I am planning to configure SIP. I have CCM7 and Unity 7.0 and at&t is my local PRI provider.

I am using 2811 only as my voice gateway so I guess will need to configure accordingly. Thanks!

Ok so you already have the gateway configured in CCM 7.0 ?  This should get you going with the router.

Do you have a sip trunk set up in CCM ?


sip-server  dns:FQDN or IP This will be the IP of the dns or the fully qualified domain name

ip domain-name xxxxxxx this is your company domain

ip address xxxxxxxxxxx (Will this be my 2811 router IP?) yes

ip name-server  xxxxxx (Will this be my DNS server name?) yes

Bind control source-interface xxxxxx this is your ethernet int ip address
Bind media source-interface xxxxxxx this is your ethernet int ip address

No. I haven't setup SIP trunk in the CCM yet. This is for my new site, I haven't configured the Call Managers at this moment. At this moment I'm making sure I have all the correct configuration ready before deploying it next week.
