Hello,

have you changed the value for the force_dst modparam for dispatcher module?

  * https://www.kamailio.org/docs/modules/stable/modules/dispatcher.html#dispatcher.p.force_dst

Also not, iirc, in the older versions the value was 0.

Cheers,
Daniel

Hi

I am using the dispatcher module with Kamailio as a front-end Registrar/LB in front of a cluster of Asterisk boxes. I have come across an issue with SUBSCRIBE messages not getting routed to the correct server in the event that the phone endpoint's dispatch set is changed. It will still go to the old server until such time as the phone is rebooted.

The reason this is happening is because the 200 OK in the response from the Asterisk server has Contact set to its own IP:port and subsequent in-dialog reSUBSCRIBE are sent with the original Asterisk ip:port in the RURI. When Kamailio receives these reSUBSCRIBE it does not change the RURI even though ds_select_dst is being called in the [WITHIN_DIALOG] route.

My feeling is I have two choices - either alter the Contact in the reply from Asterisk, or, change the RURI manually on receipt of an in-dialog SUBSCRIBE.

Has anyone else come across this, or have advice on the best way to handle this?

Thanks
