I have a pair of asa5520 configured as active/standby failover pair.
I have a requirement to carry UDP video conferencing sessions through my firewall.
During testing I made a video call from a unit on the inside to the outside. The call establishes fine.
I then Fail and interface on the active/Primary unit, the standby becomes active and the remains up (image freezes for 5 secs, which is fine).
If I reconnect the interface on the primary, wait a minute or two and fail an interface on the active/Secondary unit, the call freezes for 5 secs and then resumes.
After approx 60 secs running on the active/Primary the call drops?
I this right?
The video call is a standard H323 call using Tanberg units.
