VOCAL SER SIPX NIST ASTERISK DYNAMICSOFT WHICH IS THE BEST FOR LARGESCALE DEPLOYMENT

Hello all,

I've been investigating a new business that involves VOIP and will
probably need to scale hopefully into the 100s of thousands of users.
I've spend the last two weeks evaluating VOCAL (which I like) and I've
just started on SER. Which leaves me with SIPX, ASTERISK and NIST-SIP
on the open source side and Dynamicsoft (who claim to be the 'gold
standard' on the commercial side. I'd like to start a thread here to
get people who have deployed each of these solutions to start talking
about the pros and cons of each. Here is the criteria I would like to
evaluate each on:

Higher numbers are better

Ease of installation: (1-5)

Quality of Documentation: (1-5)

Level of development activity1-5)

Scalablility1-5)

Standard features1-5)

Unique features1-5)

User provisioning capabilities1-5)

Availability of commercial support1-5)

Real world implementation (verifiable implemenations) (1-5)

Put most importantly, I'd like to get some realworld implementation
comments from people who are actually using these products. They all
look pretty good at the installation phase, but I'd like to hear from
people who have actually deployed to try to understand where the problem
areas.


Thanks,

PS Its kind of a shame that we cant get all these talented people to
work on a single project.

 

Hello!

support, ...)

software. Takes about 10 minutes to install the server for a person with
basic technical knowledge (you just have to answer few simple questions
like IP addresses, time zone, ...)

4.5, see it yourself, it is publicly available at
http://www.portaone.com/resources/documentation/index.html

4 - continuous development, improvements with each new release

4 - single server supports about 40-50 call attempts per second, which is
more than enough for the average size ITSP, multiple server deployment
available.

5 - all the standard features, call authorization, customer private

routes, accounting, ...

RTP proxy for NAT traversal, media server for error announcement, "Follow
