[asterisk-users] SER/OpenSER as registrar to Asterisk (1500 SIP users)

What about:

1) Message waiting notifications? Especially in a distributed system
with multiple Asterisk servers?

2) Different codecs for different SIP users/accounts? DTMF modes? I
know SER doesn't deal with the media at all, but if you let SER handle
registrations and authentication, then I'd rather not keep track of
codecs/DTMF on asterisk as well.

Those two have been bugging me most.
