I don't want to sound snarky by questioning what's probably an org mandated tool usage, but I can't quite believe companies where there's only one accepted way to get in contact. Ideal would be a live conference call (phone, Skype, Hangouts etc...), but you've got SMS, email, heck, I once solved a pressing issue with my team in a Sharepoint Word document where all our comments were just new paragraphs being edited live (which actually had the handy benefit of being savable without needing to pay extra for the privilege...).
