Also, I tried setting the Contact header in onsend_route, but it seems that it's overwritten after that. Perhaps I need to modify it on the second Kamailio server? Is it possible to change it before it's sent on the first server?

Hey all,

I have 2 Kamailio systems replicating REGISTER's to each other. However, I've noticed that the Contact header seems to be wrong on the second server.

For example, if I have endpoint 1.1.1.1 registering to 2.2.2.2, then 2.2.2.2 is calling t_replicate() to 3.3.3.3, the Contact header once it is received on 3.3.3.3 is user@2.2.2.2. I think it should be user@1.1.1.1.

Where's the best place to change this before it is sent?
