I got a Quadro2x that uses 2 CO
the Quadro2x has Boot loader: 4.0.8 and Firmware Version: 4.1.33
First CO goes to FXO 1 (PSTN provider HELLMEX (TELMEX)
second CO uses a Linksys SPA3000 to the PSTN (sign on at quadro2x at IP line 8 (also with Telmex)
the system works great it can receive and make calls from the FXO and to/from the spa3000 (with call routing at the quadro2x and some tweaking at the spa3000 PSTN line settings)
but no CID on FXO or SPA3000 (ip line 8)
please help.
