[cisco-voip] My first SIP trunk

Fri Jul 21 19:37:27 EDT 2006

I have done the fixup protocol command. I ran nmap port scan against my
CCM, and port 5060 is not open. Am I missing something? Do I need to
tell ccm to open the port? I just made the sip trunk from the web
interface...

Here are the new logs:

I believe there is a fixup protocol SIP 5060 is that in your config on
the pix?  What version of FOS is on your pix?

Subject: [cisco-voip] My first SIP trunk

I have decided to start playing around with SIP trunks, as my company
needs more and more varied area code terminations (we have 4 PRI's and
counting). I signed up for a demo with bandwidth.com and all they gave
me is an ip address and udp port 5060. It looks like im on my own after
that....except for my favorite mailing list ;)

Here are the steps I have followed so far:

I created a sip trunk in CCM: http://www.cimgroup.com/temp/sip_setup.jpg

I created a route pattern to use that sip trunk.
http://www.cimgroup.com/temp/route_setup.jpg

I made the proper pokes in my pix, to allow traffic from their SIP
server, to my ccm.

Then, I tried to dial 713239438822  from my IP phone -- no dice.

So, I run a debug sip on my PIX, and I try to make the outbound call
from CCM again, I am getting the following:

5175: SIP::INVITE received from inside:10.96.3.11/5060 to

IF I try to call the SIP number bandwidth.com gave me (from my
cellphone), I get the following:

Is this a problem with my PIX configuration, or my SIP trunk
configuration? Anyone have some good SIP documentation?

Thanks,

Avidan
