[Serusers] SEMS Voicemail Vs SER vm module

[Koyama Zehi]

Hi Steve,
thank you very much to teach me about the relation between SEMS and SER.
I am using this version "ser_rel_0_8_12" . I have downloaded it from CVS.  Now I am very sorry to trouble you again.  I would like to ask a question about mail client, I maen to say that, i wanna to know that is inside the sems mail client is available as defaultly if yes then i have to do some setting or configuration in some specific modules of  SER or SEMS. otherwise shall I have to download some other mail client and do some specific setting for it.
 Now after starting the ser and sems on the same machine, I tryed to communicate with other softphone (i.e. also registeres with the same Ser proxy) but I am getting these messages from fSer proxy
1) Status: 100 Trying -- just wait a minute.
2)Status 404 voicemail: no email address for user.
3)Request: ACK

I am inserting my ser.cfg file, please have a look and teach me if their is something wrong...........

Koyama:

First if SEMS messages for Koyama are to be delivered to
zehi_koyama at yahoo.com then this email address must be present in the
subscriber record on the SER proxy for Koyama. The subscriber
email_address field is where SEMS looks for the destination address
to which to send email.

Next, where to run SER & SEMS. I happen to run everything on the
same machine. SER listens on port 5060, SER_VM on 5090 and SEMS
interacts with SER_VM via the fifo defined in it's configuration file.

SER_VM is an intermediary between SER and SEMS. I did this
because I want SER to use a failure_route route block to forward
unanswered calls to a specific destination. However since this destination
must be specified as a and SEMS doesn't listen on a
port I need somewhere to send the call. SER_VM does this. It is a
second instance of SER with only enough logic to handle the "voicemail"
request.

In my case this logic allows users to send a message to the SEMS
voicemail application, contact the SEMS announcement application where they
get a general University status message or contact the SEMS echo
application to perform an echo test. Most calls so far are going right
to voicemail.

I hope this helps.
