Hello,

you are confusing what are Contact header parameters and Contact URI parameters.

If you want to be preserved in location and used later in R-URI, you have to give it as Contact URI parameter (like transport), but some_id is given as Contact header parameter.

Cheers,
Daniel

I don't think the specifics matter that much, but the general idea of preserving the Contact URI parameter for subsequent messages is reasonable and I've seen it work like that with other non-Kamailio registrars.

I wonder if this also happens without fix_nated_register before save().

Any specific reason to insert that parameter in the contact as opposed to just adding a custom header?

Hello!

On REGISTER I have a Contact header like
Contact:  <sip:90002@192.168.0.26:48579;transport=TLS>;some_id=90002-21080
But on calling fix_nated_register() -> save(), param some_id is lost from info, so, on INVITE to this account, some_id not appears in RURI.
Is this a bug or a feature and I do need to find some workaround?
