There was added sipgrep utility written by Alexandr Dubovikov shurik@start4.info into SER's source tree (utils/sipgrep).

It is a wrapper on ngrep which * filters SIP messages according number in To or From header fields * displays From tag, To tag, Call-ID and branch in different colours, thus it is possible to trace dialogs or transactions by "one look into message" ... this is really great! ;-) * It can store received messages into a file and show them (together)

For a bit more info see README. For other info contact author.
