Hi list,
We have a setup with 2 redundant stateful SER SIP-Servers with accounting.
For calls to the PSTN we have 2 ISDN-PRI gateways connected to different ISDN-PRI lines.
We need to implement a dynamic failover mechanism and load balancing.
a) Incoming calls: No problem, the PSTN switch takes care of that b) Outgoing calls: Both GWs are registered at both SERs; calls are usually relayed with "t_relay_to_udp(x.x.x.x, "5060");" But how can I implement a quick failover including load-distribution between those gatways? I.e. if I receive "busy here" or no response after a short period after the "invite", the call should be redirected to the other GW.
Thanks in advance for your help!
Best regards, Gerhard
