<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hi Guys,<br>
<br>
I need to bridge an FXS port (when taken off-hook) to an FXO port without<br>
dialing any digits like so:<br>
<br>
<action application="bridge"
data="freetdm/span_fxo_csd/1"/><br>
<br>
This results in the following error:<br>
<br>
ftmod/ftmod_analog/ftmod_analog.c:<br>
<br>
if (ftdm_strlen_zero(ftdmchan->caller_data.dnis.digits)) {<br>
ftdm_log_chan_msg(ftdmchan, FTDM_LOG_ERROR, "No Digits to
send!\n");<br>
<br>
For now I have worked around this by using<br>
<br>
<action application="bridge"
data="freetdm/span_fxo_csd/1/w"/><br>
or<br>
<action application="bridge" data="freetdm/span_fxo_csd/1/F"/><br>
<br>
I would like to avoid the unnecessary delay this incurs.<br>
<br>
Any suggestions? Under what circumstances is it bad to send zero digits? Can<br>
I simply take out the check for zero-length dnis.digits?<br>
<br>
Cheers,<br>
-Slim<br>
