[asterisk-bugs] [JIRA] (ASTERISK-25065) SRTP failing over time

[Sam Ultima (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=226157#comment-226157 ] 

Sam Ultima commented on ASTERISK-25065:
---------------------------------------

The fastest way we could reproduce problem was to make a conference call (to any number-voicemail in our case) and place it on hold. Once we attempt to retrieve call from hold, there is complete silence/no audio. Further call attempts result in fast busy signal on phone and above error messages.

> From all appearances, SRTP appears to function except over time, calls begin failing. Temp solution is to restart phone and resume calls after registration.
> Debug shows the following errors:
