Phone model Samsung Galaxy S8+, Android - OS V 8.0.0 Security Patch November 2018
3CX ver 15.5.15502.6
Android Client V 15.5.346.651
Hi
I setup unsupported SIP trunk from VOIP Yonder the other day, its a PAYG with no setup cherge and ideal for where I am just now in testing phase (Ive been testing for about a year now !) worked fine with 01/02/03 numbers but gave above error when phoning mobiles, I added some credit to the account incase that had anything to do with it but at the time it didnt, left problem for later. Some hours after when I tried again it was working fine, even tested sending calls to mobile with wifi switched off, just on Vodafone data, I even tried it outside the house off wifi, all worked fine, today back to getting the above error message.
Works fine on an SNOM 360 handset in office and a DECT otherwise I would have suspected SIP provider, anyone got any clues?
