[OpenSIPS-Users] Branch Versus Fork

 When you are referring to forking in SIP, you probably should use the
term "parallel forking". This occurs when you are trying to complete
several "branches" all at once. A branch can also be called a call
"leg". By default, when you t_relay() a call, it will go after each
branch all at the same time (parallel fork). Sometimes this is not the
desired behavior, and instead, you want to try each branch one at a
time. You can do this with the serialize_branches() function,
