[asterisk-r2] Problems with Telco

[Victor Villarreal]

Hi Thiago,

I never have this issue here, in Argentina. But you can try enable CRC4,
maybe your provider need this to work.

Other setting i have been to tweak every time, with diferent telco provider
are metering_pulse and mfback timeouts.

Hope this help. Please, submit if you success.
