commit 1eaa3d72eaa10bb854b2adff48d3f7f3e06dcb8c Author: Holger Hans Peter Freyther holger@moiji-mobile.com Date: Mon Sep 21 11:28:03 2015 +0200

audio/rsl: Honor the speech mode and don't send anything

Spotted by Ciaby while debugging an audio issue. Do not send anything to port==0 to the BSC/NITB. Look at the upper bits of the speech_mode to determine if sending is allowed. 0x1 means recv_only and all other modes allow us to send.

Manually verified with a single phone call with LCR bridge mode to send a CRCX early but a MDCX sendrecv later. The audio starts to flow after the MDCX message. Virtual Addr space didn't increase over 10 calls. The l1p_msg is freed by the caller.

The code might not re-set speech_mode from one call to another but if it is ever != 0 it can be expected that the BSC will always set it. This is because we do not (and don't want to) allocate the lchan dynamically on every usage.

Fixes: SYS#2111

audio/rsl: Include statistics for one call

Use the new libosmo-abis API to query the session for the statistics and then send it as a TLV element to the BSC. This can be used to do post processing about the call. E.g to figure out if no audio arrived at all.

audio/rsl: Include the connection identifier in the DLCX ind

I have traces that include the connection identifier in the DLCX indication.
