if this is a bridged call you will get one on each leg as the dtmf passes from one leg to the other. if in some cases the dtmf is intercepted by something like the bind_meta_app then you may only see 1. On Mon, Oct 27, 2008 at 11:36 AM, Klaus Teller <klaus.teller@gmx.net> wrote:
I do indeed look for the Event-Name attribute. But since for a single DTMF digit two events are received from Freeswitch (with Event-Name: DTMF) , i need to differentiate them somehow such that one is processed and the other ignored. The differentiation pattern i found is the channel state (CS_EXCHANGE_MEDIA or CS_EXECUTE state). But then, DTMF-star doesn't always have these two states.

you should be looking for the DTMF event and not reacting to any others
Event-Name: DTMF
any other ones are not necessarily related to what you want.

Hi,
I'm calling a registered soft phone (ext. 1003) via the event socket interface. That is, on one side i have some Java code connecting to the Freeswitch event socket interface and placing calls and on the other hand i have the soft phone registered to Freeswitch and awaiting for calls.
Now, when i get a call on the soft phone, i press a sequence of DTMF digits. The sequence of DTMF digits is intended to be read by the Java code via the socket interface. Most things run pretty smoothly: i can place calls, i can send DTMFs, i can receive them on the other hand.
The inconsistent behavior i'm seeing is following. For DTMF-0 to DTMF-9, and DTMF-#, i receive two events via the socket interface. The first one is in CS_EXCHANGE_MEDIA state and the second is in CS_EXECUTE state. Yet for DTMF-* i receive inconsistent number of events: sometimes only one single event in state CS_EXCHANGE_MEDIA sometimes two events as in the case of other DTMF digits.
It seems there is a pattern in this "inconsistency". The odd DTMF-* (first, third, fifth, etc.) generate only one CS_EXCHANGE_MEDIA event while the even (second, fourth, sixth, etc.) generate both events.
Can somebody help me understand what's going on?
Thanks, Klaus.
