ID Present, DTMF Caller ID start and stop digit.

6. Release FXO Line from PSTN or PABX extension after call was dropped. FXO analog interface detect disconnect tone which was sent from PABX extension or PSTN line to release tip/ring phone wire. In other word, the FXO line can only drop call after detect an effective disconnect tone. In FXO gateway webpage configuration, Go to VOIP Setting  Tone to configure Disconnect 1 and Disconnect 2 in which disconnect tone are needed to match with PABX or PSTN disconnect tone. See figure 24.

7. FLASH command generation and detection on FXO and FXS gateway. FLASH feature is widely used for PABX extension to implement PABX’s advanced features such as Call Transfer, Call Hold, Conference, Forwarding or Call Park and others. PABX relies on extension’s analog phone set to generate Flash time to inform PABX this is an FLASH command. In this FXO+FXS P2P Hotline application, FXS needs to detect a FLASH command from analog phone set and transmit to FXO gateway via VoIP network.
