Hi there,
Questions:
- How can I setup SER to forward up to 120 calls per asterisk node
before switching to another one? does SER keep a list of open RTP connections to the box forwarded to?
No, SER does not keep the list of active connections. You can probably distribute calls to PSTN gateways in a round-robin fashion, that could give you similar results.
Alternatively, maybe you can use failure routes to handle this, if your PSTN-gateway can supply meaningful responses for you to handle.
Cheers,
