New subject: [Serusers] ser.cfg for VRRP protocol => using t_replicate for 2 proxies

15 Jun 2006


      Hi!I've 2 asterisk at home and I use openser becouse I want use more proxies
for my softphones;my problem is this:
I'm using vrrp protocol;
192.168.25.1 is the master   (asterisk1)
192.168.25.2 is the slave      (asterisk2)
192.168.25.200 is the virtual IP.
then I have my softphones on a Xp pc with IP 192.168.25.10
I set my softphones with 192.168.25.200 and they run, only that, the problem
with asterisk is that softphones and IP phones(some like wi-fi) can register
only one proxy, and asterisk can't make a option for more proxies than
one;so the proxy is the 192.168.25.200, but at real it is
192.168.25.1..andsoftphones or wi-fi are registered only in the first
asterisk with the
192.168.25.1..if the master falls down the slave hasn't the authentication
SIP registration...only the master..So I must use openser or ser to have 2 =
box
my problem is resolved only if I use the redirect option to have 2 =
asterisk box so the database can be opened and read from one asterisk to the
other;if the master falls down the slave has all the configuration and the
SIP registration, so it can work without problems.
A) I've set this file on asterisk 192.168.25.1 the master

Must I call this file ser.cfg?Right?Must I set the
on the master
listen=192.168.25.1  #on the master
port=5060
on the slave
listen=192.168.25.2  #on the slave
port=5060
Then I use on all the 2 linux;
#chkconfig -add ser
#chkconfig -add mediaproxy
And ser and mediaproxy works like deamon every time I start-up the 2 linux.
Is it right to add this 2 sip number in openser or ser in this way?(they're
registered in asterisk and 650 is a number from a X-lite, 651 from Phoner)
serctl add 650  1234      650@192.168.25.200 [mailto: 650@192.168.25.200]
serctl add 651  1234      651@192.168.25.200 [mailto: 651@192.168.25.200]
Is it right this configuration?If the master falls down the slave has all
the Sip registration authentificated and run without any problem?
100000 thanks!
