Hello All,
First, I created subtle problems in SER by having an alias entry for the host ip in the
ser.cfg file.
I don't recommend doing the following [where 10.10.10.49 is the ip of the host where
SER is running].
alias=10.10.10.49
Next, I've had similar problems to a user who posted recently about SEMS being
unstable. Occassionally it just stops playing the greeting, however, even if the greeting
doesn't play, SEMS will still record audio. Overall, I've had a lot of frustration
with SEMS.
Attached is my ser.cfg file and some error messages from syslog.
Here is a scenario which is causing problems with voicemail.
------------------------
User sip:info@mydomain.com is not logged in anywhere, however that user has calls being
forwarded to sip:mvestal@mydomain.com and sip:esavelle@mydomain.com.
The location table shows these entries correctly. In addition, mvestal and esavelle are
also in the location table at specific ip addresses.
When a call come in for sip:info@mydomain.com, it gets forked propery. However, if no one
answers the call before the fr_inv_timer expires, SER tries to hand the call off to VMSER
[second instance of SER which is running on port 5090 and is handling voicemail] but the
error messages in the attached logs show up. The calling party typically hears ringing
continue after SER had timed out, and then gets a busy tone a few seconds later.
I'm also going to try Asterisk. There is a specific feature of Asterisk which I think
would benefit SER/SEMS a lot.
We will set up Asterisk so that we do and append_branch(); in SER as soon as a call is
initiated to an internal extension. Asterisk can then be set to wait a certain amount of
time before it answers the call. This way, the fr_inv_time feature of SER isn't
necessary for getting calls into voicemail [SEMS or Asterisk.]
Also, it is very nice to be able to use a phone to check voicemail. No all users are
necessarily sitting on their email inboxes all day long.
Any help on the bug would be greatly appreciated.
