Unity License for SIP Sessions

[ShankarP]

Hi everyone, would like to check if there is any license requirement for the number of ports (channels) that we can configure between CUCM and Unity. (for both SCCP & SIP Integration). Thanks

Hi, there are no license for the SIP sessions. It's all depending on the hardware of your Cisco Unity machine. You can take a look on this document which describes the capacity for each deployment:

Basically the ova you select during install determines your port capacity.

Just to tag on here, Unity Connection used to be licensed per voicemail ports few versions ago, but now you get as many ports as available per the size of the VM plus the type of codec you use, i.e. if you iLBC or G722 your capacity goes down by factor of 4:
