My company is about to upgrade to an SPA9000/SPA400 system using SPA942 phones all around the manufacturing shop offices. However, I need to have the ability to make announcements throughout the shop. How would I go about doing this?
I am not sure how many phones you have on your SPA9000 system, but think about the following.
The SPA9000 can register up to 16 IP hosts or in other wods 16 individual IP phones. As you must be aware, as you have the SPA9000 system, each of those phones can have multiple extensions. But the limitation as stated again is 16 IP hosts registered on the SPA9000.
Each of the Valcom VIP-130L that you add will take up one of those SIP registrants positions. Also the specs on that POE powered device indicate that it may not be very loud -10dBm, but double check if -10dBm is sufficient for your needs.
Maybe consider another valcom device that I have worked with before the Valcom 9970. This device plugs into FXS ports.
Dead easy to set up, but needs to run into amplified speakers.
The advantage of running into amplified speakers is that you can crank up or down the volume level of amplified speakers to suit the location. Also if you look at the valcom 9970 installation manual, multiple amplified speakers can be connected toa single Valcom 9970.
Why not take advantage of the two FXS ports built into the back of the SPA9000. Two Valcom 9970 could plug into the back of the SPA9000.
To activate the Overhead pager all you have to do is ring the extension of the FXS port, dead easy.
Or you may if you wish add a Cisco SPA8000 to the PBX, the spa8000 has eight FXS ports ,but appears to the SPA9000 as a single IP host with eight extensions. :-)
The advantage of using the SPA8000 in conjunction with the Valcom 9970 is that you now have the option if you want to of connecting ten Valcom 9970's to the SPA9000 phone system.
