Hi ...
I have the following telephony structure:
pbx ----- MC3810 -----------------------------------------MC3810 -----pbx
where an E1 ISDN with Q.Sig trunk between the pbx and the router. Between the routers we have WAN Frame Relay. The pbx's are two Philips Soho IS3030.
The two pbx exchange signaling through one specific channel with the "clear-channel" codec.
In the structure above, it the voice works perfectly, but we have to change this structure because it's growing.
We have to change one side MC3810 for an AS5300, with two E1, but when we put the 5300, the "clear-channel" channel doesn't work. showing the following messages.

The 5300 configuration is listed down and is exactly equal to the 3810 configuration, only reversing the dial-peer.
