[OpenSIPS-Users] sst min-se problem

Looking in the code, the 422 is sent only if the proxy min-se (1800) is 
smaller than the min(received-min_se(90), received-se(300)) -> 1800 < 90 
-> false, no 422.

But reading the RFC 4028, I would say the condition is the other way 
around - if the local min-se is higher than min(received-min_se(90), 
received-se(300)) , the 422 should be sent out.

Regards,
Bogdan
