Asterisk error with r2d

Hi,

I need help for this problem

I need my asterisk configuration, follow config.

I change my config for Asterisk use R2D but I have many problems.
I think my config is ok.

And once that error is below I believe this message is the cause of the problem, I’d love to find a solution

ThisMay 7 21:39:32] NOTICE[22109]: chan_dahdi.c:4191 dahdi_r2_on_line_blocked: Far end blocked on chan 12Means that your Telco blocked the channel. Check if you need the CRC4 and also test the cable.

Thanks, I will check.

I came in contact with the operator and she told me that checking the channels that they see the error says that the asterisk that is blocking the channels, does that make sense?

hi, follow another error

MFC/R2 call offered on chan 10. ANI = 1820, DNIS = 3553, Category = National Subscriber
[May 14 14:42:20] NOTICE[22108]: chan_dahdi.c:4007 dahdi_r2_on_call_offered: MFC/R2 call on channel 10 requested non-existent extension ‘3553’ in context ‘dahdi-in’. Rejecting call.

Asterisk reject calls my asterisk version is 10.7.1

Do you have an extension handler for 3553 in your dahdi-in context in your dialplan?

This error happened during a simulation that received the phone connection 35530000, but perhaps this error can guide you better
