Re: TekTalk Voice Codec It's a common issue in Linksys SPAxxxx adapters called talk-off and there are some tweaks that can help with it. However since TSI controls the configuration, they are the ones that need to apply it.

Ha! My wife has been complaining about this recently. She often hears it while talking with her mother. I've never experienced it though. Good to know it's actually happening to others as well.
It would be great to get this addressed.
The settings they need to change are:
DTMF Process INFO = No
DTMF Process AVT = No
DTMF Tx Method = InBand
