[Serusers] To and From Headers - Angle Brackets Or Not

[Marian Dumitru]

Hi Paul,

Conforming to the grammar from RFC 3261, the brackets are required only 
if a display name is present or if you have uri parameters:
	"name" <uri>
	uri;param   <- param is header parameter
	<uri;param>   <- param is uri parameter
	<uri;uparam>;hparam   <- uparam = uri parameter; hparam = hdr parameter

Best regards,
Marian
