Snom phones use the line parameter to identify for which of the multiple lines 
is the target of the incoming request (otherwise it is impossible to identify 
the line, if you have multiple lines with the same username at different 
proxies). URI parameters are completely legal, although they are 
unfortunately too often dropped by proxies (luckily not by SER).

I would suggest, that you check at the web interface of the snom phone, if the 
phone receives the request at all.
