Need Help with Routing Tables

[renet123]

I have a 2 site network that is attached with a point to point T1 hooked to a Mux branded 'AFC' (for a telephone system) at each end. I have an additional SonicWall router that both sides are using to browse the internet with.
I have called the sites Sites A & B, and Site A has the SonicWall

Right now Site A cannot ping or connect to Site B - additional details in the code snippet.
I have tried to do the text network diagram.

I am sure there is a problem with my routing tables, or i am missing one. SonicWall support team helped me with the routing on the sonicwall - but im pretty sure the problem is on the mux.

I have tested many combinations:
I have ping tested both ways.
I have tried to test by making the lan devices on site A have a gateway of 192.168.1.253 to ping things on site B - just to see if the routing was OK with no luck.

Please let me know what routing tables to add.. change .. or delete.. Im thoroughly Confused.
