Hi, I have checked in the first three patches there are some problems with the h245 patches with MSVC. It does not like declarations inside functions like + h223_pending_olc *pend = g_hash_table_lookup( h223_pending_olc_reqs[pinfo->p2p_dir], GINT_TO_POINTER(temp) );
Indeed, sorry about that. Here's a corrected version of the h.245 patch. Richard -- Richard van der Hoff <richardv@xxxxxxxxxxxxx> Systems Analyst Tel: +44 (0) 845 666 7778 http://www.mxtelecom.com
