Hi,
I have a question with regards to the handling of the nua_i_refer event.
As indicated in the documentation, the application must get the refer
event (NUTAG_REFER_EVENT()) and the referred by (SIPTAG_REFERRED_BY())
pointers and pass these to the call to nua_invite to establish the
session to the refer target.
What I am wondering is what is the lifetime of these pointers before
they get released automatically by Sofia?
In particular:
1. Is it ok for the application to *not* call nua_invite in the
nua_i_refer callback handler, but instead store these pointers and
call nua_invite some time later from another entry point?
2. If the answer to 1 is yes, will the stack automatically free these
pointers after some time (through a timer)?
3. If the answer to 2 is yes, does Sofia generates an event so that
the application can tell if these pointers have been freed?
Many thanks for your assistance,
Olivier.
