Hi Everyone, I've been struggling with 3CX for some time but have set it up to be linked with an existing Analogue PABX. I have two SPA-3102's 1x FXO 1 x FXS hooked up at our PABX end. The FXO's are connected to Interneral extension on the analgoue PABX and the FXS to TRUNKS on the PABX. Currently i have some calls routed to my house from the office, IE, Extension 218 rings at the office, the SPA-3102 passes the call to 3CX and my home phone rings.. And all is great! However, if I want to transfer that caller back to an extension in the office or stick them on hold (on the traditional PABX) I can not. Normally on an Analogue phone in the office walls you just punch in 11 and it puts the call on hold, but the Linksys SPA941 phone at my house when I dial 11 does nothing. I need the DTMF tones to be passed to the FXO port thats holding the call, and not the tones to go to the 3CX system. Has anyone done this or do you know the config? Thanks heap in advance.
