An updated version of chan_ss7 for asterisk has been released as version 0.8.3. As a work-around to support overlapped dialling without the use of the dial plan to determine when the dialled number is complete, a configuration option t35 is introduced. For example, t35 => 4000,st means that the T35 timer has a value of 4000 msecs, and when it times out, an "end-of-pulsing" signal is assumed, and that completes the dialled number. chan_ss7 now generates in-band indications when no other indication source is detected.
