Now days, the switchport trunk encapsulation dot1q is not needed. It's default on the devices when you have a trunk. You only have to change it if you want to use ISL.

I don't think you need the "switchport mode access" command. Also, if you're using portfast, I would suggest enabling bpdu guard, just to be safe.

why the  switchport voice vlan 200  is not executed.

Are you using a Cisco phone and Cisco switch? Do you have CDP enabled on the Cisco switch? These are necessary to use this. Also, I believe that older switches don't support this, I would assume that if you can enter the command it would though. Please confirm you're using a Cisco phone and CDP is enabled.

using grandstream , please help me

If you're using Grandstream phones (haven't heard of them) my understanding is this will not work. I believe you'll need to force your phone to tag the traffic and then set up the access ports as now trunk ports. I believe for the Cisco switch to show both ports as an access port for two VLANs, you need to have a Cisco phone and CDP enabled. Then Cisco does its magic with CDP.
