[Freeswitch-users] Media got stuck after attended transfer...

For "only" sending and receiving that's true.

But my customer wants 2 things:
- Using HylaFAX as fax server, as there are a lot of client apps and other tools
- Connecting "real" fax machines using a Linksys/Cisco SPA2102 (as this is certified by their SIP/ISDN gateway vendor)

So I could really need t38 handling in FS to don't make things more complicated as they already are... J
Proxy mode doesn't work for me because it gives an error when resume-media-on-hold is set.

I think a better approach here is to use spandsp.  We already have some groundwork done for this.  If you are interested in contributing, please email consulting at freeswitch.org<mailto:consulting at freeswitch.org> and we can discuss further.

Hi,

one of my customers is willing to contribute for t38 integration.

The basic idea is to connect HylaFAX to FS:
  t38modem <-> FreeSWITCH <-> Media Gateway with t38 support
All this without media proxy.

Another idea might be to implement t38 origination/termination with a class 1 modem input/output for use with HylaFAX.

Do you know how much money we need to collect for t38 support?
How much time is needed for implementing this?

Thanks, Klaus

hi, any clue when can t38 be added?

"Eventually." :)  Of course, if we could get more to add to the bounty it might grease the wheels of innovation.

Of course, I was listening to my A.M radio the other day and they said that there was this new invention called the Internet that would let people send documents to each other electronically. Maybe you should look into that. Next thing you know they'll come up with telephones that people don't have to plug into the wall and can take with them in the car. ;)
