[Freeswitch-users] pass_rfc2833 in 1.4.15

Hello, Have there been any know issue with the variable pass_rfc2833? We recently upgraded to 1.4.15 and are facing some DTMF issues. Before on 1.2.13 we also had issues with DTMF, so I added the pass_rfc2833 variable, and the problems went away. Now again with 1.4.15, the variable is still enabled, but the problems happen again. Any ideas? Grant
