[asterisk-r2] specific config for Angola Telecom

[Gomespereira]

Hello to all
Did someone tried to configure R2 to work with Angola Telecom?
I dont know what to put as
mfcr2_variant


Also, asterisk is saying:
WARNING[11092]: chan_dahdi.c: 13148 process_dahdi: Ignoring signaling
WARNING[11092]: chan_dahdi.c: 13148 process_dahdi: Ignoring switchtype

WARNING[11092]: chan_dahdi.c: 13148 process_dahdi: Ignoring mfcr2_category


What could be happenning?
Thanks
