I do this with running a pflogd instance; unlike tcpdump,
pflogd is well suited to have its logs rotated and behave accordingly.
For example,
$ grep sip /etc/rc.local
/sbin/pflogd -s 65000 -i pflog1 -f /var/log/siplog
$ grep sip /etc/newsyslog.conf
/var/log/siplog 600 3650 * @T00 ZB "pkill -HUP -u root -U root -t - -x pflogd"
after pflog1 has been set up to capture certain traffic, as in
pass log (all, to pflog1) on $phones
