The code below demonstrates how to access underlying range iterator by transformed iterator:
struct A
{
int x;
};
struct B
{
A* a;
};
std::vector<B> v;
int main()
{
auto a_range = v | std::views::transform(std::mem_fn(&B::a));
auto i = std::ranges::find(a_range, 5, std::mem_fn(&A::x));
A* a = *i;
B& b = *(i.base());
}
ROWID is of alias of an integer primary key:
CREATE TABLE test1(id INTEGER, b TEXT, PRIMARY KEY(id))
INSERT INTO test1 (id, b) VALUES (5, 'five');
INSERT INTO test1 (id, b) VALUES (6, 'six');
INSERT INTO test1 (b) VALUES ('seven');
SELECT rowid, * FROM test1;

Clients A and B are in Windows Sandboxes behind a router in a local network.

Add the following class to your style.css:
.scrollable-log {
overflow-y: scroll;
font-family: Monaco, "Consolas", "Bitstream Vera Sans Mono", "Courier New", Courier, monospace !important;
font-weight: normal !important;
font-style: normal !important;
font-size: 1em !important;
max-height: 400px;
}
Client C successfully call client A, but a call in the reverse direction fails. Client B successfully calls client A. See my previous post for my Asterisk configuration and clients.
IP address of client C is 176.15.165.103 and external IP address of client A is 91.122.37.167. Server IP address is 172.236.29.157.
172.28.33.149 is the local IP address of client A in Windows Sandbox (which external IP address is 91.122.37.167):

I have two clients in Sandboxes on Windows 10 machines in a local network behind a router. First client is Linphone (client A) and second client is ZoiPer (client B), so the clients A and B are behind NAT. Also I have Linphone (client C), ZipPer (client D) and PortSIP (client F) on my Android mobile phone connected to the internet over 4G (so there is no NAT). The server is in the Docker container with default network configuration with all the ports mapped to the host.
My Asterisk configuration:
rtp.conf:
[general]
rtpstart=10000
rtpend=10099
