I've recently got a Yealink W52P with 3 handsets and 4 VOIP lines running to them (1 handset runs 2 lines) and have connected up with 2talk using their cloud PABX system.

I'm having a problem with the Yealink maintaining its connection to 2talk - I wake up every morning and at least 2 of the lines connections will be down and when I check on the Yealink setup page it says "Registration Failed". It doesn't appear to be re-trying. And I can't make or receive calls on those lines. Which is just awesome, exactly what I was hoping for. :| When I try to re-register the lines, it often just hangs, or comes back as "Unknown" for the status of the registration.

Has anyone successfully got one of these phones to work with 2talk?

Has anyone got ANY phone to successfully stay connected to 2talk? (ie. is it a 2talk problem, not a Yealink problem).

Can anyone provide your settings so I can set mine up exactly the same?

Any help would be much appreciated. :(

What is your network setup and brand/model of router? Do you have double NAT and/or a SIG APG enabled?

DrayTek Vigor 2850Vn with VDSL (Snap) and backup ADSL2+ (Telecom).
Ethernet from the Vigor to the Yealink and DHCP.

Re: double NAT and/or a SIG APG enabled? - I'm not sure on that one!? :)

There's nothing enabled under the NAT section in the DrayTek admin. And I can't find any mention of SIG APG anywhere.

FYI - my softphone client just registered fine using the one number XXXXX-1 feature, but the Yealink still can't register. I just restarted the Yealink base (again) and now one connection that couldn't register has, and another connection that was registered now can't... it's never ending.

Nope can't find SIP ALG anywhere either. I'm not using any of the DrayTek's VoIP setup at all. The Yealink is just using the DHCP internet connection and registering directly to 2talk. No settings checked or otherwise under the VoIP section of the DrayTek. (see my edited post above re. the softphone connection).

Have these got hardware NAT? I had wicked troubled with a 2130 until I disabled the hardware NAT.

Maybe add a firewall rule to allow the 2Talk subnet (27.111.14.0/24) to go anywhere on your network too.

It might be like the Cisco SRP series where you have to actually disable the ATA otherwise it grabs all the 5060 traffic.

The other thing to check could be your registration interval. Maybe change it down to 360 or even 180 and see if it makes a difference.

Register 1 handset at a time.
Sounds a bit like you have the old now its registered now it isnt goin on.
The yealink may not like the - in the number string to register more than one device to the same number?
I want these for a client also using 2talk so keen to see how you get on with them.
They support 4 simultaneous calls so a good option for cordless office.
