IPA is naming these functions CRCX, MDCX, DLCX to follow
the naming of the MediaGatewayControlProtocol. Change the
code to go from BIND to CRCX (create connection) and from
CONNECT to MDCX (modify connection).
Connect indicates that it is only possible to call it once
while it is possible to call it more than once to modify
the audio parmaters and such. So the IPA terminology is
making a bit more sense here (now that we know it).
On channel mode modify and assignment command when using
the a multirate code the multirate configuration must be
present in the packet.
Add a parameter and add a warning when using it in a
broken way.
Allow to handle the channel requested differently based
on the NECI value for the "paging any" case. This will allow
to open a TCH/H, TCH/F depending on the neci mode.
Use the correct length when going over the array instead
of using the neci0 values. Remove the fixme from the method
as well as the issue has been addressed by adding a parameter
to the method.
Be able to send RR CHANNEL MODIFY from the BSC/MSC code
as well. Move the method that knows about the IPAccess RTP
and issues the "bind" to the utils tool
Add code to generate an assignment command for a given lchan. It
is expected that the lchan is modified already and the mode will
be picked up from their. Currently only the mandantory items
are supported.
Add one method to extract the MI which will allow to load
the gsm_subscriber depending on the MSC/BSC setup and then
use gsm48_handle_paging_resp to finish the paging response
handling.
Prefix generate_mid_from_tmsi with a gsm48_, create a new method
to binary encode the imsi. Add a unit test for parsing and decoding.
The implementation can parse the data it generated and the
last octet seems to be filled with the end mark.
The existing gsm_04_08.c implementation is mixing BSC and MSC
behavior. Move some simple parsing and generation functions over
to gsm_04_08_utils.c to allow a different MSC to define the policy.
