[cisco-voip] Cisco 7937G phone

[Collins, Matthew]

Hi All,



Had a few reports that some of our 7937 phones (about 15/50)  are not registering back after completing some SRST testing on a few sites. After doing some reading in the release notes it says



Support for Voice and Data VLANs

The Cisco Unified IP Conference Station 7937G uses a single 10/100BaseTx Ethernet LAN connection to communicate with the switch port. Because this connection carries only voice traffic, the switch port should belong to a single VLAN.



This means that you must configure a voice VLAN for the phone to function properly. You cannot configure voice and data VLANs on the same switch port.





Does anyone else remove the Data Vlan from the switch port for these phones, I have never done this in the past and would be a bit of a nightmare to implement as our local IT guys move these phones around all the time. Apart from this problem the phone perform as they should.



Phone firmware is apps37sccp.1-4-4-0

CUCM is 6.1.5 (upgrading soon)





All comments welcome
