SBC HA pair and berpd force switchover during active call

in Acme Packet (MOSC) 1 commentAnswered ✓

Customer is running AP3900 HA pair and using TLS/SRTP to encrypt trunks.

It was observed that if active/standby switchover is forced during an active call, RTP remains operational, but SIP signalling is broken.

This is indicated by fact that if we force switchover by notify berpd force and then hang up on local side, remote side does not receive the BYE message, instead we get "SIP/2.0 481 Call leg/Transaction does not exist"

If we do not force HA switchover, then BYE is sent and received normally.


Can anyone confirm this to be "normal" in case of TLS/SRTP trunks or do we investigate the issue further?

Howdy, Stranger!
