[Asterisk-Users] Asterisk rxfax(): One page gets two pages
Hi, so far I had our PRI line connected via Digium TE410P and ZAP channel to asterisk which worked perfectly. I now have a second line coming in through a H.323 gateway and chan_oh323. rxfax() still works and receives faxes with G.711 alaw codec, but I always get one empty first page via H.323 - a one-page-fax becomes a two-page-fax with one empty page in front of it. It seems the empty page is only one scanline long. I am using asterisk CVS head of 2004-06-01 and spandsp-0.0.1k. A logfile from the console is attached below. May I kindly ask you to have a quick look at it?
