Switchport mode general

Let me preface this with the following... Basically, we have a MSP that has been brought in to tell the C level everything we already told them and now we are rushing through initiatives that should have been done a long time ago.

My current issue is with network upgrades and the MSP keeps setting or leaving some ports unconfigured and set to mode general on the new switches. In doing so, we have run into issues where devices cannot communicate on our network. In order to resolve this, we either have to set one of the following...

switchport general allowed vlan add ###,### untagged

or

switchport mode trunk

I'm not even remotely an expert, so I am assuming because we have Cisco VOIP phones everywhere, this is why we need trunk on most ports. However, in order to get a Starleaf video conference system and a clickshare and a PC without phone back online I also had to set their ports to trunk mode as well, since general wasn't working.

So I'm wondering if anyone else actually uses mode general or is this some weird problem with our network?
