Does anybody notice the same problem with verison 1.2.8
libpri(bristuff-PRE-1y-w) which should be fixed with Tzafrir Cohen`s SABME
bug fix in libpri 1.4.3-2? As for me, i still noticed wrong SAMBE/UA
handling in 1.2.8. But im afraid of patching 1.2.8 because of this comment
cout line in 1.2.8 sourcecode:
/* Send Unnumbered Acknowledgement */
q921_send_ua(pri, h->u.p_f, h->h.tei);
// if (pri->q921_state[teio] == Q921_LINK_CONNECTION_RELEASED) //
this breaks stuff!
return q921_dchannel_up(pri, h->h.tei);
} else if (h->u.m2 == 0) {
/* It's a UA */
Does anybody know why this should break stuff and if i savely could patch
this version too ?
[ Tzafrir Cohen ]
* Fix layer 2 startup bugs (e.g. resume from cable disconnect) on BRI lines:
- When getting a SABME/UA after sending one, don't reset state.
- Don't further process an unassigned TEI event.
