When receiving SMSCB_E_CBSP_DELETE_(N)ACK, smscb_message_fsm will iterate
over all peers to find out if some of them has still not ended, and in
that case delay sending an HTTP result.
However, the peer was sending the signal before moving to DELETED state,
and hence smscb_message_fsm would never send the HTTP result until T3
(T_WAIT_DELETE_ACK) would time out after it:

osmo-cbc - Osmocom Cell Broadcast Centre
This repository contains a C-language implementation of a minimal 3GPP Cell Broadcast Centre (CBC). It is part of the Osmocom Open Source Mobile Communications project.
A Cell Broadcast Centre is the central network element of a cellular network for distribution of Cell Broadcast and Emergency messages.
This code implements
- the CBSP protocol on the CBC-BSC interface
- a custom HTTP/REST based interface for external users to create/delete CBS messages
We plan to add support for the following features in the future:
- the SABP protocol on the CBC-RNC (or CBC-HNBGW) interface for UMTS support
- the SBcAP protocol on the CBC-MME interface for LTE support
