Sorry for the late reply. Are you saying that if I configure a voice vlan, then that will mitigate against going past the 17th voip sessions? Are you saying that I should not be defining the ports as "Auto" but as "Static" under the web gui: Switch: VoiceVLAN: Port Setting: Voice VLAN Mode drop down menu, in order to avoid the 16 Auto VOIP session limit?
I already had defined a VLAN 230 for Voice and VLAN 10 for Data. I use DSCP instead of COS.
Below is an excerpt for a PC6248 (that we use as the core) hence no real mention of voice vlan. Right after that is an excerpt for a PC5448 that is an edge switch (connected to the core via LAG) for the phones so lots of voice vlan settings.
Thanks for the reply Daniel, I have checked out those two links before (the 6248 user guide and the 6200 Voice VLAN support). I have another PC6248 acting as an edge switch for a couple of phones and this switch does not have the Auto VoIP enabled in Quality of Service > Auto VoIP > Global Configuration and yet when I view the interface config, I see every port having Auto VoIP mode enabled. So why have a global config? Is it to massively set all the ports to enable?
If I set the ports to not be Auto VoIP mode enabled, would that avoid hitting the 16 AutoVoIP limit?

That should work, if auto VoIP is not enabled it shouldn't hit the limit.

Thanks for the reply Daniel, I have checked out those two links before (the 6248 user guide and the 6200 Voice VLAN support). I have another PC6248 acting as an edge switch for a couple of phones and this switch does not have the Auto VoIP enabled in Quality of Service > Auto VoIP > Global Configuration and yet when I view the interface config, I see every port having Auto VoIP mode enabled. So why have a global config? Is it to massively set all the ports to enable?
If I set the ports to not be Auto VoIP mode enabled, would that avoid hitting the 16 AutoVoIP limit?
