[SIPForum-discussion] TO HEADER

[雨 陈]

Hi Arijeet,
   
  As far as I am concerned about the RFC3261 section 8.1.1.3 ,it give us three examples about the FROM head field which is similar with TO:
  1.From: "Bob" <sips:bob at biloxi.com> ;tag=a48s
2. From: sip:+12125551212 at phone2net.com;tag=887s
3.  From: Anonymous <sip:c8oqz84zk7z at privacy.org>;tag=hyh8

  With all due respect, I think the display name can be quoted or not ,and the '<' ,'>' is optional.Furthermore, as the practical data I had got, the SIP-I msg alway be used in the NO.2 way, that is to say, the format likes Tel URI without quote.
   
  Regards
   
  Nora

  Hello Nitin,
   
  1. According to the standards(e.g. RFC 3261), display name has to be a quoted string. So your 2nd example is correct in this context. The first one may not be.
   
  2. The uri is present within "<" and ">". This is correct too. If you have a display-name then the uri should be wrapped up in these [RAQOUT & LAQOUT].
   
  3. However I am not sure about the presence of the "#" character in your uri part [not the display-name]. This ideally should be present ONLY as an additional part - as an association of an URI (not a part) in order to denote a fragment (especially required when retrieving a document). In the current example it does not seem (to me) to be in the correct place. I would request you to consult RFC 2396 in this context and double-check.
   
  Happy hunting.
   
  Thanks and Regards,
  Arijeet
