Yeah, so that's the issue. The portable phone is currently plugged into the "PC" port on the phone. Before this firmware update, that wasn't a problem since I wasn't making use of the "Voice VLAN" value on the switch port, and the "VLAN" value was just set to the voice VLAN value. Now that it seems I'm required to use this field, it looks like I'll need to connect those portable phones to their own port on the switch and use the voice VLAN value just as I did for the desktop phones.

@RichG, this seems to have done the trick. Quick question, though. The VOIP phones have two ports: "Internet" and "PC". The "PC" port on most of our phones is unused since our PCs are plugged directly into their own port on the switch (and on a separate VLAN). However, I do have a few portable IP phones that I currently have plugged into the "PC" port of the phone. In this case, should both VLAN and Voice VLAN be set to the voice VLAN value?

@RichG, I just populated a dummy value in the "VLAN" field and used the correct VLAN number for the "Voice VLAN" field, and it's all working. Interesting that this was never required before, but I'll do some validation both in the office and with the vendor before making this change on all of my phone ports. Thanks for the tip!

Thanks, @RichG. Right now, I only have the VLAN field populated with the correct VLAN. I will switch to using the Voice VLAN field and see if that helps. This isn't something I ever had to do before, though, so it would be new. Still, I'd rather manage these things on my side as opposed to waiting for the VOIP provider to get around to it. I'll try it and report back.

You beat me to it! I went ahead and removed the DHCP reservation from my phone. Upon a resync, the phone came up and it failed to register. I rebooted the phone again, but the problem persisted. From the admin interface of the phone, I went in and disabled LLDP and CDP, rebooted, and voila, the phone registers and comes back up. I've asked the vendor for their guidance on this, but this seems to be a firmware issue. Thanks.

Totally agree, and I'm working on that with them. Still, from the phone's perspective, what is it seeing differently about the network when the IP address is reserved versus when it's just dynamically assigned?

I'm experiencing an odd issue, and I was wondering if anyone in the community has seen this before. We have Meraki MS-350 switches running firmware 14.33. We are using Yealink T48S VOIP phones with GoToConnect as our service provider. The desk phones are on a separate VLAN and DHCP is enabled on the VLAN. After a recent desk phone firmware update, our desk phones are unable to successfully register with GoToConnect upon rebooting. I am able to ping the phone and access its web GUI from my desktop PC VLAN. The phone certainly appears like it is functioning normally on the network except for registering with the provider. The workaround is to either set a static IP address on the phone or to reserve the IP address on the Meraki switch. If either of those things are done, the phone comes up and registers without a problem. If I remove the IP reservation and reboot the phone, it will grab another IP address and fail to register again. I cannot understand why this might be. My gut feeling is that this is a bug in the phone firmware, but the VOIP provider hasn't been able to nail this one down definitively. Has anyone run across something like this? Is it generally best practice to reserve the IP addresses of desk phones on a VLAN? Any insight would be appreciated. Thanks in advance! Rich
