Actually we have alcatel-lucent PABX system in our organization. we have 430 IP Phone in the head office and around 400 IP phone in the branch office. we configure cisco 2800 router for SIP Trunk. now the problem is that our SIP trunk router which is cisco 2800 router is getting stuck every two or three days but when i restart the router its start working. now i need solution, that this cisco router is able to handle traffic for the above setup or not.
