What device are you using - followed what you had set using a YEALINK T33 and no calls received, outbound works fine.

Nick

Any chance you can share your Yealink config?

Now got this working on a Yealink T33 - as reported by others only a single device seems to receive calls - multiple cannot. For those wondering - removing the 'proxy' is what has solved this for me despite what the documentation says!

Hi all. VOIP noob here - pls be gentle.

Also very pleased I found this thread as I've been banging my head against the wall for a couple of days on this.
I recently bought a Yealink T46U from Amazon, supposedly 'new'. I was under the niaive impression that I could just plug a SIP phone into an eithernet port on my router and use it woth Zen DV. But no.....

Plugged it in, and went to setup the phone via its web interface to find out that the default uname/pword didn't work. Turned out the phone is (quite likely) a refurb as it was looking up and overriding uname and pword from Yealink's RPS server. After a bit of back and forth with Yealink support, got the MAC address deleted from their RPS so now I can configure it.

I called Zen and got my uname (landline number, as discussed above) and pword. Note: the pword is no longer available on the portal, both old and new versions.

So now I have access to the settings page on the phone. However the phone is still not registering.
The only params I have entered are the uname, pword, and the server name (voip.zen.co.uk). All other params are default (port is already set to 5060). I've left the label, display, and register name blank, as advised earlier in the thread)

I'm almost at the stage where I'm just going to repackage the phone and return it to Amazon as defective (as it's likely a refurb), but this is my last ditch attempt to try and configure it. As others have suggested, i'm not keen on moving to a new SIP provider as I don't want the expense and hassle.

Can anyone tell me whether there are any other settings needed to be changed for the phone to register?

Hi

Have you opened the firewall ports for voip?

Nick

Hi - I haven't - the SIP phone has a ping function and I can ping the zen voip server from the phone. I'm no tech expert but I interpreted that to mean there's no firewall issue getting in the way of the connection.
Shout if that's not correct!
If not - the firewall settings should be in the Frtizbox. I did have a quick look but there's no obvious place in the Fritzbox config screens to turn a firewall off.

I've spoken to zen a couple of times; I want them to tell me what their server logs are saying about why they're rejecting my registration request.
If I can't do this with my Zen services, the next step will be to request an unbundling of my VOIP and my broadband (which I am happy with) as there are plenty of other SIP providers who can help here.

Hi,

If you look at the Zen VOIP SIP setup guide it tells you what ports need to be open, worth checking you have the inbound ports open too, not just outbound. Not sure where that is in Fritz box as I don’t use mine.

Dear All,

My Zen Broadband & Digital Voice service commenced 2 Jun 23 and I was able to get Digital Voice working with the supplied FRITZ!Box 7530. Due to various limitations is FRITZ!OS, I migrated to OpenWRT and bought a Grandstream HT801 to support SIP Digital Voice.

I wasn't able to get the HT801 working, even after lengthy interaction with Zen Customer Support (excellent staff, let down by counter-productive management attitude). So I bought a Siemens Gigaset GO Box 100 (same hardware as N300A). With quite some fiddling, I was able to get this to work.

A month later, I tried the HT801 again and it worked. Have asked Customer Support but still don't know why. The only feature that I haven't yet got working on the HT801 is Caller Line ID.

I have also tried the excellent MizuDroid SIP app on my Google Pixel Android phone. It works at home, but not out of the house, backing up @rikur in his "traditional SIP" hypothesis.

Happy to share my detialed config notes with anyone. I have invested quite some time in this.

Found this thread. I have the Frit!Box working behind my router but cannot get a Cisco ATA192 to work. It's soooo complicated - so many config options, really regretting my decision to buy. Anyway at least it has decent diagnostics. I have tried a bunch of things and got it to register a few times but no longer and no dial tone, the outbound log shows this:


Feb 18 19:27:10 CISCO-PHONE local1.debug vsock: REGISTER sip:voip2.zen.co.uk SIP/2.0 Via: SIP/2.0/UDP 192.168.1.134:5060;branch=z9hG4bK-4eb0e6f3 From: \"014********\" ;tag=e212926f3caab3a3o0 To: \"014********\" Call-ID: [email protected] CSeq: 1688 REGISTER Max-Forwards: 70 Contact: \"014********\" ;expires=3600 User-Agent: 014******** P-Station-Name: ;mac=14a2a0aabf6c; display=\"\"; sn=FCH25492AHD Content-Length: 0 Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER Supported: replaces, sdp-anat

Really my question is what should I be aiming for with this string? Anyone got the registration URL for the Fritz!Box? Just about to give up. Anyone got an ATA192 working with Zen?

Have you asked Zen?
