Simply modify your dialplan to do this:
Exten => s,1,dial(SIP/${ARG1}@SIP1&SIP/${ARG1}@SIP2..)
If you are using a "cookbook" dialplan, it's probably a 4 or 5 line change.

Subject: [asterisk-users] Combining multiple SIP providers
Hi
What is the best way to combine multiple SIP providers to achieve
1) Higher concurrency (for eg. 2 providers with 50 concurrent calling limits
could be combined to give a limit of 100)
2) Redundancy (use another if one is down)
I have a feeling that this will need some SIP Proxy like OpenSIPS but what
could be the architecture ?
Much thanks!
regards,
Anita
