You need to post debug logs (use https://pastebin.freeswitch.org/ and paste
the url here).

You can also try the option wait-dialtone-timeout = 0 (in freetdm.conf.xml
in the <analog_spans><span> section), so we don't wait for dial tone, then
in your dial string you can use freetdm/1/WW1234

Every upper case w (W) is a full second wait time, so the example above
would wait for 2 seconds before dialing. Setting dial-timeout to 0 ensures
the string is dialed, regardless of whether we receive dial tone or not.
