Hi ram,

Part of the solution I built is a redundant openser in front of a redundant freeswitch install.
FS acting like an SBC ( ie, all calls comes through, and are filtered based on xml_curl dialplan rules ).

Asterisk was not the solution for me, as it's not as easy as FS to scale and manage in my HA environnement.

I'm currently thinking of adding some kind of failover method in FS, to provide 99.9999% uptime even if one box fails.
The better way I saw atm, was to send to a spare FS instance everything going on the production box, allowing it to
take over the prod'box in case of failure ( ie taking the ip, opening rtp ports that were opened, and keeping tracks of SIP transactions
and their status ).
I believe this sort of features cannot be implemented easily in asterisk, but in FS it should not be too much difficult. Maybe adding a new channel state tracking changes on the master it's spare of... ( why not building also a master/master cluster ? ) ....

If you need more, just ask,

Hi

thats really nice

is this what your build system looks my imagination

Openser-----freeswitch boxs (3 or 4) ----PSTN or VoIP Provider

Quite this kind of setup, a little bit more complicated, as I have a few media servers, and other things on my voip cloud...

To simplify, I have more something like that ( even it's not quite accurate ):

External UA's ---> FS --> Oser --> FS --> PSTN.
||
Internal UA's

If yes

I have couple of questions

1. Is the user register with Openser or Freeswitch

Openser for internal users, fs for externals.

Openser is really better if you intend to have a lot of UA's registered.

2. are you using Dispatcher or LCR Module to send calls to Freeswitch

dispatcher and dns.

3. how are you able to manage PBX features

PBX features are managed in fs with prefix added to numbers for features (for example: interception is int{thenumbertointercept} ).

4. CDR done in Openser or Freeswitch

both to provide redundancy of information.

5. how about pre-paid and NAT handling ?

nat is handled by FS using different profiles, I don't want to deal with real NAT situations ( although I had with Oser and mediaproxy )
I don't have prepaid applications, we're a call center telco provider, but you can handle these with Oser Or freeswitch, look at mod_python or mod_lua :)

If you could share some config files offline should be good

just a set of sofia profiles for freeswitch and a good routing config for OSER should do the trick, there's nothing complicated, contact me on irc if you need :)

iam looking the same system to deploy

If you want to discuss this, you can find me on irc ( gled ).

thanks

Ram
