Replace a call in PJSUA2: call::onCallTsxState() not called in state PJSIP_TSX_STATE_PROCEEDING when

[wosrediinanatour]

Describe the bug

Function call:onCallTsxState() was not called in state PJSIP_TSX_STATE_PROCEEDING and/or PJSIP_TSX_STATE_TRYING. The first call back is in state PJSIP_TSX_STATE_COMPLETED.

Functions call::onCallReplaced() and call::onCallReplaceRequest() were not implemented, but this should not be a reason.

• As far as I know, there is also no call::onCallTsxState() called for a new incoming INVITE. Would be good to add this information to the documentation of onCallTsxState() in call.hpp.
• Shouldn't be call::onCallTsxState() at least called in state PJSIP_TSX_STATE_PROCEEDING?

Steps to reproduce

Was not done with a example / test app.

PJSIP version

2.14.1

Context

This happens when Functions call::onCallReplaced() and call::onCallReplaceRequest() are not implemented.
Should be independent on OS and platform.
