Hello Jenkins Builder, neels, laforge, fixeria, pespin,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/osmo-bsc-nat/+/27712
to look at the new patch set (#6).
Change subject: Add subscr_conn_fsm
......................................................................
Add subscr_conn_fsm
Insert the BSCNAT's MGW into phone calls by replacing the AoIP
transport layer address IE inside BSSMAP Assignment Request and
Assignment Confirm. Accomplish this with a new subscr_conn_fsm that
parses and stores the original ass_req / ass_conf messages, communicates
with the BSCNAT MGW, and then creates new ass_req / ass_conf messages
based on the original ones but with new RTP information.
With this patch it is possible to do a successful voice call with the
following network:
MS1 --- BTS1 --- BSC1 --.
| | BSCNAT ----------- MSC
| | | | |
'-- MGW-BSC1 --|-- MGW-BSCNAT --- MGW-MSC
| |
MS2 --- BTS2 --- BSC2 --' |
| | |
'-- MGW-BSC2 ------'
