Hey all,
 
Another wierdness for a sunny tuesday afternoon....  Have been using ser and * quite successfully so far, and am not into the stage of testing voicemail.  Currently I am using * with mysql vm storage.  I have a failure route which affter the fr_timer expires, does:
 
 
failure_route[4]  {
	# If we've got here, it means that a call timer has expired, and the user is in the
	# voicemail group. Therefore we're going to try and hand off the call to the Asterisk
	# voicemail system.
        revert_uri();
     	rewritehostport("asterisk.dev.inmarsat.com:5060");
        log (1, "VOICEMAIL: VM-Divert --> Handing off to Asterisk\n");
     	append_branch();
	append_urihf("CC-Diversion: ", "\r\n");
        t_relay();
	break;
}
 
This works great for normal users who are registered but not answering their phone (or indeed are busy it seems - i havent' worked out how to configure this behaviour -- any suggestions?).
 
However, i have two problems:
 
(1) If the call is from Nonnat  UA --> SER --> Mediaproxy --> Nat UA
                                                      |
                                                     \/
                                               Asterisk VM
 
then the Nonnat UA doesn't get audio from asterisk vm. I think this has somethign to do with mediaproxy trying to proxy the vm request when it shouldnt and not knwoing where to send it - again, any suggestions?
 
(2) The most annoying issue at the moment is for offline users.  It seems logical that if you have an offline user (one that has been found in the subscriber db but just isnt' registered at the moment) you might want their address to divert to vm.  However, no amount of fiddling has enabled be to use a failure route for this, and i'm not sure why.  In desperation i just created a new route block to handle it - the same as above, but called route[4] instead of failure_route.  This at least forwards the request correctly. However, all i get is "The p...." and then the media stream cuts out, and * console shows the channel has been hung up.  Below is the ngrep.  For some reason two INVITE reuqests are sent  from ser(.136) to *(.137) and i'm not sure why.  Notice also that a CANCEL is generated, which corresponds to the media stream dying almost as soon as it starts, but again i'm not sure why....
 
If anyone has anyideas... if you need to look at the ser.cfg then let me know. I'm sure there must be a mor elegant way of handling vm but im not sure what it is at the moment!
