[asterisk-ss7] Two Asterisk boxes, only ONE signal link

[seb]

Hi Anders,

sadly it didn't work... I've used the configuration sugested with both
Asterisk_1 and Asterisk_2 sharing the same OPC. Asterisk_2 (the one without
signaling channel) is not able to connect to Asterisk_1 (that one with
signaling channel), in fact Asterisk_1 fails to bring up the cluster. The
workaround was to change the ss7.conf on Asterisk_1 (only on Asterisk_1)
saying that Asterisk_2 has a signaling channel (even if it is not true) and
adding one line to the [cluster] section:

l1 => Asterisk_2·if-1 ; <<<<-------------  I added it !!!

only in this way I've got the cluster work... the problem is that it doesn't
work properly ! : the IP phones registered in TELCO can make calls only to
the IP phones registered to the same Asterisk where the last call was coming
from... so if for example you make a call from Asterisk_1 to TELCO then
TELCO wont be able to call Asterisk_2 even if it will be able to call
Asterisk_1....

Any ideas ?

cheers,
