SL1000 License Structure Explained (VRS + Voicemail)

There are some confusion over the number of VRS and Voicemail port access, especially on the usage of default number of ports and license usage. 

I will do a detailed explanation over here. 

First Thing we need to understand the hardware requirement for both VRS & Voicemail. In the SL1000 hardware lineup, below shows you the hardware required;

• PZ-VM21 (serves as a holder to put in the Compact Flash CF card) - CF slot
• Type of CF available (either of the 3 cards);
• IP4WW-CFVRS-C1 (only have VRS functionality) = 512MB
• IP4WW-CFVMS-C1 (both VRS & Voicemail Functionality) =512MB
• IP4WW-CFVML-C1 (both VRS & Voicemail Functionality) =1GB

Just treat CFVMS as VM short (approx. 15 hours storage), CFVML as VM long (approx. 40 hours storage). 

Second Thing let's understand the default number of ports for both VRS/Voicemail. Please see below;

• IP4WW-CFVRS-C1, default 4 ports access (VRS)
• IP4WW-CFVMS-C1, default 4 ports access (VRS) + 2 ports access (VM)
• IP4WW-CFVML-C1, default 4 ports access (VRS) + 4 ports access (VM)

Now that you understand the default number of ports. Lets discuss further on expanding the ports access.

Third Thing let's look into the ports expansion for both VRS + VM. Please see below;

• IP4WW-CFVRS-C1, default 4 ports access (VRS)
• IP4WW-CFVMS-C1, default 4 ports access (VRS) + 2 ports access (VM)
• IP4WW-CFVML-C1, default 4 ports access (VRS) + 4 ports access (VM)

• FOR VRS PORTS: To expand up to 16 ports access, simply you just need to buy the memory card IP4WW-MEMDB C1 and insert it into the CPU card. By this action you will have automatically 16 ports for VRS access. This statement applies for all the 3 CF cards
• FOR VM PORTS: To expand both CFVMS & CFVML voicemail ports access from 2 and 4 ports respectively, you will need to purchase the following license SL-VM-CHANNEL-2 LIC. This license per quantity will give you 2 ports expansion. You can expand the voicemail port access up to a maximum of 16 ports access. IMPORTANT: YOU WILL NEED THE MEMORY CARD IP4WW-MEMDB C1 when you are expanding beyond 8 ports voicemail access
