This is the most likely candidate for installation in a majority of cases. 1 analog output, 1 analog input, multicast output, 2 relay switches.
- Default password is moonbase
- Multicast must not be blocked on the network for configuration tool to operate normally.(some switches\routers will block multicast)
- There is no "factory reset", but you can backup an initial config to restore later. Recommend this as first configuration step.
- Yealink phones can be configured to receive multicast audio from the Valcom(220.127.116.11:4098). Useful for testing media server --> Valcom connection is working, before wiring in analog speakers.
- The Valcom will make a distinct "click" sound when it answers a page, whether or not you successfully get audio from speakers\phones. This is the relay switch toggling.
- Firmware hosted on website is outdated. Newer version from Valcom support is attached to this article -- vip201-r223-17-Sep-2012-firmware.tar
- DNS lookups for SRV and A-records is spotty, recommend using server ip addresses for registration.
- NAT traversal for audio will fail despite valid STUN settings
- Workaround #1: Enable the Pre-announce tone. This allows asterisk comedia to detect the correct port to send the page audio to. (Most closely emulates a standard SIP phone)
- If you need the announce tone removed, but use this workaround to correct NAT, load our *unofficial* custom firmware attached to this article - vip201-r223-FS-silence-firmware.tar.(replaces tone with silence)
- Workaround #2: Setup the Valcom with it's own dedicated static ip address.
- Workaround #3: Utilize a router with a good SIP-ALG that will re-write the SIP packets with the correct NAT info. (Actiontec C1000a from CenturyLink is an example of a working router\modem)
- Polycom phones do not properly receive multicast audio.(Polycom has it's own multicast standard)
- POE power is the only reliable power source(that we have found), unless you have the official power supply from Valcom.
