Currently ACE is not SIP aware.
ACE will support SIP with version 2.0. It will support SIP load-balancing over TCP and UDP, it can load-balance based upon the SIP header i.e. can load balance based upon the Call-ID (even though information for many calls are in the same TCP connection). It
can also do stickiness based upon Call-ID.
Additionally, ACE 2.0 supports SIP probes.
Currently you can only use udp probes
probe UDP5060 udp
interval 1
faildetect 2
passdetect interval 60
passdetect count 2
port 5060
!
probe ICMP icmp
interval 1
faildetect 2
passdetect interval 60
passdetect count 2
!
