Hi, I would like to improve my understanding of T.38.
1. What T38FAX_VERSION_0 or T38FAX_VERSION_1 in chan_sip.c means ? voip-info.org implies one has to change values in chan_sip.c to make it work. Shall I set T38FAX_VERSION_1 or leave T38FAX_VERSION_0 in global_t38_capability ? Source code says "This is default: NO MMR and JBIG trancoding, NO fill bit removal, transferredTCF TCF, UDP FEC, Version 0 and 9600 max fax rate" What does "Version 0" relates to in this aboxe line ? MMR and JBIG transcoding ? 2. A softphone like Zoiper is able to receive voice or fax calls. When setting those values (see bellow) in sip.conf, does it mean : "t38/udptl will be chosen if a fax signal is detected somewhere in the path. If none, then alaw would be picked" t38pt_udptl=yes t38pt_rtp=no t38pt_tcp=no disallow=all allow=alaw 3. How do you reload updtl.conf ? Regards
