For a medium to small size company (8 channels of Business SIP) that have offices in 5 countries (Dubai, UK, Malaysia, USA, Brazil to name a few) they will need to call these locations fairly often. The issue is that there doesn't seem to be any calling plans that cover this type of call on SIP. What options do we have? I don't want them to end up with massive call costs per month. What options are there for them?
Thanks in advance.
