SIP in higher education

["Shenen Shenen" <>]

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..and softphones 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      [mailto:]
serctl add 651  1234      [mailto:]

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!
