Do you have separate CCM clusters at each site or 1 cluster spread across 2 sites? The one-way audio and Site 2 to Site 1 problems could be ip routing issues. Make sure you have a route from Site 2 to Site 1. You can integrate analog phones by using ATAs (2 ports) or a product like the VG248 (48 ports).
One possibility is to leave the analog phones connected to the EPBX and use a trunk (E&M, QSIG) to connect the PBX to your router. The exact configuration is dependent on the type of PBX, type of trunk, etc. This would allow you to call from analog to IP phones, use extension dialing, toll-bypass, etc.
Your current bandwidth is very likely not going to handle the number of phones and potential calls in your environment. If you are going to run voice between these locations with 1000+ phones, I would reccomend doing some capacity planning and increasing your bandwidth. Would you mind to send screenshots of the intercluster trunk configurations in CallManager?
Intially for testing Voip setup, I would stop link access to data servers temporarly.
I dont want to join 1000+ phones now, I just want to test with only 2 cisco phones at one side and 80 cisco phones(7960) at other side,no more analog story now.Please find the attachment of inter-cluster-trunk screen shot for both sites.
Check the codec being used. Initiate a call from Site1 to Site2. Press the "i" button twice on both phones. Look for the codec being used. Also, look at the following note:
Note If this non-gatekeeper-controlled intercluster trunk accesses the device pool of a remote non-gatekeeper-controlled intercluster trunk and that device pool has a second Cisco CallManager node, you must enter the second remote Cisco CallManager IP address/host name in this field.
I saw your config in your post in the General forum. These commands:
h323-gateway voip interface
h323-gateway voip id SITE1 ipaddr 10.45.100.250 1718
indicate the use of a gatekeeper when in fact you are not using a gatekeeper. Remove these commands from both routers and verify that you have a route pattern configured to hit the intercluster trunk for intersite calls.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
