[Freeswitch-users] FS HA

Wed Jan 26 13:53:59 MSK 2011

hello Anthony,

ya, i was afraid of that... this means moving all my modules & patches to
the latest git...

radius cdr interface
odbc cdr interface

within mod_xml_cdr <= i can share this as a patch... if you are interested.

mod_say_hr - really bad programming .. needs big re-factoring but lack of
time :(
patches for mod_say_de & mod_say_fr - because wrong playing in some
scenarios

and some small stuff i made within mod_commands... anyhow this was on the
road.

anyhow i was really into understanding the way the call context replication
works... this may be the DB connection issue as the ODBC connection is reset
on switchover (im switching entire resource .. floating IP, & database)

so what really happens is the FS on 2nd node just getting sessions from
sip_recovery

from sofia_glue_recover: i see you are selecting sip_recovery table.

select * from sip_recovery;
   runtime_uuid profile_name hostname uuid metadata
24f77a1f-f315-4beb-904f-f779e8767c75 internal cxss01
102b2c7f-466f-4b6d-a795-e2cc25630e78    24f77a1f-f315-4beb-904f-f779e8767c75
external cxss01 52834d99-c1be-4832-bee9-7ba05238871d

so, what do you do afterward?

on the recovering node i see some portion of dialplan is executed and
re-INVITEs being sent ... where do you get the DSP info for the recovering
re-INVITE ?

thanks for your help,
Tihomir.
