Our HMP application receives incoming calls over SIP (connection A).
Sometimes these calls are connected to an IVR computer.
For the IVR connection a second SIP call is made. (connection B)
Both SIP calls are connected to each other. Voice goes from A to B and from B to A.
The DTMF is using RFC2833.
Should HMP automatically sent the RFC2833 events from A to B when the voice is connected as described above? Do you have to configure/enable this?
I have also tried to detect the received DTMF events.
When HMP makes a call to a SIP device, I see GCEV_TELEPHONY_EVENTs from the called SIP device.
But when the SIP device makes in incoming call a I do not get these GCEV_TELEPHONY_EVENTs from the calling SIP device.
When I make a wireshark trace, I see that these RFC 2833 event are sent by the SIP device. Why is HMP not generating GCEV_TELEPHONY_EVENTs for it?
