Me too! It happened on 4.2.1 with pcom firmware 3.2.4 and still with 4.4.0 and 3.2.5. After going through some traces, we replaced an old cat 5 drop with several cross connects with a cat 6 home run it seems. To have helped. -----Original Message----- From: Tony Graziano <[email protected]> Sender: [email protected] Date: Thu, 16 Jun 2011 12:29:05 To: Discussion list for users of sipXecs software<[email protected]> Reply-To: Discussion list for users of sipXecs software <[email protected]> Subject: Re: [sipx-users] Problem with internal calls Polycom to Polycom - PRACK missing

It also happens on incoming trunk calls. In the one instance where it is happening we're in the process of replacing a crappy switch though, and I wanted to get that out of the way before I pointed fingers. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/ _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
