    Hi Friends,

    If possible can I get a count of bytes for following calls.

    1.SIP to SIP Cliet Call.
    2.SIP Client to PSTN Call.

    Regards

    Dear, Michael!
    I was facing with following assumptions:
    typical SIP INVITE – about 1375 bytes (without UDP (or TCP) and IP overhead) and about 1400 bytes including UDP (or TCP) and IP overhead.
    typical SIP 200 OK – about 800 bytes including UDP (or TCP) and IP overhead.
    typical SIP 100 Trying and SIP ACK – about 300 bytes including UDP (or TCP) and IP overhead.
    Examples of call scenarios 1 and 2 you may find out in IMS 3GPP or TISPAN specifications.
