Title: No Speech recognition if 1 NSS machine (Speech server) is down.
Post by: C_Genesys on February 06, 2017, 11:12:51 AM

We have two NSS server and both are configured as primary for load balancing

If 1 NSS machine is unreachable the MRCPPROXY does detect it (as seen in logfiles) but still tries to use that NSS server. This is not the expected behavior ! Even worse it doesn't even try to access all other NSS servers.

Which Results into no speech recognition at all,  as a result. DTMF is used.

This happens only if the machine is down or not accessible over the network (port is stealth).

Any pointers what  could be the issue ?

Below are some part of MRCPPROXY Logs.

Did you add connection to the second NSS from MCRPProxy object?
