Harald Welte 7f93ceafef Ignore CONNECTION FAIL INDICATION cause 0x18 to make sure our phone calls survive on BS11. 
Apparently the BS-11 sends soem undocumented cause 0x18 as part of a CONN FAIL IND message
shortly after we establish the call.  If we close the channel, the voice call
is aborted. If we ignore the message, everything just continues to work.

Harald Welte b49fe96ad6 reduce lag in voice calls by reducing the subchannel muxer tx queue depth to 
effectively three entries.  In the future we should probably think of only
having a one-frame deep queue.

Harald Welte f9227c7562 write 160byte to one E1 TS at any given time, since that is one TRAU Frame (40 bytes) per sub-channel 2009-02-18 03:39:00 +00:00

Harald Welte 7ccf77810b slightly more complete GSM 04.08 CC, we can now 
* initiate phone calls from one MS
* look-up the subscriber based on dialled extension
* page the called subscriber
* send the SETUP to the called subscriber, including CLIP/CLIR
* get ALERTING notification back to caller
* relay DISCONNECT from either side to the other
This is still far from being complete, but it at least works for the most common case
