<p>Hi Thiago,</p>
<p>I never have this issue here, in Argentina. But you can try enable CRC4, maybe your provider need this to work.</p>
<p>Other setting i have been to tweak every time, with diferent telco provider are metering_pulse and mfback timeouts.</p>
<p>Hope this help. Please, submit if you success.</p>

I have a big problem in a Asterisk connected with Brazilian Telco (EMBRATEL).<br>

Every received call, I have the same error:<br>
