Subject: Re: [SR-Users] Load balancing traffic based on SIP URI

Hi Federico. In mi case i have to force some RURIs to a determinate Asterisk . There was some logic to do that instead letting kamailio to handle that situations

I haven't tested option 3 , but it must do what you expect i think. Maybe you would need to adjust 

 ds_hash_expire

Hi,
if I understand correctly your problem is that the first INVITE for a specific URI will go to a server and the conference will be instantiated there. Then you must route all the INVITEs from the other participants to the same server, is it right?
If this is the case why not use algorithm 3 in ds_select_ds (or ds_select_domain) which does hashing over Request-URI?

Regards,

Federico

Hello,

I want to use Kamailio to load balance traffic across multiple asterisks.
The problem is that my SIP traffic is related to conference, so if a SIP call
for a particular URI is sent to an Asterisk instance, any subsequent calls for that
SIP URI should be sent to the same Asterisk instance.
Is there anyway to achieve this in Kamailio?

Thanks,
Nitesh
