'Setting a call on hold via PJSIP > FritzBox waiting music not playing
I have a question about the following method of the PJSIP library for a Swift telephone app:
pjsua_call_set_hold
https://www.pjsip.org/pjsip/docs/html/group__PJSUA__LIB__CALL.htm
When I set a call on hold with this method, my FritzBox should play a waiting music which is not happening. I'm now struggling to find out if it's a problem of the FritzBox or of the library.
Has somebody worked with this lib already and can share some knowledge?
