I am struggling to register on this device; Grandstream HT701. I have entered the SIP details but still failed to register.
I am on Vumatel with Cool Ideas, using a TP-Link WR840N router
We had some Afrihost users report a few connection hurdles - Afrihost responded and noted that in some cases you need to specify the port in the SIP server.
Where you have entered the SIP server please enter it as seen here sip1.freshphone.co.za:5060 and revert back if successful.
I made the suggested changes and succeeded.
