Asterisk and MFCR2 for Mexico

Hi everybody;

I have a problem, i work with a Sangoma Card (A101) and Trixbox, i installed the libraries for MFCR2 (spandsp, libunicall, libmfcr2, libsupertone) and all run ok, but when i want to connect to asterisk with asterisk -r command, i got a error:

Unable to connect to remote asterisk (does /var/run/asterisk.ctl exist?)

I see my this path and this file is there, What can i do for connect to asterisk and can continue with the configuration for MFCR2?
