[asterisk-dev] trunk 33972 and t38

[Steve Underwood]

Hi Matthew,

As you can see from the failure of trunk to even compile (it fails for 
me too) trunk is in a state of flux, as they try to merge stuff for the 
first 1.4betas. I could take you money, but until things settle a bit I 
couldn't provide any value for money.

My T.38 passthrough stuff is now working pretty well. We've sent and 
received quite a lot of faxes using versions of rxfax and txfax upgraded 
to support T.38 as well as audio streams. chan_sip needs to behave in a 
more active way to make it start up properly in all circumstances - 
currently it just passively wait for another party to kick T.38 into 
life. However, with setups where the other party will kick it, the 
latest snapshots of spandsp seem to be working pretty well.

T.38 gateway mode is also working fairly well now. However, the 
appropriate way to integrate that is not so clear. I am testing with a 
rather fudged in approach right now.

Steve
