Comments:	By: Asterisk Team (asteriskteam) 2020-06-04 11:58:03.044-0500 Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution. A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already.

Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

All updates are posted to the issue when they occur. By: George Joseph (gjoseph) 2020-06-04 12:41:09.949-0500 Pete, I can's reproduce this.  I did a build with chan_mobile but without chan_alsa and chan_mobile loaded fine (after I created a good config file). Can you give me the exact errors you get and a copy of your chan_mobile.conf file? By: Pete Kirkham (pkirkham) 2020-06-06 04:43:22.743-0500 Here are the error messages. I made chan_mobile a required in modules.conf so the load will abort. [Jun  4 18:23:49] VERBOSE[29797] loader.c: Loading chan_mobile.so.

Best regards, Pete By: George Joseph (gjoseph) 2020-06-08 08:36:20.355-0500 I just tried your config and had no problems.  The "Unable to listen sco listener socket" message would imply a permissions or environmental issue somewhere outside Asterisk.  Do you have Pulse Audio running?  What user does Asterisk run as? chan_mobile is in "extended" support which means it's supported only by the community.  I think your best bet at this time is to ask for help on the community forums.  https://community.asterisk.org. By: Pete Kirkham (pkirkham) 2020-06-08 09:28:56.353-0500 Thanks George. Asterisk is running as root since I'm only in a test environment. Since generating and loading chan_alsa solved the problem for me I don't have any other issue. So solved as far as I'm concerned. By: George Joseph (gjoseph) 2020-06-08 09:38:17.751-0500 Gotcha.
