Hi All, Have been pulling my hair out trying to work out why we're getting a strange delay upon completion of a t38 fax using rxfax. Upon finishing the receiving of a fax, and sending BYE to the originator, freeswitch seems to keep the channel open for exactly 30 seconds then tries to issue another hangup. Have tried all sorts of things in dialplan, including moving the answer to before the hangup hook - I prefer the answer to be post hangup hook to aid in hunting to different servers in case of API call failures. What's also weird, 30 seconds after rxfax completes there are debug entries for time stamps in the CLI from calls in the past?!@ If I do a show channels at idle - there are 0 total freeswitch@7f9729cbe5af> show channels 0 total. ---------------------------- Dialplan as follows ---------------------------- <?xml version="1.0" encoding="UTF-8" standalone="no"?> <document type="freeswitch/xml"> <section name="dialplan" description="Incoming Fax"> <context name="public"> <extension name="Fax{{ destination_number }}"> <condition field="destination_number" expression="^({{ destination_number }})$"> <action application="set" data="api_hangup_hook=system /data/python/process_fax.py {{ uuid }} /tmp/{{ uuid }}.tif {{ formats }} --caller {{ caller }} --fax_result_code \\\${fax_result_$........................cut<file:///$%7bfax_result_$........................cut> <action application="answer" /> <action application="playback" data="silence_stream://2000"/> {% if subscription.verbose_logging %} <action application="set" data="fax_verbose=true"/> {% endif %} <action application="set" data="fax_enable_t38_request=true"/> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="fax_ident={{ subscription.rendered_fax_ident }}"/> <action application="set" data="fax_header={{ subscription.rendered_fax_header }}"/> <action application="rxfax" data="/tmp/{{ uuid }}.tif"/> <action application="hangup"/> </condition> </extension> </context> </section> </document> ---------------------------- Debug logs ---------------------------- 2018-08-13 05:41:39.127583 [DEBUG] mod_spandsp_fax.c:496 ============================================================================== 2018-08-13 05:41:39.127583 [DEBUG] mod_spandsp_fax.c:502 Fax successfully received. 2018-08-13 05:41:39.127583 [DEBUG] mod_spandsp_fax.c:526 ============================================================================== 2018-08-13 05:41:39.127583 [DEBUG] mod_spandsp_fax.c:276 FLOW T.38T FAX exchange complete 2018-08-13 05:41:39.127583 [DEBUG] mod_spandsp_fax.c:276 FLOW T.30 Call completed 2018-08-13 05:41:39.127583 [DEBUG] mod_spandsp_fax.c:276 FLOW T.30 HDLC signal status is Carrier down (-1) in state CALL_FINISHED 2018-08-13 05:41:39.127583 [DEBUG] switch_core_codec.c:248 sofia/external/61XXXXXXXXX@2xx.xx.xxx.xxx<mailto:sofia/external/61XXXXXXXXX@2xx.xx.xxx.xxx> Restore previous codec PCMA:8.
