Hello,
I am planning on deploying a CUBE SIP to SIP Trunk to an ITSP in the near future. I have created a sample config on my CUBE device, and I was hoping that someone with experience implementing this sort of thing might be able to take a look at my config and let me know if I am missing anything. I would greatly appreciate any feedback. Please see config attached to this post.
Thanks!

Staurt,
Here are a few thoughts for you..
1.
conf t
voice service voip
sip
early-offer forced
header-passing
error-passthru
2. Your Bind command is applied to your loopback interface..The question is, is the ip address on this loopback routable to your ITSP. If your ITSP cant connect to this IP, then there will be issues
3. Is there any reason why your preffered dtmf is sip-kpml...even if you want to use this, it should be a backup..so i suggest you change your dial-peers to have rtp-nte as primary dtmf
dial-peer voice 101 voip
destination-pattern 818[489]......$
voice-class codec 1
session protocol sipv2
session target ipv4:X.X.X.A
incoming called-number .
dtmf-relay rtp-nte sip-kpml
4. Plan for Faxes. If you have faxes in your deployment, ensure that if your ITSP does not support T.38 you configure appriopraite dial-peers to use G711 for fax calls....
Just my 2 cents

Thank you! I will definitely look into modifying my config according to your suggestions, and I will update this thread once I go live on the SIP trunk.

Did you even end up going live? I have a 2821 at home with IOS 15 and am wanting to use it for terminating a ITSP session for use in my home environment.
