I do it (update the $ur with the right destination IP) for all calls (INVITEs).
If a SIP client registered on Kamailio1 calls a client registered on Kamailio2
then it functions. If an other client calls through an Asterisk (which is
registered on Kamailio) then it doesn't function! Kamailio1 doesn't forward
INVITE to Kamailio2, Asterisk gets 'Busy'!Please see my test cases bellow: 3 of
them function, 1 of them doesn't function!
Asterisk obviously doesn't send some part of the INVITE message which is needed
to call another Kamailio.
Can you give me some advise how to solve it? Which other variable should be set
to relay the INVITE to the 2nd Kamailio?
Thank youRegardsMarko

Hi all,
I have here: Kamailio 1: 192.168.0.11 Kamailio 2: 192.168.0.21 Asterisk 1:
192.168.0.12
Asterisk1 is registered on Kamailio1 as User 100. Asterisk1 shouldn't be
registered on Kamailio2.
User 111 registered on Kamailio1 User 211 registered on Kamailio2 User 121
registered on Asterisk1
Test cases: --------------------- 111 calls 211 - OK 211 calls 111 - OK 121
calls 111 - OK 121 calls 211 - Kamailio1 doesn't forward INVITE to Kamailio2,
Asterisk gets 'Busy' !?
Is the approach just to replace destination IP-address in $ru, depending from
1st digit, right?
yes, if you partitioned the users and you know by first digit where it should
be registered, then all is fine -- update the r-uri and then you can relay to
the other server.
Cheers,
Daniel
If not, what is the right approach to reach the remote users from Asterisk,
which are registered on remote Kamailio and not on the local Kamailio?
Thank you Regards Marko
My changes in kamailio.cfg in both kamailios (based on kamailio-basic.cfg) :
--------------------------------------------------------------------------------------------------------------
kamailio1.bindip = "192.168.0.11"
kamailio2.bindip = "192.168.0.21"
... route {
if (is_method("INVITE")) {
if($rU=~"^1[0-9][0-9]$") {
$ru = "sip:" + $rU + "@" + $sel(cfg_get.kamailio1.bindip) +
":5060";
}
else if($rU=~"^2[0-9][0-9]$") {
$ru = "sip:" + $rU + "@" + $sel(cfg_get.kamailio2.bindip) +
":5060";
} }
...
sip.conf in Asterisk1: ----------------------------------
register => 100:[email protected]:5060/100
[100]
type=friend
host=192.168.0.11
secret=abc
context=kamailio
[121]
type=friend
secret=abc
host=dynamic
context=kamailio
extensions.conf ------------------------------- [kamailio]
exten => _[1-4]XX,1,Dial(SIP/100/${EXTEN},30)
exten => _[1-4]XX,n,Hangup()
