Try a softphone and see if it works correctly, that would at least allow you to understand what direction the issue is coming from. Do calls into the auto attendant get answered okay, and transferred?
If the softphone doesn't work, check with your ITSP and see if they accept Invites without SDP. I've seen that as an issue with ITSP. They are required to. If the Softphone does work, I think you may have an issue with the Grandstream phone itself. 3cx has a nice free softphone you can download without registration.

The provider is IIS Group. You are correct on hold or transfers don't work for inbound calls. Is this port forwarding configuration enough or do I need to have the provider send requests to port 5080?

Does this mean transfers don't work? If so check or ask the provider to send invites to port 5080. On Feb 7, 2012 1:54 PM, "Mark Roseboom" <[email protected]> wrote: Using sipXecs 4.4. Inbound and outbound calls work with my ITSP. Placing a call on hold works when calling any internal extension. On hold also works when making an outbound call through SIP trunk. However when an inbound call comes in, and its placed on hold, the call is dropped. Thinking it must be a NAT / firewall issue. Not sure what other diagnostics to give, please let me know. Thanks.
