[asterisk-users] FAX

[Danny Nicholas]

Good new is "your'e getting somewhere".  Bad new is - you have to modify
rtp.c to allow this codec.  You should be able to duplicate a line (around
1390) and change the value from 

[34] = {1, AST_FORMAT_H263},

To 

[100] = {1, AST_FORMAT_H100},

 

Then just do a make && make install on asterisk again.

Doesn't matter - the call-limit is important because 1 call can actually be
2-N hops.

Try increasing (or adding) call-limit on sip.conf.

You need to determine what codecs are expected (sip set debug on from CLI).
Commenting out the disallow=all lets * use any available codecs, but may
slow down the process or cause undesirable results by using/accounting for
unneeded or unwanted codecs.

Dear Sir,

 

What do you mean by manual fax? I need to offer the ability for each
extension to use voice and FAX...MAybe the voice will use G729 and the FAX
ulaw for the same extension...If I configure the device in a manner that use
ulaw for FAX and G729 for voice then this should work smoothly with an
extension where G729,ulaw, alaw are allowed?

 

Regards

The codecs should only be needed for a "manual" fax, where a voice
interaction might be expected or anticipated.

Dear Sir,

If I commant all codecs including disallow=all, then which codec should I
define on the extensions from where I'm trying to send FAX?
