Hi,

I'm trying to implement voicemail with ser_0.8.12 and sems_0.1.0 on the same machine. All servers seem to be running alright, but when I dial a user who's voicemail option is enabled, and is offline, the xlite displays "trying" for a while and then 408 request timeout. The logs in /var/log/messages says

Error: ## Wrong FIFO Interface version ##

Any idea about this?

Configurations are as follows.
