Resumen:
This work involves the implementation of a small Asterisk based PBX capable of accessing GSM network using
Chan Mobile module what allows using cell phones
from the IP telephony network connected to the Asterisk server that require establish communication to GSM
mobile device.
With the implementation of this project we efficiently administrate the
for business use by considering: the acquisition hardware cost, that calling between cells of a same mobile
operator is always cheaper, the control over the call’s length, hierarchy of access to output channels by us
using text messages (SMS) as a additional alternative to calls due to they are cheaper and their impact on the
server is less.
