[SR-Users] '302 Moved temporarily' contact parsing error

[Daniel-Constantin Mierla]

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
