Two Asterisk boxes, only ONE signal link

Hello

It is possible to have Asterisk_1 forward SS7 signalling for
Asterisk_2. 
Chan_ss7 has a cluster feature where multiple hosts
supervises each other. 
The chan_ss7 source comes with an example configuration in
the file 
ss7.conf.template.two-hosts.. For your setup, if l2 is
connected to 
Asterisk_2, and host Asterisk_2 has the network interface
if-1, the cluster 
section should be something like

[cluster]
; Listen on TCP port 5040
port => 5040
; Signalling traffic for link l2 is monitored by host
Asterisk_1 on interface 
if-1
l2 => Asterisk_1#if-1

Hello Seba

It will work with one point code shared between two hosts
and one signalling 
link connected to one host, provided the hosts are
interconnected through a 
LAN.

Do you think that it

HI SEB

YOU'RE RIGHT, THERE IS A BUG IN CHAN_SS7. IN YOUR SETUP,
ASTERISK_1 MUST 
BELIEVE THAT ASTERISK_2 HAS A SIGNALLING CHANNEL, OTHEWISE
IT WILL NOT ALLOW 
CLUSTER CONNECTIONS.

THE PROBLEM WHERE A SIP PHONE REGISTRATION IS ON ONE
ASTERISK BOX, WHILE A 
CALL IS INITIATED TO THE SIP PHONE FROM ANOTHER ASTERISK BOX
CAN BE SOLVED BY 
SHARING A DATABASE BETWEEN THE ASTERISK BOXES THAT KEEP THE
SIP REGISTRATION 
INFORMATION. THIS MUST BE SETUP IN THE EXTCONFIG.CONF
CONFIGURATION FILE 
WHERE YOU SPECIFY THE DATABASE ENGINE, THE DATABASE NAME,
AND THE TABLE NAME 
(E.G. SIPUSERS, SIPPEERS) CONTAINING THE SIP REGISTRATION
DATA. IN ADDITION, 
YOU ALSO NEED TO SETUP THE DBMS.
