[Freeswitch-users] On-conference distortion for FreeTDM channels, but not SIP channels

[Anthony Minessale]

That's why my recommendation was to develop a mod_freetdm timer instead of
dahdi timer so you could abstract the timer into the freetdm and develop t1
timers for any and all rather than one.
A workaround would be to use sangoma cards in dahdi mode then use the
proposed dahdi timers.
