Is anyone using 2talk successfully on skinny broadband, either with the voice port on the skinny modem, or with an ATA? And if you are, I'd love to hear the details of your setup and what the call quality is like.

I can't get it to work reliably - changed ports, udp / tcp, changed Nat settings, stun doesn't help

Initially you can make outgoing calls but that comes and goes - inbound almost never works.

Double NAT and VoIP don't play together nicely.

The supplied router (a Huawei B315s?) has a voice port on the back ... is it possible to get that working?  Then you'd skip a layer of NAT.

My understanding is no

It's still a CG-NAT connection to the router though - which is really just double NAT. With an ATA behind you'd have triple NAT!

Did you auto provision the ATA? I had an SPA112 working fine for several weeks whilst testing on Skinny.




Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

2talk works fine with CGNAT as long as you set your device to use their sip proxy.

So.  Set this up today. At 10am, calls to the newly ported phone number made the phone ring.  Went to buy an extension cable; came back and the phone doesn't ring anymore.

 

Outgoing calls are fine.

 

I'm using an old Sipura SPA1001 but have exactly the same problem with the PAP2T I borrowed from work.

 

Any suggestions?  I have a ticket open with 2talk.

Probably lack of TCP is your issue.

Try port no 50600 instead of usual 5060 or reduce registration time to 180.

One way i have got VoIP working on a skinny BB connection is to have a second router that creates a VPN to a server that give it a non-Nat'ed address and send all VoIP traffic over that connection. i have set this up for a mate who wanted a VoIP PBX but the DSL would not support multiple calls at a time. This Solution has not missed a beat since it was installed and at times has up to 5-6 calls at once

 

Hardware/Setup i used is as follows Mikrotik RB2011 > Skinny Router > Internet > VPN Server > Internet With Static IP

 

RB2011 has a static IP on interface facing Skinny Router with no Default Route. It has a static route to the VPN Server via the Skinny Router. Once the VPN stands up a Default route is added and all traffic flows via VPN (only VoIP in this case) I supply a Static Non Nat'ed Public IP to the VPN connection and all is good. Any time skinny changes the CGNAT IP the vpn re-connects and keeps going

 

 

 

I Know it is a long winded way of doing it but it works and the customer is happy.

 

 

 

The Phone port on the back of the Router is not an ATA but uses the Voice Channel of the Mobile connection. it is the number that is assigned to the SIM so long as Voice is enabled but my understanding is skinny don't provision voice on the BB SIMs

Cut registration down to 60s; noticed a lot of registrations were failing.

 

Will try using tls.2talk.co.nz (2talk's suggestion) today.

 

Have provisioned one of my old Dragionos with OpenWRT to create an L2TP VPN back to my RB2011 at home.  Will try this if tls.2talk.co.nz doesn't work.  I would have used a Mikrotik but I don't have any spare :-(

Couldn't get OpenWRT L2TP (or PPTP!) to connect back to the Mikrotik at home.

 

Have managed it with OpenWRTs running OpenVPN at both ends.  Call quality is fine.  Latency to 2Talk is ~115ms.

 

(edit) By comparison, latency to 2talk without the VPN is about 80ms.  The VPN means sending everything to Auckland and back again a few more times than would be ideal.

On windows using zoiper client i was also getting same time outs(using spark adsl so no double nat).

 

Though same was working fine on my csipsimple android softfone. 

 

Next added another sip account with voipstunt and zoiper asked to update some settings. clicked yes and voila both voipstunt and 2talk are getting registered now. 

 

Its now using stun enabled with address stun.zoiper.com and port 3478 with refresh period of 30secs.
