Hi Barry,
indeed, there is a problem with this Nero SIPPS IP Phone - even if it receives vsf=AAAAAAAAAAAfGgQRSQADBEkACyVdABUuaW1hZ2luZS5pZQ-- it sends vsf=aaaaaaaaaaafggqrsqadbekacyvdabuuaw1hz2luzs5pzq--
so, it is case insensitive. The parameter is B64 encoding, so it is case sensitive.
The RFC says that the a SIP UA must mirror unchanged all RR parameters disregarding if it understands them or not.
Just to update you, Nero have fixed this bug. Works fine now.
Thanks for the help
