I have a Cisco 1861 Integrated Services Router with 4 FXS ports and 2BRI.
Well, as it is known, the FSX ports is for telephones, fax, etc.My deal is to connect the router to the PSTN network with a single RTC thru a analog port, but I'm not sure how it's possible because all of them are FXS.
As other hardware manufactures I worked on before, I could deactivate the FXS signal and start configuring as FXO, but i dont know how to make this on Cisco.
Can anyone advice me?
