Linksys SPA 900 Series Manual De Usuario

Remove Last Reg 

Lets you remove the last registration before registering a new one if the value is different. 
Select yes or no from the drop-down menu. 

Defaults to no.

Use Compact Header 

Lets you use compact SIP headers in outbound SIP messages. Select yes or no from the 
drop-down menu. If set to yes, the Linksys IP phone uses compact SIP headers in 
outbound SIP messages. If set to no, the Linksys IP phone uses normal SIP headers. If 
inbound SIP requests contain compact headers, Linksys IP phone reuses the same compact 
headers when generating the response regardless the settings of the <Use Compact 
Header> parameter. If inbound SIP requests contain normal headers, Linksys IP phone 
substitutes those headers with compact headers (if defined by RFC 261) if <Use Compact 
Header> parameter is set to yes.

Defaults to no.

Escape Display Name 

Lets you keep the Display Name private. Select yes if you want the Linksys IP phone to 
enclose the string (configured in the Display Name) in a pair of double quotes for 
outbound SIP messages. Any occurrences of or \ in the string is escaped with \ and \\ inside 
the pair of double quotes. Otherwise, select no. 

Defaults to yes.

If set to yes, unit will include c=0.0.0.0 syntax in SDP when sending a SIP re-INVITE to 
the peer to hold the call. If set to no, unit will not include the c=0.0.0.0 syntax in the SDP. 
The unit will always include a=sendonly syntax in the SDP in either case. 

Defaults to yes.

Random REG CID On Reboot

If set to yes, the Linksys IP phone uses a different random call-ID for registration after the 
next software reboot. If set to no, the Linksys IP phone tries to use the same call-ID for
