I am a lawyer in Lower Hutt and I have no programming experience.

Towards the end of 2010 my wife decided to set up a hairdressing salon in High Street, Lower Hutt.

My wife has no knowledge of things technical and like a lot of people, computer technology and my wife are a poor combination at best.

I decided that as the telephony world would ultimately be voip, I would a naked DSL connection which would provide for eftpos and telephone service.

I already had a voip connection at home with Kiwilink which connected through Saturn cable and a Linksys pap2 adapter to a portable analogue phone.

I have been more than happy with the service of Kiwilink in regard to this connection.

I purchased a D-Link DSL-2730B ethernet router from Harvey Normans, and two Yealink SIP-T26P phones from Nicegear in Timaru.

I wish to say at this point that I am less than happy with the after sales service provided by Nicegear. The quality of service has been next to non existent, and that company has walked away from the configuration issue which I believe is the route cause of my problems with the phones.

The phones arrived late November or early December prior to the opening of the salon so I set up one phone in my office which is upstairs from the salon. My ISP in the office is Woosh.

The only information which I was given by Kiwilink was the username, password, and sip setting. In my previous dealing with Kiwilink they had mentioned the stun setting.

After I set up the phone I found that when I was on a call the voice at the other end was breaking up and I could hardly hear the other person.

I contact Nicegear by phone and was told that this problem was probably an ISP issue, or maybe codecs, and as Hadley Rich was not familiar with Kiwilink he could not help me ( ie was not interested in helping).

I installed one phone in the salon, but my wife experienced the same problem, although the person on the other end could hear perfectly well.

I went back to Hadley Rich but was told that the problem was either the fault of the ISP or was a configuration issue, but he did not make any suggestions as to the configuration setup. Kiwilink was no more helpful because I had not purchased the phones from them. They would have supplied Linksys phones.

So I brought the Linksys pap2 adapter and phone form home and connected this to the router. This phone worked perfectly.

I should say that the only devices connected to the router are the phone and the eftpos machine.

When I first set up the phone I did not put an entry into the Outbound proxy server field.

I did though put Stun into the NAT Traversal field, with stun.kiwilink.co.nz as the reference.

After taking up a lot of time searching on the internet I decided to enter sip.kiwilink.co.nz into the Outbound proxy Server field.

My wife said that she could hear the voice on the other end perfectly as a result of this change, but when the phone rang and she went to answer it, it cut out.

I suspect that I now may have a conflict between the various port assignments as the sip Port, the Outbound Proxy Server Port and the backup Outbound Proxy Server port all use port 5060.

When I tried changing the Outbound proxy server port to 5083 I could not get the phone to register.

Can someone help me with the configuration of these phones? And do I need an entry in the Backup outbound proxy server port field, and what about transport? Is UDP correct?

I can email to any reader the various pages from the setup menu in tiff format.
