This is my first post in this forum and I’ve just started to dabble with asterisk@home since 2 weeks ago, so pls forgive me for my shortcomings.
Just to let you guys know what I’ve done so far, I am using a TDM400 ( 1 FXO and 1 FXS, which i presume would make it a TDM11). However, I am currently using 1 channel only, which is loaded with a FXS device. I called it ZAP/1. I’ve also configured 2 SIP channels, SIP/1001 and SIP/1002. All channels are for internal use, and I haven’t configured PSTN connections yet. I am planning to add another ZAP channel, but I have to clarify some matters first.
Right now, I just need some clarification on the instance of the ZAP/1 channel. I’ve come to understand one zap channel can have 3 instances.
So what is the use of this instance?
Can I make use of this instance ( eg. ZAP/1-2 ) instead of creating a new ZAP channel?
If I can’t do that, then is it possible for me to forward the call immediately from ZAP/1-2 to ZAP/2-1?
Is there any way I can disable the Zap channels from automatically redirecting the incoming calls to ZAP/1-2 when the line is in use? Meaning I will get a busy tone, instead of a ringing tone.
Thanks in advance for your assistance. It would be great if you can provide me some links for further readings on this issue. I did not get much help from voip-info.org regarding this matter.
