clear-channel codec in AS5300

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.

The AS5300 is with 12.2(11)T2 IOS IP-Plus, VCWare Version 10.26a, DSPWare Version 4.0.26a (C542). Everything aparently OK.

Does anybody knows what is hapenning ? Any help is wellcome.

Re: clear-channel codec in AS5300

I guess the problem is not with clear-channel codec. The problem is with Qsig digit forwarding. I guess this is not supported in AS5300 yet, (As per the feature navigator).

dial-peer voice 1790 pots

destination-pattern 1790

port 2:D

forward-digits all <---------Not supported yet on AS5300. Maybe this is the culprit
