Hi!
I have a system that sometimes has a problem getting DTMF to be properly decoded when calling outside numbers.
I never have a problem dialing, it is always when someone tries to type something as simple as an extension once the communication has been established.
The problem only happens occasionally and changing the DTMF mode doesn't appear to fix it...
It appears to be a timing problem as typing the numbers slowly seems to get them to register properly..
The phones are analog and they are connected to the PBX using a Sangoma A200 FXS module. As far as I can tell the card hardware DTMF decoding is activated (and so is the hardware echo canceller).
Does anyone have any idea what could be the cause of my problems?
Thank you very much and have a nice day!
Nick
