[Serusers] Call Admission Control on SER

[Francesco Botta]

Ok...maybe is better derive this kind of information from the CDR origineted from SIP/DSS-1|ISUP gateways  (for the inbound to outbound calls)....IMHO, B2BUA have too issues with scalability, robustness and transparency....do you agree??

Best regards,

Verbal
