Dear Friends Pls Help me...... I am unable to send and receiving fax directly between two zoiper peer i.e 1001(zoiper peer) --->FS---->1002(zoiper peer) using spandsp module. My actual test scenario is,I dial 1002 from 1001 with selecting some.tiff file,and fax should be send to 1002.but this scenario is not working in zoiper. I also try another scenario.By dialing 555 and try to set some T.38 variable and then bridge the call to 1002 for sending fax. <extension name="555" continue=true> <condition field="destination_number" expression="^(555)$"> <action application="answer"/> <action application="set" data="fax_enable_t38=true"/> <action application="export" data="fax_enable_t38_request=true"/> <action application="set" data="execute_on_answer=t38_gateway self nocng"/> <action application="bridge" data="user/1001"/> </condition> </extension> but this scenario is also not working. pls help me resolved my problem soon.
