I am on EE network in UK, and use www.voipfone.co.uk VoIP service
Zoiper connects and registers on WiFi but whenever i switch over to mobile data, it wont connect or register.
ive been trying to find solution to this, but to no avail
Please check your stun settings, probably blocked by your provider, maybe you can select to use higher ports? Ofter the used APN on your mobile are restricted for web applications, maybe you can check if another APN has no restrictions.
Ok, i have looked at my STUN settings, do i turn on STUN?
i have two voip providers, SIPGATE and VOIPFONE, on mobile data, SIPGATE connects ok and works very well whilst VOIPFONE wont connect.
Both accounts work very well on WiFi
Assuming that you have a single account at voipphone:
SIP Server/Proxy/Registrar = sip.voipfone.net
Stun can help indeed, but does voipfone supports stun? Otherwise configure the STUN server of zoiper ( stun.zoiper.com )
