TDM switch E1 and Polycom RMX1500

Hi guys,

i need to passthru 4 channel of a Telco PRI (15 bi-directional channels). I've two E1 dual-port (Cisco 2811 with 72 DSP PVDM) card and this is the configuration of Serial interfaces:

there are the dial-peers:

port 0/0/0:15

!

when I call 065678998, the call is routed on voice port 0/3/0:15 (where RMX is attached with E1 cross-cable) but the call is terminated by the other endpoint (RMX) and sent to the voip dial-peer (that has T parameter).. i'm still investigating if it's an issue of the RMX, because on the q931 debug the call seems terminated in a normal way

I can also not make outbound call from the RMX via E1. Doing a debug of dial-peer when the outbound call is placed, there is not match

I get a B-channel up on the Serial0/3/0:15 (coming from RMX), but the router doesn't "route" the call to the other voice-card (Serial0/0/0:15 Telco PRI)

How to solve?

Many thanks!
