I have a simple setup, an AEX800p card configured with 8 fxs ports. When you plug an analog phone into any of the ports and try to dial, no dtmf is heard. The line responds accordingly (dial tone just eventually times out).
I’ve tried setting dtmfmode=inband and relaxdtmf=yes in the global channel configuration to no effect. I’ve tried two different analog phones, one of which works fine on a different (grandstream) ATA. I’m sure this is something easy but I’m stumped.
Thanks in advance.
