Hello, I do not remember exactly what was that presentation about, but maybe topoh module is something that can help you if you need the contact to be hidden.

I would like to create such a setup. I'm looking for pointers if there is a particular module/method that would be ideal to to use for this. Any other gotcha's to consider in such a setup. My plan is to keep the transaction on the same kamailio by not altering the VIA but allow the subsequent in-dialog transactions to potentially hit another kamailio by changing the contact to a shared SRV record (and encoding the freeswitch box's IP into it for later retrieval.) Thanks in advance.

Yes I've played with topoh but I need more than hiding, I need to store data (freeswitch's ip) in the contact header.
