[asterisk-dev] Issue with Parsing Contact Header without Brackets and with additional HeaderParameters seperated with semicolon

[bala murugan]

RFC3261 isn't exactly clear on this.  Section 20.10 implies that the
brackets are optional if a display name isn't specified but the ABNF
specified down in section 25.1 implies that they are required always

[Bala] I can see section 20.10 mentioned as optional , but in  ABNF section
25.1 i couldnt find it mentioned required always
please advise .

btw i am using chan_sip
