I have Google Voice set up as SP1 and CallCentric set up as SP2 on my Obi100 via the ObiTalk web portal. "Google Voicemail Notification" is checked on SP1 and works correctly. Whenever I attempt to check "Voicemail Notification" on SP2, the check mark disappears as soon as I press the "save" button. Thus, I cannot receive any Message Waiting Indicator (MWI) on my phone for CallCentric's voicemail.
Does the Obi100 support MWI simultaneously on both SP1 and SP2 or does MWI only work on the primary line which would be SP1 in my case?
If it has any bearing at all on the matter, the phone I am using is a Panasonic cordless Model No. KX-TGA1018.
Thanks in advance for any and all help.
