Description:	1.6.1-beta4: pstn connected to TDM400P. The sender is the office fax ( Brother ) used daily without problems. I can receive faxes with the pstn hooked up to my fax machine. A one page fax works fine, but two pages causes an error. Same problem whether using * built with and using spandsp-0.0.5-pre4 or built with and using 0.0.6-pre3, but different error messages: 0.0.5-pre4:    -- Executing [fax@incoming-pstn-line:1] NoOp("DAHDI/4-1", "Fax Detected") in new stack    -- Executing [fax@incoming-pstn-line:2] Goto("DAHDI/4-1", "incoming-fax,s,1") in new stack    -- Goto (incoming-fax,s,1)    -- Executing [s@incoming-fax:1] Set("DAHDI/4-1", "FAXFILE=/var/spool/asterisk/fax/200901161227-0") in new stack    -- Executing [s@incoming-fax:2] ReceiveFAX("DAHDI/4-1", "/var/spool/asterisk/fax/200901161227-0.tif") in new stack [Jan 16 12:28:58] WARNING[24687]: app_fax.c:177 phase_e_handler: Error transmitting fax. result=49: The call dropped prematurely.

Same problem with two pages, and now it errors out with ONE page.  The error message is like 0.0.5-pre4 - result=49:    -- Executing [s@incoming-fax:1] Set("DAHDI/4-1", "FAXFILE=/var/spool/asterisk/fax/200901201802-0") in new stack    -- Executing [s@incoming-fax:2] ReceiveFAX("DAHDI/4-1", "/var/spool/asterisk/fax/200901201802-0.tif") in new stack [Jan 20 18:03:15] WARNING[3719]: app_fax.c:177 phase_e_handler: Error transmitting fax. result=49: The call dropped prematurely.

By: Leif Madsen (lmadsen) 2009-04-01 19:52:40 I'm suspending this issue due to lack of inactivity. If someone can provide the requested information either re-open the issue (if you're the original reporter) or find a bug marshal on #asterisk-bugs on the Freenode IRC network at irc.freenode.net. Thanks!
