The configuration that I am going to say was not done by me, the only think I did was to create the IPSec VPN between both Sites, and that goes up.
The IPSec VPN is done in the ISP Router in both sites (Watchguard and PepWave)
The problem is the following.
Site A can ping Site B Cisco Router and all his interfaces. Then the Cisco Router in Site B is connected to a Cisco Switch 2900 Series (trunk mode in the switch), the problem is that I cannot ping any device that is under the Cisco Switch (included the switch which has the IP 10.0.1.10 has you will see), been going around for days and have not found the correct config.
Site A works fines and I will not show any config because is connected to other Sites and working
Site B has the following:

Cisco Router config (works has a call manager too):

interface GigabitEthernet0/0.1

Please let me know how to make Site A access as well Site B switch and the devices connected to it.
 
You don't show any of the VPN configuration. This could be caused by access list issues, routing issues, etc. I think a full config (remove keys/passwords/IPs as needed) from both sites would help allot.

Except for the NAT, which you don't show a full configuration for, everything looks fine. Can you ping from 10.0.1.1 to 10.0.1.10?

problem is fixed thank you. The problem was in the routing of the ISP Router that has the IPsec VPN, once the routed was created manually the problem was fixed.
