Freeswitch 1.10.7 faxing with mod_spandsp not hanging up. #1640

Open JonathanAldridge opened 2 years ago

JonathanAldridge commented 2 years ago

I'm setting up a Freeswitch 1.10.7 server on Debian Buster, and when sending faxes using "originate" the fax goes through, but the call is never hung up. The last few lines in the log are: 2022-04-22 18:44:38.495611 95.90% [DEBUG] mod_spandsp_fax.c:302 FLOW T.38T FAX exchange complete 2022-04-22 18:44:38.495611 95.90% [DEBUG] mod_spandsp_fax.c:302 FLOW T.30 Call completed

Now I have a working copy of this under Freeswitch 1.6, and that works fine with the same lines in the log being: 2022-04-22 18:18:41.387086 [DEBUG] mod_spandsp_fax.c:276 FLOW FAX FAX exchange complete 2022-04-22 18:18:41.387086 [DEBUG] mod_spandsp_fax.c:276 FLOW T.30 Call completed 2022-04-22 18:18:41.387086 [DEBUG] switch_core_codec.c:248 sofia/external/61xxxxxxxxx Restore previous codec PCMA:8. 2022-04-22 18:18:41.407127 [NOTICE] switch_core_state_machine.c:385 sofia/external/61xxxxxxxxx has executed the last dialplan instruction, hanging up. 2022-04-22 18:18:41.407127 [NOTICE] switch_core_state_machine.c:387 Hangup sofia/external/61xxxxxxxxx [CS_EXECUTE] [NORMAL_CLEARING] …

So for some reason it's just not proceeding to the hangup stage.

The originate command was: originate {origination_caller_id_number=61280768078,fax_header='To: Spare inbound From: Tarsier Computing - ',fax_ident='61280768078',fax_disable_v17=false,fax_enable_t38=true,fax_enable_t38_request=true,ignore_early_media=true,absolute_codec_string='PCMA,PCMU',fax_verbose=true,fax_use_ecm=true,data_jobref='45848464',data_intid=17}sofia/gateway/simtex_sip.com/61291996515 &txfax(/var/www/freeswitchbackend/Data/temp_convert/1650536104.6437853/output_tif.tif)

I'm using the default config files and dialplans, with the only change the SIP profile and RTP port config.

The log of the Fax is attached: Freeswitch_fax_log.txt

Is there any other info needed from me?

Regards, Jonathan A.

Same issue in some t38 cases.

This issue appears to still be lingering in 1.10.11. Any solution?
