openbts-2.8's Issues

Emergency Call

Hi, good morning!

I would like to ask you first of all if this projects is still alive? If yes, the next question I would like to ask is about the support to emergency calls for this version (2.8) Is is supported or this version does not have any support for this?

Thank you so much in advance!

Crash: Wrong assert() in SIP::SIPEngine::MODSendERROR()

Function SIPEngine::MODSendERROR() tries to access associated INVITE and checks that it exists with assert(), which leads to a crash when this happens. this should be fixed and either assert replaced with a graceful error check or the condition to be checked by a caller.

openbts-2.8/SIP/SIPEngine.cpp

Line 733 in 386f5a0

assert(mINVITE);

From the user report:

This is the log after a successful transmission of sms:

'VERSION' was not declared in this scope sprintf(tag, "OpenBTS %s Build Date %s", VERSION, __DATE__);

hello i'm working on openBTS 2.8 currently and when i put the make command i get this error:

make[2]: Entering directory `/home/openbts/openbts-2.8/SIP'
CXX SIPMessage.lo
SIPMessage.cpp: In function 'void openbts_message_init(osip_message_t**)':
SIPMessage.cpp:50:43: error: 'VERSION' was not declared in this scope
sprintf(tag, "OpenBTS %s Build Date %s", VERSION, __DATE__saut

can you help me or orient me on this problem?

openBTS crashes when BYE is not ack'd

occurs randomly.
when call is being terminated due to RR failure, and all BYE messages are unack'd, in MODWaitForBYEOK(), gSIPInterface.read() returns an invalid pointer. No timeout exception is thrown..

BladeRF Support

Hi,

Have you try this OpenBTS build running on BladeRF?
I've generated the transceiver according to this: https://github.com/Nuand/bladeRF/wiki/Minimalistic-build-and-run-test-for-OpenBTS-5

Appears this error:

Stealing bits handling and UPFER

UPFER value is calculated improperly if stealing bits are present. This is most visible on BlackBerry phones, which continuously send some bursts with stealing bits during a call.

The suspected reason is that packets with stealing bits set are always counted as bad frames, even though they are valid FACCH frames.

Another possible reason is that they are normal TCH bursts with erroneously set stealing bits (we've seen only one stealing bit set during a call on BlackBerry).
