Again thank you for your suggestions.
I deleted the number from my phonebook and had the same result. I put them back in and had the same result.
In
VOIP.MS I can see the call logs and I can see they are getting through but are going directly to voicemail.
I went through all the setting again looking for that particular number. I do not use an special setting, sub accounts, forwarding etc. I never went into setting in OBI202 since I originally set it up. The only reason I go into
VOIP.MS is to add people to phonebook and to check my balance.
If it was everyone that went to voicemail I can understand but not just one number. It is the person I contact the most which makes this worse.
My provider is out of suggestions.
