After power lost

Hy, after i lost my power i get this message on my asterisk. I can’t call over GSM Gateways. Please help me on this message, what i must to do???

[Aug 21 15:11:36] WARNING[3207]: app_dial.c:1183 dial_exec_full: Unable to create channel of type ‘mISDN’ (cause 66 - Channel not implemented)

Seems misdn was not started automatically at boot, so try start it manually with

/etc/init.d/misdn-init start

and then reload asterisk.

You should start it automatically at boot, how to do depends on the linux distro you’re using.

Cheers.
