[SIPForum-discussion] Option tags in "Supported" Header

[XIAO Xiaohong]

hello
Rfc3261 section 8.1.1 clearly says "Extensions defined by experimental and infromational RFCs 
are explicitly excluded from usage with the Supported header field in a request,... ".
So I think the answer to your question is NO.
 
 
If a request insitsts on inserting a un-standard option in the "Supported" header, I think remote party
shall ignore it.

Subject: [SIPForum-discussion] Option tags in "Supported" Header



Hi, 

Is it allowed to have an optional tag starting with "x-" (e.g., x-myOwn-param) in "Supported" header, here x- indicates experimental.

I am trying to understand, how the other party from the public side of the network accepts it, read it and ignore if not required and continue processing the request. Or is it not allowed to have any option-tag other than published in RFC3261 (such as 100rel).

Appreciate any responses. 

Thanks 
Sreeni
