[SR-Users] failure in accessing r-uri params

[Daniel-Constantin Mierla]

Hello,

I expect it has to do with the special requirements on handling uri 
enforced by 'user=phone'. Something related was on sr-dev few time ago:

- http://lists.sip-router.org/pipermail/sr-dev/2013-December/022267.html
- http://lists.sip-router.org/pipermail/sr-dev/2013-December/022269.html

At that time I checked the sources and parameters are linked to another 
field in uri structure than without it, thus the params field is somehow 
left empty. I had no time to investigate more the specs, maybe looking 
at parse_uri() will shed more light.

Cheers,
Daniel
