Whitelist dynamic IP

Client I’m working for is running a sophisticated VoIP system through a dedicated DSL circuit with a static IP.

I’ve setup a MT on new DSL service which is faster and cheaper, however it’s limited to a dynamic IP. Phone guy says he needs a static IP on the VoIP (for whitelisting into his servers) and he can’t work with my dyndns URL. Any clever ideas how this can be accomplished?

Thanks in advance,
Scott

By the way, what’s up with the ‘just joined’?

you need a fixed ip for this … or they must whitelist all the isp’s ranges…

Yeah, this is what I thought - thanks for the confirmation!
