[Asterisk-biz] T.38 pass-through / T.38 support

[Preston Garrison]

Why not use a proxy, in theory it should pass through t.38 just fine 
since it doesn't get involved in the RTP streams at all.  Is there a 
reason you need support DIRECTLy into asterisk.  I was thinking about 
adding proxy support to chan_sip for some time now, but have ended up 
making a stand alone proxy solution, and a universal system to 
authenticate users via asterisk or my proxy system, as well as DIDs 
etc.  This way I can hand off my sip connections to asterisk if needed 
for voicemail etc, but most of the times my calls just pass through my 
proxy server only.

Hello,

  I am looking for a programmer(s) that would like to be paid to 
implement either:

 1) T.38 pass-through support for chan_sip in Asterisk

 or

 2) T.38 support defined as:

  1. support for cisco-interop T.38 from Zap channel to SIP [call 
originates on Zap channel, your T.38 implementation would convert Zap 
channel data to SIP RTP T.38 protocol to Cisco AS5400 HPX through 
Asterisk -- I can give you access to a test Cisco as well as Asterisk 
with Zap ISDN channels]

  2. support for SIP using cisco-interop T.38 back to Zap [call comes 
into Asterisk on chan_sip via T.38, converted back into Zap channel 
over ISDN PRI to end-user fax].

  3. T.38 pass-through support for SIP-->SIP calls, meeting 
cisco-interop standards

  Your T.38 support only needs to be Cisco compatible, and work smoothly 
between SIP and Asterisk Zap channels.

  We are an established company with a budget big enough to compensate 
for this work fairly. Please contact me via email if you have a 
solution for sale now, or with any proposals to create one for us. If 
you submit a proposal, I need you to include a pricing quote as well as 
reasonable time to completion.

 Yours,
 Matthew Simpson
