I came across this while browsing through the coverity defects.

gboolean first = TRUE; is never changed

Does the following change make sense to those who are familiar with SIP?

diff --git a/epan/dissectors/packet-sip.c b/epan/dissectors/packet-sip.c

                        break;  /* need more data */
                offset += len;
+               first = FALSE;
        }
        return TRUE;



Hi Martin,
I'm not really familiar with SIP over TCP (in all my use cases, SIP is over
UDP) but your proposal makes sense.

Best regards,
Pascal.
