[Serusers] Asterisk "clustering" with a SER proxy?

[William Towfiq]

Hi Roy,
This is definitely possible to do with SER but not trivial because of 
the HA requirements. If you would like to discuss the solution in detail 
you can call me at +1-760-282-2222. This telephone number is currently 
forwarding to my cell phone in Rio de Janeiro. I'll be here until the 
end of this week helping a startup VoIP company with their architectural 
design but I can begin working with you early next week if you'd like. I 
am an expert in the SIP Protocol, and as you've probably noticed from 
the security audit's I've done on Asterisk or my name on 
bugs.digium.com, I'm also a Bug Marshall on the Asterisk Project. I have 
a flat-rate of $340 USD/hour for all my clients, which many people have 
seen to be more cost effective than hiring some other '$100/hr' 
consultants given the time of implementation for projects and my 
expertise in this field. I hope to hear from you soon.
