Hi, I have a problem with fax in asterisk version 1.2.7. The application rxfax doesn't work triggering these errors : channel.c: Dropping incompatible voice frame on ... of format slin since our native format has changed to ulaw chan_sip.c: sip_write: Asked to transmit frame type 64, while native formats is 4 (read/write = 4/4) I think it's a problem of transcoding from ulaw to slin but I can't see how to fix it : which file .c i must modify or ....!! Can anyone please tell how to solve this problem?!! Thank u very much in advance _________________________________________________________________ Windows Live Mail : d?couvrez et testez la version b?ta ! http://www.ideas.live.com/programpage.aspx?versionId=5d21c51a-b161-4314-9b0e-4911fb2b2e6d
