How to get Siri to dial my contact called "voicemail"? I have a contact in my iPhone called "voicemail" that dials my company voicemail service. If I ask Siri to "call voicemail" it just says "you have no new voicemails" as it's trying to check the mobile network's voicemail service (even though I've changed the voicemail shortcut in the Phone app to dial said contact). 

I'm sure I've managed to get it to call the voicemail contact in the past by saying something like "call contact voicemail" but today that didn't work. Other than changing the name of the contact, what can I do to get Siri to dial this contact?
I know your question states: Other than changing the name of the contact, what can I do to get Siri to dial this contact?, but you don't clarify why you don't want to do it this way?

I'm not aware of another way to do this, and in my case changing the contact name works flawlessly. I just created a contact called "Company Name Voicemail" and Siri has no problems whatsoever.

I just say, "Hey Siri, call..." and she just dials the number and I go from there.
