[Asterisk-Users] Asterisk Fax support using T.38

[Lilantha Karunaratne]

Yes while we agree on your point, if the requirement is to relay faxes over
a VoIP network by an operator, then we need to use FoIP methods via T.37 /
38. Do you know of anyone using * with T.38 on a commercial implementation?

 

 

Cheers!

T.37 actually isnt that bad.  When its 'fax' (ie analog data passed to
represent data) its TDM, however to cross the internet and reap cost savings
its effectively mime encoded and sent via SMTP.  This gives you the TDM
capabilities (no jitter, low latency, all the things faxes like).  The
combination of the two is appealing from a technical standpoint vs analog
fax over a network because of bandwidth savings, potentially easier to
distribute to multiple destinations, allows for TCP connections on a lower
QoS to be sent, etc.  At least appealing to me.

This also makes it easier to integrate into a unified messaging solution
because you would have the fax as an email at some point, delivery does not
have to be to another fax machine.
