Random DTMF Tones Only on heard on ATA
I have a couple of Linksys PAP2T-NA & Grandstream HT-502 extensions that are
receiving random DTMF tones on their side, but that are not heard by the
outside party. I have been using Asterisk 1.6.6 through 1.6.10 and have
always had this issue. I am only using SIP on the Asterisk server and all
extensions and trunks are set to rfc2833; outside of this issue DTMF
operation works fine.
