| AC Termination |
| Selects the impedance of the analog line connected to the FXO port on the GXW410x. Here is |
|
| Impedance |
| some basic information which may be helpful for initial configuration: |
|
|
|
| 600 Ohm – North America; |
|
|
|
| 270 Ohm + (750 Ohm 150 nF) |
|
|
|
| 220 Ohm + (820 Ohm 120 nF) – Australia, New Zealand |
|
|
|
| 220 Ohm + (820 Ohm 115 nF) – Austria, Bulgaria, Germany, Slovakia, South Africa |
|
|
|
| 370 Ohm + (620 Ohm 310 nF) – UK., India |
|
|
|
| If this parameter is not configured properly you may experience echo or static in the line. Please |
|
|
|
| refer to Table 9 (FXO Lines Test Tab Definition). This tool will run an automated test to |
|
|
|
| determine the correct impedance value to match your lines |
|
|
|
|
|
|
|
|
|
|
|
| Wait for |
| Default is Yes. When set to Yes, the gateway will recognize |
|
|
|
| (CO) before it completes call. If you can’t make an outbound call, set this is No. |
|
|

|
|
|
| Stage Method |
| Syntax - |
|
|
|
| Stage method can be set to either 1 or 2. |
|
|
|
| Set this parameter to 1 if you need to make a direct PSTN call from a VOIP endpoint. When you |
|
|
|
| set it to 2, you will first dial one of the VOIP channel accounts from the VOIP endpoint, this will |
|
|
|
| result in getting a PSTN line |
|
|
|
| Most implementations require this setting to be configured to 1. |
|
|
|
|
|
|
|
|
|
|
|
| Min. Delay before |
| Default is 500ms. This needs to be equal to or greater than the Current Disconnect threshold |
|
| Dial PSTN |
| setting. Once the threshold is reached the gateway can dial out. This parameter should only be |
|
|
|
| used if there are PSTN line detection issues. |
|
|
|
|
|
|
|
|
|
|
|
| Unconditional Call |
| This is an extremely important setting to make sure incoming PSTN calls are picked up and |
|
| Forward to VOIP: |
| forwarded to the correct VOIP destination. |
|
|
|
| User ID - This parameter allows users to configure a User ID or extension number to be |
|
|
|
| automatically dialed upon FXO line |
|
|
|
| SIP Server - You also need to specify the Profile of the user id configured above (p1 stands for |
|
|
|
| Profile 1, p2 stands for Profile 2 and so on). |
|
|
|
| SIP Destination Port - Along with the |
|
|
|
| the destination port where you would like to send the call. By default it should be set to ch1- |
|
|
|
| x:5060; (x can be 4 or 8 depending on number of ports). |
|
|
|
| We can also specify a different destination for each port. For example under User ID we can |
|
|
|
| type in: |
|
|
|
| Under Sip Server we can type in: |
|
|
|
| Under Sip Destination Port we can type in: |
|
|
|
|
|
|
|
|
|
|
|
| Number of Rings |
| Default is 4. This is the number of rings the gateway will wait to send the call to the |
|
| Before Pickup |
| VOIP side in case the Caller ID has yet to be detected. If there's CID information the |
|
|
|
|
| |
|
|
| call will be sent right away. If your lines don't have the CID service set this to 1. |
