[asterisk-users] 1.4.1 - T38 Pass Through - Seeing some odd errors but the fax works.....

Hello List -

Here's the setup:

Mediatrix 1102 ATA (t38enabled) <--> Asterisk 1.4.1 <--> IP <--> SIP GW <-->
TDM

The T38 call comes up perfect - I see the initial invite, followed by G711,
Re-Invite, T38 establishes, Fax Completes, T38 Stops, Call Down.
here's the problem - I see the following in my console:

[Mar 19 05:09:38] WARNING[4745] chan_sip.c: Can't send 0 type frames with
SIP write

And don't know what it means :)
I also see timing errors:

[Mar 19 05:08:46] DEBUG[4745] channel.c: Internal timing is disabled
(option_internal_timing=0 chan->timingfd=25)

sip.conf has t38pt_udptl=yes for all peers and globally.
A copy of the debug file during this call is located
http://chrisaloi.com/static/DEBUG.txt

Anyone have any thoughts?
