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. The guidelines detail what is expected from an Asterisk issue report. Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

Tested on 15.5.0 and two clients: MicroSIP, Groundwire (has REFER feature) By: Richard Mudgett (rmudgett) 2018-07-31 06:38:17.062-0500 We suspect that you have a deadlock occurring within Asterisk. Please follow the instructions on the wiki [1] for obtaining debug relevant to a deadlock. Once you have that information, attach it to the issue. Be sure the instructions are followed exactly as the debug may otherwise not be useful. Thanks! [1] https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace#GettingaBacktrace-GettingInformationForADeadlock The REFER in question is for a blind transfer not an attended transfer so the external_replaces extension does not apply anyway. By: Dmitriy Serov (Demon) 2018-07-31 07:24:52.379-0500 It is not deadlock. It is segfault. Archive is attached By: Joshua C. Colp (jcolp) 2018-07-31 07:28:48.353-0500 That appears to be a duplicate of ASTERISK-27481 which has a workaround - res_pjsip_pubsub has to be loaded. By: Dmitriy Serov (Demon) 2018-07-31 07:41:47.132-0500 Yes. It seems to be duplicate of... What can i do to disable process of SUBSCRIBE/OPTIONS events instead of disabling res_pjsip_pubsub? After refactoring of OPTIONS processing where are some bugs (hangs and segfaults) that i have not time to collect data to file issue :( By: Joshua C. Colp (jcolp) 2018-07-31 07:45:15.355-0500 The res_pjsip_pubsub module has nothing to do with OPTIONS. Disabling qualify disables that. Endpoints have an "allow_subscribe" option which can be used to disallow them from subscribing. | ||||
