[Asterisk-Users] No caller ID, straight to voicemail

[Michael Delage]

Hi,

I am having a problem with inbound calls (from a SIP VIOP provider).  
When caller ID information is not available, the calls go straight to 
voicemail.  We are using a mix of either Sipura 841 phones or SPAs.

When the call is passed to the phone/SPA, Asterisk reports "Got SIP 
Response 406 "Not Acceptable" back from..."

I have searched a while now and can't seem to find any reference to the 
cause of this error.  Does anyone know what could be causing this?  Is 
it an Asterisk issue or a setting on the SPA?

Thanks,

Michael
