Hello fellow developers,
I am getting ready to implement my own SMSC, connecting to Osmocom CN
via GSUP (see OS#6135), and I have a question about SMSC address
terminology.
In traditional commercial GSM networks, the SMSC address visible to
the user (prepended to the TPDU for MT SMs, stored in EF_SMSP record
on the SIM for MO SMs) looks like a phone number in full international
format, with TON=1 and NPI=1. For example, T-Mobile's SMSC address is
+12063130004 (to an uninitiated eye it looks exactly like a regular
phone number in Seattle, WA), while the SMSC of Mexican Telcel is
+5294100001410 - one digit longer than regular phone numbers in Mexico,
and a little irregular in structure.
What is the correct term for these SC-address phone-number-thingies?
Are they Global Titles - or is GT something different?
If I were to make up fake global-looking SMSC addresses of this form,
e.g., something like +1xxx55501xx for NANP territory, would it be
correct to call such SC-address a fake Global Title?
Just wondering...

Dear list,
I managed to set up my E1 based Nokia BTS, the complete Osmo-CNI
stack, SIP-connector and Asterisk. MO/MT calls do work as well as
external SIP calls to and from mobile as well. But no matter what I do
only plain FullRate calls are possible.
Under osmo-bsc.conf code support is set like this (the BTS HW do
support all of these codecs):
codec-support fr efr amr
but once I also add "codec-list fr3 fr2 fr1" to the MSC section of the
osmo-bsc.conf, the calls wont establish anymore.
I watched Neel's OsmoDevCall presentation on this topic, but it is not
very clear what codecs are supported when osmo-sip-connector and an
external PBX is used?

I have git-cloned https://gitea.osmocom.org/cellular-infrastructure/osmo-bts this project in order to have a solution for calling 2 mobile phones in my own network. I dont have any experience with this. I have instaled and configured in the past the same solution from PenHerts git but it is a lil bit old. I want to configure and install this solution bu i do not know the exact steps to do that. I dont find any configuration file or i do not know what to do with them. I do not have any experince with this domain and i want to know the steps in order to run this project properly. Could you help me with any directions?
