I'm on Vodafone's UFB using my own router connected directly to the ONT. I have the SIP settings copied from the Vodafone supplied router, got my username and password emailed to me from Vodafone, but I'm struggling to get the phone set up.

The SPA112 is connected to the router, I have entered the proxy, my username and password in the appropriate boxes but it fails to register - no tone at all on the phone, just completely dead.

Clearly I'm missing something somewhere, can anyone give me a hand please!

There are potentially any number of reasons why it won't work, including the fact Vodafone won't allow any devices other than their own hardware to connect. Anybody know if this is the case?

SIP isn't quite a simple as having 3 settings.

Ok I thought it was but clearly I'm wrong.

I was using the Huawei router as an ATA but when people called the landline they could hear you, but on our end it was completely silent. Making calls from the phone worked fine. Vodafone said it was all working fine, I couldn't see anything on my router that might have been affecting incoming calls so got my hands on the Cisco SPA112 but now it's even more confusing, so I'm not sure how to get it working.

Are the SIP ports (5060) open on your router?

Port your number to an independent VOIP provider like 2talk. Screw device restrictions. Gain features.

Oh, and 2talk do automated provisioning of SPA112 devices. I know it works well, because I use it.

They are.

I don't get it. Why can I call from the landline and it works perfectly, but when people call the landline why can they hear me but all I hear is dead silence???

Because NAT is in the way.

One-way speech is almost always NAT/firewall issues - could also be codec.

Remove any port forwards you have in your router but make sure you have a firewall rule to allow 5060 in to the network.

Then on your SPA bring down the registration time to maybe 360 and set it to send SIP OPTIONS every 120-180. That should be enough to cure any NAT issues.

On your 2Talk settings go to 'Voice quality & networking' and disable G729, enable G711a & G722 and set it to "Prefer excellent quality calls".
