[reSIProcate] DeprecatedDialog and INFO Messages

[Peter S]

The DeprecatedDialog header file contains methods to build Inivte,
Bye, Refer, Cancel etc. But it does not have a function for making
INFO mesages. Should I use the
   SipMessage* request = makeRequestInternal(INFO);
   incrementCSeq(*request);
or there is an easier way to look for the info.
Went through some of the files and examples in the Test code to find
the answer. Any other good pointers where I can get the relavant
infomation.
P.S.
