[Users] uac_auth cseq workaround - ANY ?

Hi Gerry,

not incrementing the cseq number during authentication is a known 
limitation of the uac module. A solution will require dialog persistence 
on server (cseq number spreads across the entire dialog) - and this is 
only in the early stages....:(
I'm afraid there is no work around....

regards,
bogdan
