Hi Vallimamod, maybe some product like the beronet.com failover-switch for PRI maybe a solution. http://www.beronet.com/product/failover-switch/#2 2014-01-31 19:15 GMT+01:00 Vallimamod Abdullah < vallimamod.abdullah@imtelecom.fr>:
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! - Vallimamod .
