[mgcp] Add a simple mgcp gateway used for the BSC
The python script is a simple call-agent driving the
client. Currently it is sending a AuditEndpoint message
and is printing the result.
The bsc_mgcp.c is a standalone process that will implement
a MGCP Gateway for the MSC. On call handling the Call-Agent
will ask the Gateway to "CreateConnection" and then this
gateway needs to communicate with OpenBSC.
Currently CreateConnection,ModifiyConnection,DeleteConnection
and Endpoint auditing is implemented.
[mgcp] Send RSIP on start and on first receive of any message
Ignore the first request and send a RSIP. We do that because
we might tunnel UDP through some other things and have no direct
way to connect to the call-agent.
Also the transaction is not checked and we ignore the response
from the call-agent, actually we print the '200 ' or any other
value as unhandled...
[mgcp] Print the MGCP command next to the response code
This allows to see which commands were sent by the server
mgcp: Terminate it with a new line
[mgcp] Make number of endpoints static...
For now this is fixed to the number of endpoints as of the GSM
specification...
[mgcp] The endpoint names seem to be base 16... use strtoul to parse
Use strtoul to parse the base 16 number from the mgw string.
[mgcp] Log the endpoints as hex numbers...
[mgcp] Only send the RSIP on the first incoming message..
Remove call_agent option (also remove the number from the getopt
call).
[mgcp] Start couting at 1 for the mgcp
[mgcp] Slight attempt to improve the grammar of the strings
[mgcp] Share validation routines between DLCX and MDCX
[mgcp] Remove help for dead config options
[mgcp] Specify a different IN addr in the SDP records
In case of NAT traversal be able to listen on a given
interface (like 127.0.0.1) but claim to receive data
at the beginning of the tunnel.
[mgcp] Fix the static copy of the SDP file
WIP verify out factoring broken..
[mgcp] Introduce VTY to the mgcp for config file parsing...
Parse the MGCP config file via the VTY framework.
[mgcp] Handle SDP parameters through VTY..
Currently the payload type, name and rate can be specified
in the config file.
[mgcp] Add an option to bind all rtp ports early
This can be useful for testing and in deployment to make sure
no runtime resource limit can be hit.
[mgcp] Add some API doc comment
[mgcp] Convert the packets of the example server to ascii
This will allow to easily patch the call id... to run the
server in a loop and make it work with the mediagateway
[mgcp] Assign CI_UNUSED... to be more obvious...
[mgcp] Use DEBUG and not DEBUGPC and specially not printf
Improve the logging a bit in the mgcp
[mgcp] Change the fake server to change the call id
This assume the call-agent will just increment the id
as well.... this is true for our implementation
[mgcp] Generate the transaction id dynamically..
This way wireshark will be more happy about it...
[mgcp] Recognize responses from the network..
This is just recognizing the response code and
then is doing nothing with it. Also change the
script to generate response messages...
[mgcp] Improve debug messages for CRCX/MDCX..
Log on which ports the media gateway is listening
and where the other (server) gateway is located
