Hi, we seem to have an ongoing issue with sonicwalls and MGI ports not clearing down. Over a period of a few months they become locked up, connection status will show the mgis connected to the sip trunk port numbers but no calls exist. SIP trunks are setup using 833 peering.

It seems to affect all sites running sonicwalls of different varieties all all versions of the OAS and 4.70> software

Has anyone else come across this issue?

Samsung UK are unaware of it?
