[asterisk-bugs] [JIRA] (ASTERISK-22417) RTP ports left open after using click to dial application

[Patrick Beaumont (JIRA)]

Patrick Beaumont commented on ASTERISK-22417:
---------------------------------------------

I've put the "patch" in to the production server with the problem. I'll be monitoring it over the next week and let you know how that goes.

If you want to reproduce this without using Siptapi I would have thought you could use any "click to dial" software that uses an INVITE then a REFER to initiate the call. I haven't tried any others myself but if I get time over the next week I'll look for some.

> This is very repeatable and if performed enough times Asterisk will complain about no longing being able to allocate RTP ports and will start rejecting calls.
> Performing a core restart appears to be the only way to release the ports.
