append_branch() overwrites next hop of main branch (Re: Re: How to append_branch() after location lookup without affecting looked up branches?)

Hi

I got it almost working but I am hitting the next issue:

After t_load_contacts() I have branches from registered locations.
Those contain a destination uri from the path header.

       append_branch();
       $(branch(dst_uri)[-1]) = "sip:host.example:5060";
       $(branch(uri)[-1]) = "sip:[email protected]";
       t_on_branch("BR_TO_PBX");
       route(RELAY);

branch_route[BR_TO_PBX]
{
	xlog("L_INFO", "$cfg(route): DEBUG: RUID: $ruid RURI: $ru Next Hop: $nh(u)\n");

	if ($ruid == $null) {
		append_hf("Diversion: <$fu>;reason=simuring\r\n");
	}
}

In my case, I load one contact from registered locations and add
[email protected] as another contact which shall ring simultaneously
(the external mobile phone associated to the user).

After append_branch() and setting the branch uri and dst_uri of the
appended branch, the call is correctly routed to the [email protected]
but branch 0 loaded with t_load_contacts has lost it's destination URI,
$nh(u) is empty so it is not sent via the SBC through which the
registration happened and which is documented via path header.

Any idea why this happens and how I can preserve the nexthop?

Mit freundlichen Grüssen
