SIP trunking with a Cisco 3825 integrated services router
Posted on 2013-10-29
We are trying to implement SIP trunking into our Interactive Intelligence system and I was hoping to use my Cisco 3825 integrated services router to perform this function. I read that it is possible.
I do not know what I am doing at all with SIP, but I do have my CCNA from 2002 (ok well it is expired).
My environment: Time Warner fiber @ 50m up/down burstable
Cisco DMZ switch (nothing special)
Client gateway: Untangle
1) What are the high level DMZ/router requirements as far as QoS?
2) What are my options on the IOS version and what do they afford me?
3) What physical modules does my 3825 need to have to perform all of this?
I am trying to do this on a relative budget, which is the whole reason we're trying to go SIP. Your wisdom would be appreciated. I am expected to start testing this circuit by next Friday. (It is October 29, 2013 today)
