I am going to ask my questions and then follow with my scenario:

I have a trunk office 1 to office 2 and a trunk from office 1 to office 3 that initially was up, but now is down. I can't ping the PBX's from the PBX's, but I can ping both PBX's from any desktop. I have no issue with the trunk from office 2 to office 3. The set up's are almost identical.

Office 1 PBX (R11)
IP: 172.30.72.202
Gateway: 172.30.72.1
Subnet: 255.255.252.0

Office 2 PBX (R11)
IP: 172.30.122.201
Geteway: 172.30.122.1
Subnet: 255.255.255.0

Office 3 PBX (M2.0)
IP: 172.30.68.106
Gateway: 172.30.68.1
Subnet: 255.255.254.0

Office 1 Route to Office 3
Destination Node: PBX 3 node-name
Network Bits: 24 (no matter what I do, it goes to 24 bits)
Subnet: 255.255.254.0
Gateway: PBX 1 node-name
Board: CLAN
Metric: 1

From PBX 3:
I can ping office 3 router interface
I can ping office 1 router interface
I can ping PBX 1 gateway
I cannot ping PBX 1 CLAN

From PBX 1:
I can ping office 1 router interface
I try and ping office 3, it says there is multiple routes

From PBX 3:
I can ping office 3 router interface
I can ping office 1 router interface
I can ping PBX 1 gateway
I cannot ping PBX 1 CLAN

Office 1 PBX (R11)
IP: 172.30.72.202
Gateway: 172.30.72.1
Subnet: 255.255.252.0

Is the PBX 1 Gateway, the IP of the router 1 interface? If so then being able to ping it will work without a route being setup in the Router. In order to ping any device beyond that interface you will have to set a route.

The addresses you are using are not routable across interfaces without being statically set. They are private IP address ranges which are dropped by the router by default. This sounds like a routing problem, examine the route tables of the routers. I think for myself or anyone else to be of help you would need to provide more info.
