Ringing tone generation
We have a problem with 22.214.171.124 SAP BCM version. For some external calls there is no ringing tone played for the agent.
We are using SIP trunk for outgoing calls.
I have checked the tcpdump of such call and there is only 180 Ringing sent to BCM. No audio channels are opened until call is answered. As BCM is last SIP endpoint then it should generate ringing tone to agent when Ringing is received.
There are options in Global Switching Settings to enable ringing tone in CDT for all outgoing calls. That is not a solution because then on most calls agent will hear double ringing tone or ringing+busy at the same time.
Another option is to use MRS ringing tone for that specific trunk but that will result also double ringing tone for most of the calls.
Can anyone comment this from SAP side?
