May be I didn't provide sufficient details, so I'll elaborate.
I'd like Kamailio to 'talk' to only known dispatcher gateways, so in the
REQINIT route I do:
route[REQINIT] {
# Silently drop requests from unknown gateways, very strict mode
if(!ds_is_from_list()) {
xlog("L_ALERT","blocking $rm request from unknown gateway,
UA=<$ua>,
IP=$si:$sp\n");
exit;
}
Now, after dispatching a call to some carrier who's gateway address is a
FQDN that resolves into multiple IP addresses, when an in-dialog request
like BYE or re-Invite from the downstream carriers arrives,
ds_is_from_list() returns false and the request gets silently ignored as
indicated in the above route block.
Is that the expected behavior of ds_is_from_list() function?
Thanks,

Hi ppl,
The problem I'm facing is that function *ds_is_from_list* seems to return
false when a gateway's address is a FQDN that resolves into multiple IP
addresses (I'm talking about A records), consequently in-dialog requests
like BYE and re-Invites get blocked since they don't pass the
*ds_is_from_list* validation.
Am I missing some parameter or something?
Thanks,
