Yes, the LAN has QoS prioritization and it is on a separate VLAN from the data network. >> I recently read another thread about a user hearing a stutter during >> voicemail IVR playback.

That's what I was on before 3.2.4. I can also try 3.2.5 if you recommend that over 3.1.3RevC. >> >> I know there are many tests I can run but what are some of the best >> tools/tests to run in order to track down the cause of an issue like >> this?

The VOIP is insulated from everything else by VLAN and QoS. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
