[Freeswitch-users] HA and conference events

[Mike Kane]

Hello all.  Quick  question.  We successfully configured db functionality
using Postgres to support HA, which is working quite well.  The one anomaly
we see is that when in a conference and the originator would like to add a
member, originator sends a "Refer" to Fs conference server.  That triggers
FS conf to generate "Notify's" that are sent just after the "Refer" with a
sipfrag 100/Trying and it's sipfrag 200/Ok response.  This functionality
works with sqlite, but not with Postgres.  Any ideas on what we maybe
missing?  Below describes the messages flow.

Member A joins FS conference
Member A would like member B to join so member A sends a "Refer" to FS
conference server requesting conference server to invite member B.
FS conference server sends invite to member B
FS conference server sends member A a "Notify" with sipfrag 100/Trying
(this does not happen now)
FS conference server sends member B and invite per the "Refer" sent to it
(normal call flow for member B continues as he/she joins)
FS conference server sends member A a "Notify" with sipfrag 200/Ok (this
does not happen)
