Local Site can Call Remote Site but Remote Site Cannot Call Local Site

I have configured local and remote sites between CCM and CME

The local site uses call manager with mgcp gateway to ISDN PRI

The remote site has CME configured and it is connected to Local Site via LAN (Will eventually be fiber WAN).

I have configured the trunk and dial plan on local site CCM.

I have added an H323 Gateway on local site CCM and Remote CME

All of the local phones are able to call the remote CME extensions with no problems.

None of the remote site CME phones are able to call the Local site.

When dialing the extension on the Local CCM from the remote CME, the Remote phones all get a busy signal.

The current dialing Pattern should allow for an initial 6 and then a 4 digit extension

Here is the config on the remote CME site router :
