By the way, if you use Vc2400A-16s/8o, and you donot know which RJ11 port is used to connect the PSTN line or analog phone, you can check the module number beside the module firstly, then find the corresponding RJ45 port.

If the RJ45 port have the FXS modul and FXO module at the same time,  you can try to connect the analog phone to the RJ11 port, after that, you can login the web page of elastix, and check if the port is detected.

If the RJ45 port just has the FXS module, you just need to plug the analog phone to the splitter, after that, you can check if the elastix detects it.

If the RJ45 port just has the FXO module, you just need to plug the PSTN line to the splitter, after that, you can check if the elastix detects it.

 

If you have the splitter from our company, you can refer to the below method:

​After you plug the splitter to the RJ45, you can separate two pins firstly, the pin which is away from PCI-E is FXO 1-2.
 
In the pin(FXO 1-2), when you plug the RJ11 line, you need to make sure the small hole is below the RJ11 port, and the RJ11 port which is away from PCI-E is FXO 1, and the rest RJ11 port is FXO 2.
