Description: | iam realy suprised, why fax can't pass through inside DAHDI bridge looking through chan_dahdi.c code inside function dahdi_bridge have a code f = ast_read(who); if (!f || (f->frametype == AST_FRAME_CONTROL)) { *fo = f; *rc = who; res = AST_BRIDGE_COMPLETE; goto return_from_bridge; } if (f->frametype == AST_FRAME_DTMF) { if ((who == c0) && p0->pulsedial) { ast_write(c1, f); } else if ((who == c1) && p1->pulsedial) { ast_write(c0, f); } else { *fo = f; *rc = who; res = AST_BRIDGE_COMPLETE; goto return_from_bridge; } } ast_frfree(f); /* Swap who gets priority */ priority = !priority; i see that only the SIGNAL FRAMES can pass | ||

Thanks for the submission! By: Leif Madsen (lmadsen) 2010-06-03 11:00:09 Can we get some clarification about which version of chan_dahdi you are using? Some more information about the call along with with console logging and debug, plus the chan_dahdi.conf configuration will be required to move this forward. By: ddkprog (ddkprog) 2010-06-05 00:54:23 version does not have a value bug is present in all versions of chan_zap.c/chan_dahdi.c this patch fixit version svn trunk chan_dadi.c I can not provide debug and configuration because I have not access to equipment but this patch is used for passing faxes in the channel dahdi in working with channel bank where chan_dahdi channel operates as a function of dahdi_bridge() I think for the developer chan_dadhi this logic more than transparent because frames T30 are not AST_FRAME_CONTROL/AST_FRAME_DTMF so at least the AST_FRAME_AUDIO and AST_FRAME_VIDEO should be pass throught inside dahdi_bridge() function the patch fixes this issue and frame T30 will pass throught inside DAHDI By: Russell Bryant (russell) 2010-10-15 11:56:18 What doesn't make sense here is that if DAHDI bridging was really broken in this fundamental of a way, then we would have thousands of customers with systems that don't work at all. I wouldn't expect any media frames to be passing through the dahdi_bridge() function. If this funciton is running, it's a DAHDI native bridge. A DAHDI native bridge bridges audio inside of DAHDI, it doesn't even make it up to Asterisk. By: Russell Bryant (russell) 2010-11-03 13:58:18 Thank you for the bug report. However I am unable to reproduce this issue. We are now going to close this report - please feel free to reopen when you have more information at hand. |
