Hello everybody.
I have a network with two 2921 routers in it (K22.R1 and K22.R2), each router runs OSPF process with all networks that this router belongs to ncluding voice network), each have it's own CME (9.1), first CME works in VLAN 2 (10.10.22.1), second in VLAN 3 (10.20.22.1). IP phones inside each CME works fine, calls within each router are placed, but when phones from R1 call to R2 or vice versa, i see on the phone "unknown number", though all dial-peers are in place, and in debug I see that, for example, call from R1 is reaching R2, R2 matches incoming dial-peer, but it seems cannot find dial-peer for local registered phone.
I've modelled my network in PT (see in attached file), and in model it works fine, calls are reaching phones on remote router.
Here's portions of real configs:

On the routers i see that all dial-peers are up, calls are reaching remote router, but it cannot find dial-peer and phone shows "Unknown Number".

I've tried debugging ccapi, but i didn't see no problem in there. Where else can i look to find the problem?
Please help.
