[asterisk-users] Combining multiple SIP providers

[Danny Nicholas]

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.

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
