uniden 9135 answering machine does not answer calls with SPA 3102
Have just bought a Uniden 9135 DECT phone sytem with answering machine.
I have a SPA 3102 which is set up tp pass the PSTN calls through so that the handset receives both VOIP and PSTN. When I connect the phone to the SPA 3102 it the phone rings and the (PSTN) calls can be manually answered but if left for the answering machine to answer it does not pick up and the call rings out and disconnects after 6 rings.
The answering machine works if it directly connected to the PSTN line (and the PSTN line is not connected to SPA 3102)
The other thing I have noted is that the visual ring light is always flashing when connected to the SPA 3102 but doesn't flash when connected to PSTN.
I'm located in Sydney Australia and my VOIP Provider is Engin.
