Since no one else has responded I'll chime in with some general advice.

It's troubling to see that your "provider" is using Asterisk to face
you (the customer).

I've never had any luck getting T.38 to work (at all, in any mode)
using Asterisk. I've heard of other people making it work but
consider the chain here:

Their provider (they appear to be using DIDx, hmmm) -> Callwithus
(using Asterisk) -> You (FreeSWITCH) -> Your device

I don't see anything specific in your case but there are many, many
places for T.38 to go wrong in this scenario. I'd recommend
attempting T.38 against a local gateway or known Tier 1 provider
supporting T.38 with known equipment.

Otherwise, do you have any updates for us?

Hello.

I want to set up faxing via the gateway linksys spa-3102 (with support
for t38) via SIP.

SIP-client -> linksys spa3102 -> fs -> provider

<gateway name="callwithus">
....
<param name="inbound-late-negotiation" value="true"/>
<param name="stun-enabled" value="true"/>
</gateway>

<extension name="Fax">
<condition field="destination_number" expression="^(30)(\d{11})$">
<action application="set" data="proxy_media=true"/>
<action application="set" data="bypass_media=false"/>
<action application="bridge"
data="sofia/gateway/callwithus/*4087$2@sip.callwithus.com"/>
</condition>
</extension>

I make a call, press start on the fax. Fax not sent. Get this in the log
(UA freeswitch not trunk-12805):

Gafachi has T38 fax support.

Since no one else has responded I'll chime in with some general
advice.

It's troubling to see that your "provider" is using Asterisk to face
you (the customer).

I've never had any luck getting T.38 to work (at all, in any mode)
using Asterisk. I've heard of other people making it work but
consider the chain here:

Their provider (they appear to be using DIDx, hmmm) -> Callwithus
(using Asterisk) -> You (FreeSWITCH) -> Your device

I don't see anything specific in your case but there are many, many
places for T.38 to go wrong in this scenario. I'd recommend
attempting T.38 against a local gateway or known Tier 1 provider
supporting T.38 with known equipment.

Can you advise sip-providers offering t38?

No. I can not add anything.

Hello.

I want to set up faxing via the gateway linksys spa-3102 (with
support
for t38) via SIP.

SIP-client -> linksys spa3102 -> fs -> provider

<gateway name="callwithus">
....
<param name="inbound-late-negotiation" value="true"/>
<param name="stun-enabled" value="true"/>
</gateway>

<extension name="Fax">
<condition field="destination_number" expression="^(30)(\d{11})$">

<action application="set" data="bypass_media=false"/>
<action application="bridge"

</condition>
</extension>

I make a call, press start on the fax. Fax not sent. Get this in
the log
(UA freeswitch not trunk-12805):
