IP dialing INTO SPA 112

[imfloridaguy]

I need to be able to dial INTO a SPA 112 via IP address, rather than a registered voip extension.  I can do this with Grandstream ATA's, but can't seem to do it with the SPA 112.

There is an article that talks about dialing between 2 different SPA 112's, and even between port 1 and 2 on a single ATA.

(attached as an image and found online here, item #3 https://www.cisco.com/c/en/us/support/docs/voice-unified-communications/spa9000-voice-system/108945-pqa-108945.html)

However, I need to be able to dial INTO the SPA 112 from non-Cisco phone and ring the connected phone on port 2.

Again, easy to do with a Grandstream ATA, but can't seem to figure it out for the Cisco.

The article says to dial 1002*IP_ADDRESS*5061# for port 2 (after having enabled it on the SPA).  Yet this doesn't work.

I'm using a Yealink T46G to dial and setting up a speed dial.  I've tried several variations on the above, such as 1002@IPAddress:5061 or 1002*IPAddress:5061 and a few others.

Any help would be appreciated.

The YeaLink SIP-T46G is a modern IP Business phone. I assume you have verified that you can make a direct unregistered IP call.

1002@IPAddress:5061 in a speed dial should work

IPAddress can be either a local network address or an external ip address. If it is an external ip address then you may get into router blocking problems because the call is not solicited. Blocking problems are solved by port forwarding.

I would try to verify that the sip INVITE command is physically received by the SPA112. The SPA has a logging function that may show the incoming sip detail. If you have a capability to capture the network traffic with WireShark it would be even better.

On the SPA112 Line 2 should have the following settings
Line Enabled
Sip Port 5061
UserID: 1002
Ans Call Without Reg: Yes
Make Call Without Reg: Yes (if you want to make outgoing calls)

If you are receiving a call over the external ip address you probably need NAT Mapping Enable: Yes

Thank you for your response.
Yes, I have all of the settings you have suggested set correctly. I would have expected 1002@IPAddress:5061 to work, but it did not.
I have had success with this same thing, from a Yealink phone, to a Grandstream ATA. I expected the Cisco could do the same, but no luck yet.
If anyone else has an idea, it would be greatly appreciated.
