[OpenSER-Devel] question about 302 message

[Watkins, Bradley]

You may want to follow Klaus' advice and use the q parameter.  You may
also want to examine the formatting of the first example in Section
20.10 of RFC3261.  It's possible that, barring a more lengthy
explanation somewhere else (which I haven't found in other RFCs at a
cursory glance), the UAs are being more pedantic about multiple URIs in
the Contact header.

Regards,
- Brad
