Greetings,

I've attached a BB8700 onto my openBSC and GSM wise, everything works well
after a reboot or two concerning "SIM: Call Barred".

One issue I am seeing is that it does not bring up GPRS/EDGE.  NITB console
shows a DATA INDICATION followed by a RELEASE INDICATION.

SGSN shows the following when attaching to the network:
<0012> gprs_bssgp.c:347 BSSGP TLLI=0x7f5bff3f Rx UPLINK-UNITDATA
<0013> gprs_llc.c:478 LLC SAPI=1 C   FCS=0xf80758CMD=UI DATA
<0013> gprs_llc.c:742 LLC RX: unknown TLLI 0x7f5bff3f, creating LLME on the
fly

the handset never reaches GPRS mode.

Any ideas?  PCap available upon request.

Cheers,
-Don
