Für Openstage SIP Telefon kann man anstatt LLDP-MED auch über die DHCP Option 43 der DHCP Server konfigurieren konfigurieren.

DHCP Option 43 tags

When IP phone is booting, it first obtains an IP address from Native VLAN via DHCP! Data VLAN is often used as Data VLAN that is also used by customer’s computing device. Afterwards, IP phone reboots again with values given by vendor specific DHCP option (Otion 43). Option 43 gives you the ability to transmit configuration data to phine during phone’s boot sequence. Often customer’s phones are using a separate Voice VLAN for signaling and voice stream.

DHCP vendor specific option 43 specifies Voice VLAN ID and URL of DLS server. Siemens IP phones will recognize vendor specific options only, if vendor string (here: „Siemens“) matches correctly. All values are given in hexadecimal numbering format. Here is a detailed description of all DHCP option 43 bytes:

Tag Len Content (Example)
01  07  5369656d656e73
02  04  00000065
03  1a  73646c703a2f2f39332E3132322E3131342E39363a3138343433
ff


There are three Tags, each with an explicit length value. List if tags is delimited by a ending ff

  • Tag 01 specifies the vendor (here: Siemens)
    • Tag: 01; Length: 07; Value: Siemens
  • Tag 02 specifies VLAN ID of Voice VLAN (here: 101)
    • Tag: 02; Length: 04; Value: 65 (Hex)
  • Tag 03 specifies IP address of DLS-Server (here: 93.122.114.96:18443)
    • Tag: 03; Length: 1a; Value: sdlp://93.122.114.96:18443 (Hex)
  • End of record
    • End: ff (Hex)

Use Tag 04 instead of Tag 03 if URL of DLS is given by name (DNS).
