You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Summary | 0002543: Call registrations fail with h.323 phone systems | ||||||||||
Description | When using certain VOIP h.323 phone systems, call registrations fail during the h.245 negotiation stage. This occurs both on connections from the Blue network and LAN to LAN VPN connections. The problem is quite bizarre, one or two packets are dropped but when resent the packets pass through, the packets dropped (tcp) are mid stream. Some PABX systems seem to either timeout (very quickly) or ignore resent packets. The solution is to remove the nf_nat_h323,nf_conntrack_h323 modules from the kernel with modprobe -r at boot time. This most likely will break h323 across the public internet, affecting programs such as net meeting but atleast H323./H.245 VOIPS works | ||||||||||
