[Freeswitch-users] DTMF Star Event Inconsistent

Thanks. I am not bridging any call. Calls are originated via the socket interface to the extension 1003. And for the same call, all digits except star will produce two events while star will produce one event sometimes and two events some other times in the same call.

Here are for instance events i got in one single call, pressing 5** (five, star, star). You see that 5 produced two events, the first star produced one event, and the third star produced two events.
