I have a server that has Freeswitch (1.0.5.pre9) a Sangoma A101 (E1/T1) and Analog A200 cards using OpenZap. The cards are connected. The wanrouter version is 3.5.8.6 as the newer version didn’t work for us yet. Also trying to test with the FS trunk but having other wanpipe driver issues.

I have a question about using the A200 card. The intent is to hook up FAX machines to the two FXS ports. The desired behavior is the first call goes to the first FXS port one, and while port one is busy a second call goes to the second port.

In the Freeswitch dialplan there is a statement to bridge to FXS port 1 and if that fails then bridge to FXS port 2. However, the first bridge never fails even when it’s busy. I notice the A200 card supports call waiting. The FS debug messages show that is what is happening.

Question: How do I disable call waiting on the A200 card when used with OpenZap?

I am not sure about whether the hangup_after_bridge=true and continue_on_fail=true are necessary or in the correct spots. I’ve tried calling with these statements present or not and moved after the first bridge but doesn’t appear to affect the status of the first bridge statement.

Question: Are the hangup_after_bridge=true and continue_on_fail=true statements necessary and in the right spot?

Dialplan statements:

Debug statements for second call to FXS/1 extension:

(Notice that several of statements mention CALLWAITING.)
