Have you proved that using a dnslookup tool on the device?

 

Yes, using MXtool dns lookup on an EE network phone on 4G will not find the dns

 

Do the same on a three network and it will report all working fine, ISP etc etc

 

Thank you again for replies

Small update for those that are interested.

 

I installed a Qvis system for a client yesterday and they had a phone on EE.

 

i created the dyndns domain and port forwarded as usual and it worked fine, however this was the older style Explorer app qvis kit not the newer Super Live Plus. 

 

So, i think EE are only blocking a particular port that the newer DVR/NVR's are using maybe port 554?

i always change the default ports anyway. A lot of providers block 25, 80 443 etc. Is 554 default rtsp?

Ah ok, i have only changed ports when ive had multiple dvrs on one site.

 

Can you change the ports to anything? 

 

Yes 554 is the rtsp port from memory

Qvis version dont use superliveplus? That's a tvt machine that qvis have started to supply called viper , unless your saying there explorer version has been modified to work on superliveplus

 

Explorer is there new app , forgot what the old one was called which can no longer be downloaded even though electricians still sell what's left confuses them as box has old app on it

The quattro uses the Explorer and the Viper the Super Live Plus, both i buy through Qvis but not sure if it is actually theirs or just a rebrand.

 

Im phasing away from quattro and on to Viper now really but the Viper works over three ports where as the quattro just the one (34567)

Viper they is just the cheaper version that tvt make but better than there other brands imo , I don't buy it from them myself but know that versions they sell , all made by TVT including the domes bullets associated with the viper , all tvt products 

Six Wheeled Beast, can you enlighten me on the NAT loop back? quite a few jobs that i complete have the same issue where i have to create two user accounts, an internal IP one and a dynamic DNS one

NAT loopback is provided or can be enabled on some routers to allow a LAN address to access a server/port that is forwarded to your WAN.

Some consumer end routers may have a firmware upgrade that will enable it, like some Netgears.

Higher end stuff it may work OOTB or need to be setup or switched on manually.

Basically avoid cheap ISP provided routers.
