Hello, I currently own 2 Cisco 3845's which are ip-ip GWs. However this company used to own 3 Cisco AS5400 on SS7 for VOIP traffic in Ecuador, Spain and Colombia, i can definitely get the job done, I have all show run's from those systems so its simple to copy paste the work. Not only that but i have several friends which are Cisco engineers if i have any questions i can get help from them, i also have access to cisco online. Im also asterisk knowledgeable. I speak English and Spanish. You pay after job is done, if i cant get it done in a timely manner i dont get paid.
