Hi Manoj The UAC must increase the CSeq value by 1 in the Register request with credentials.

Call flow is as follows UAC UAS/Proxy |-------F1 (REGISTER)------------------------------------------> | |<-----F2 (407 With proxy-authenticate)--------------------- | |-------F3 (REGISTER with proxy-autorization)-----------> | |<-----F4 (200 OK)------------------------------------------------>| Must the UAC use the same CSeq value throughout the complete registration process? (That is both F1 and F3 have the same CSeq) Or Can the UAC increase the CSeq by one in F3 ?( That is, if CSeq of F1 is 1 and CSeq of F3 is 2) Cheers!
