Hi List,
I have freeswitch on a server with a sangoma A104D card and ss7 lib, with 4 E1 links. All links carry ss7 signalling information and are grouped in 2 linksets.
I would like to add some redundancy or failover with a 2nd identical server so that if the first one fails, I can do some kind of ’sofia recover’ and retrieve all ongoing calls. Or at least, reduce the downtime to a few seconds.
I cannot just put each linkset on a separate server as the signalling information for a given call may arrive on any link set. For example, I can receive the call setup on a linkset and the release on another.
Also, I cannot have 2 point codes with my telco, unfortunately.
What do you guys use to solve this problem? Is there a way to forward a ss7 signalling message to another freeswitch or to have a passive listening mode one the backup server (with some kind of switch duplicating the E1 signal on both servers, or just Y cables...)?
Thank you!
