We try to keep H323plus, ptlib version agnostic. Looks like that was one we missed. I have just commit a fix to the CVS.

I also have not found any note about this in mailing list. Does anybody ran into same problem ? Best regards, Vladimir Fekete P.S. I'm testing different versions of ptlib/opal/h323plus because I'm trying to find release code of h323's h.264 video codec which would run with opal without problems
