[Asterisk-Users] SIP Server

[Danny N]

Hello:

I am doing research on designing an architecture for a residential-based 
VoIP service.
Meaning, the platform should ideally able to handle lots of SIP sessions at
the same time. I understand Asterisk do come with SIP Proxy and Outbound 
Proxy, but
it is not scalable...and I heard about SER is a better choice. And what 
database
would you recommend. is MySQL robust and scalable enough?

I appreciate any comments.

Thanks,
Danny
