I’d to move a number of hardware UCM’s to a hosted multi-tenant SoftwareUCM instance.
I’d like to have this instance behind NAT to avoid burning a preciously valuable public IP for each SoftwareUCM tenant. Doing this will require port forwarding all of the necessary ports to the correct SoftwareUCM tenant. SIP is no big deal, it’s just one port; however, RTP by default has a range of 10,000 ports. Is that number necessary? If that’s the case, then when port forwarded, I’ll only be able to get at the absolute most 6 tenants per public IP address.
Has anyone else come across this? What was your resolution?
As a side note, I’ve also been trying FusionPBX for a while and it has ran very well. Their multi-tenancy configuration works differently wherein it does not require unique ports for each tenant (works on more of what I’d call an interface layer).
