Hi all, I have been reading the archives for the ser mailing list, as well as looking round the voip-info.org site, and cant really find an answer to my question... We are using ser as a sip proxy + registrar to the subscribers database (mysql). At the moment it is doing a fine job routing calls between sip users on the same server + accepting calls from pstn network into the server (setting up aliases of numbers to users). I have tried using sems, and I can get it to work - however its more limited than asterisk in terms of functionality (like being able to call in for voicemail, rather than just emailing them..) If I set up a rule to forward to an asterisk server (running on same server, different port) - how can I handle the auth / setup of the mailbox for them? Ie. They have already registered on the ser box, so is it possible to link asterisk in, so that the same username / password is used if people call in to the voicemail admin to retrieve voicemails? Or, do we have to create the users twice, once in ser and once in asterisk? Let me know if I have got the wrong end of the stick (or if I have phrased it badly!!) Cheers, Bill.
