Yes there is a race condition that is possible. Sipxbridge has an algorithm that handles the race condition which essentially allows the phone to win if there is a clash. If the phone initiates a MOH renegotiation (or indeed the called party picks up ) in 500 ms. then sipxbridge will not talk to the park server to initiate the MOH. On the other hand if sipxbridge does not see signaling that indicates that the phone has initiated the MOH within that 500 ms, then it will initiate the MOH INVITE. This has been quite tricky to get working correctly so you are not advised to turn MOH on the phone AND on sipXbridge ON at the same time ( it is not a supported configuration - I fixed a bug just yesterday in that connection). However, it *should* work even if both are enabled simultaneously. If you are running an experimental installation, please test the configuration and report back any problems. Thanks Ranga -- M.
