The random value is based on the Call-ID, use debug=4 and add an XLOG as
follows before every call to cr_route:
xlog("L_ERR", "call-id for this call $ci");
Check the call-id is different every time and the CRC32 algorithm to
calculate the hash values gives a different answer.

When restarting kamailio I found out that it reads
both routes
Jul 30 11:46:40 [9165] INFO:carrierroute:rule_fixup_recursor: hashless rule
with host Y.Y.Y.Y hash hash_index 1
Jul 30 11:46:40 [9165] INFO:carrierroute:rule_fixup_recursor: hashless rule

I jjst do not know why it's not reading the prob

Dear Sir,
Please find below carrierroute table...

on kamailio.conf:
if(!cr_route("default", "0", "$rU", "$rU",
"call_id")){
sl_send_reply("403", "Not allowed");
} else {
# In cas of failure, re-route the request
t_on_failure("1");
# Relay the request to the gateway
t_relay();
}
When trying to call 00123456666 the call is forwarded all the time to
X.X.X.X IP and never to Y.Y.Y.Y IP...why this happening? It's like Kamailio
is not reading prob field

I'm really not sure how it works when you use
a 0 prob.
Try something like 50/50 and check if the requests go to both servers.
Also, some extract from /var/log/messages will help.

Dear Sir,
My tables are defined as below:
*carrierroute table:*
id carrier domain scan_prefix flags mask prob
strip rewrite_host
19 5 1 00 0
0 0 0 IP_address1
19 5 1 00 0
0 1 0 IP_Address1
*route_tree table:*
id carrier
5 default
*In kamalio.cfg:*
if(!cr_route("default", "1", "$rU", "$rU",
"call_id")){
The issue is that kamailio is forwarding all calls to IP_Address1 and
never to IP_Address2 even if prob is 1 for IP_Address2 and 0 for IP_Address1
Any help please?
