Description:	CVS-HEAD now shows the following messages on outgoing calls: Nov  4 18:13:02 WARNING[9057]: chan_zap.c:7179 pri_fixup_principle: Call specified, but not found? Nov  4 18:13:02 WARNING[9057]: chan_zap.c:7823 pri_dchannel: Ringing requested on channel 0/1 not in use on span 1 The result of these is if a call is time-limited (i.e. Dial(Zap/g0/2345678,30), even if the call is answered, Asterisk will timeout the call (because it isn't detecting the answer). ****** ADDITIONAL INFORMATION ****** Signalling type is ni2. Reverted libpri and chan_zap.c to CVS-10/28/2004 and everything works fine.
Comments:	By: Brian West (bkw918) 2004-11-04 21:06:09.000-0600 I have seen this too but to quote Mark himself: "That suggests that there is ringing being requested on a call that isn't active." I believe otherwise. bkw By: Mark Spencer (markster) 2004-11-04 21:06:46.000-0600 Did you make clean ; make install on both libpri and asterisk? By: Mark Spencer (markster) 2004-11-04 21:11:14.000-0600 Also, please trace it to an exact patch in either chan_zap or libpri. By: Brian West (bkw918) 2004-11-04 21:44:57.000-0600 I did... both... :P  Same problem...  I'll try to trace it back. bkw By: Tilghman Lesher (tilghman) 2004-11-04 22:27:47.000-0600 The problem appears using libpri/q931.c 1.94, but not with 1.93.  I've tracked down that I can change ONLY libpri to make this problem appear or go away. By: Brian West (bkw918) 2004-11-05 09:55:08.000-0600 Ya know this bug is Major in my view... By: Paul Cadach (pcadach) 2004-11-05 11:50:39.000-0600 As you can see there is works with latest libpri. Check chan_zap patch attached for solution. No other changes it made for libpri/chan_zap at my box. Also, Asterisk tree is slightly outdated, but libpri is CURRENT (updated 10 minutes ago). By: Paul Cadach (pcadach) 2004-11-05 12:02:21.000-0600 Checked latest Asterisk tree together with latest libpri. All fine. See latest.log. By: Paul Cadach (pcadach) 2004-11-05 12:10:07.000-0600 PS: Signalling is EuroISDN, not NI2, but pointed changes at libpri isn't related to signalling... Tested with switchtype=national - all ok. By: Tilghman Lesher (tilghman) 2004-11-05 13:25:46.000-0600 Version skew.  Not sure what it was before, but PCadach's guidance on IRC helped find the problem.
