[Serusers] SEMS/SER Wrong FIFO Interface version

[lakmal at lankacom.net]

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.

voicemail.cfg
