Certain phones with GPRS capabilities will fail to initiate calls with the following error. No call output will be present in the Asterisk log. 1265648543.0255 INFO 3073350512 GSML3Message.cpp:162:parseL3: L3 recv RR GPRS Suspension Request 1265648543.0257 NOTICE 3073350512 DCCHDispatch.cpp:144:DCCHDispatcher: UnexpectedMessage The issue and patch were discussed on the openbts-discuss mailing list. "David is right that openBTS does not emit any GPRS beacon, so the behaviour is triggered from mobile station which believe that there has been some GPRS before (i.e. in it's old location area). Unfortunately openBTS does not simply ignore this L3 RR GPRS Suspension Request, instead a expected message flow sequence (i.e. during call setup) is terminated with an exception. However we created a small patch against openbts-2.5.3 Lacassine to really ignore the L3 message. Feel free to distribute it upstream to the community." The author of the patch is >> Florian.Wolff@Siemens.com << According to his statement, O2 XDA Orbit and Motorola Milestone are working fine with those changes. They had the same problems before as with the iPhone. Reported-by: Michael Folz <michael.folz@fh-kl.de> Signed-off-by: Thomas Tsou <ttsou@vt.edu> |
