Hello all,

Recently I've been looking to try to get the SMPP functionality of the Osmocom network working. According to this page about port numbers

https://osmocom.org/projects/cellular-infrastructure/wiki/Port_Numbers

the port to send packets to for SMMP is 2775. However, when I tried to do this, the connection was refused. I assumed I had to enable it in the VTY, but when I went into the MSC's VTY, the smpp-config node was not present like the manual states:

https://ftp.osmocom.org/docs/latest/osmomsc-vty-reference.pdf (page 128)

I also want to view/change the SMSC's address because this is needed to create a packet with the correct application header, as far as I know. To do that, I also need to be able to access the smpp-config node (see picture).

Is the manual outdated with the smpp-config node being removed, or am I missing something? I'm going to keep reading up on the manuals but I figured I'd ask here to see if the manual is indeed outdated or if there's another way to access smpp-config.

Thanks for reading.
