Hi Daniel,

 

I already use the select for getting the contact, but I still got the error as it happens before the fist line of my failure_route :

Hello,

the Contact header body looks ok, using comma to separate many contact values is ok.

My guess is that {to.body} transformation is used in this case, it is not coming from core or a module. The To header cannot appear many times, thus the transformation is throwing error in this case. If I am right with my guess, a solution is to plug {s.select,0,,} transformation before use of {to.body}. The index of s.select can be a variable, in case one needs to get all contact values, a while loop can be used.

Cheers,
Daniel

Hmm, it's a tricky one, not sure actually.

The answer might be in:

Even if the "display-name" is empty, the "name-addr" form MUST be used if the "addr-spec" contains a comma, semicolon, or question mark.

Aren't the Contact params supposed to be delimited by semicolon?

Hello,

 

I see parsing errors on 302 contact header that seems compliant to RFC :

 

Contact:<sip:172.16.0.21:5060>;q=0.5,<sip:172.16.0.22:5060>;q=0.25

 

<core> [core/parser/parse_addr_spec.c:479]: parse_to_param(): invalid character ',' in status 27: [;q=0.5]

 

Is there an error in my contact or is it truly a parsing error ?

               

Regards,

David
