Hi I’m working at a small shop and they are trying to get away from a local company and switch to spectrum enterprise. Enterprise has a min of 8 SIP trunk lines, but we currently only have adi licensing for 6. After hearing they don’t make adi licenses anymore I was told I should upgrade to R11 from R9.1 and migrate the adi licenses. I was quoted about $700 and I was wondering what my best course of action should be. Is it worth it to pay $700 for the newest release and 2 trunks or should I just pay for 8 trunks and only use 6. Thanks for your input!
