The following table describes all SIP parameters.

Parameter

 Description

SIP Max Forward value, which can range from 1 to 255. 

Defaults to 70.

Number of times an invite can be redirected to avoid an infinite loop. 

Defaults to 5.

Maximum number of times a request can be challenged. Ranges from 0-
255.

Defaults to 2.

Used in outbound REGISTER requests. If empty, the header is not included. 
Macro expansion of $A to $D corresponding to GPP_A to GPP_D allowed.

Defaults to $VERSION.

Server header used in responses to inbound responses. 

Defaults to $VERSION.

User-Agent name used in a REGISTER request. If not specified, the SIP User 
Agent Name is also used for the REGISTER request. 

Defaults to blank. 

Accept-Language header used. If empty, the header is not included.

Defaults to blank.

MIME Type used in a SIP INFO message to signal a DTMF event. This 
parameter must match that of the service provider.

Defaults to application/dtmf-relay. 

If set to yes, removes the last registration before re-registering (if the value 
is different). 

Defaults to no.

If set to yes, the SPA9x2 uses compact SIP headers in outbound SIP 
messages. If inbound SIP requests contain normal (non-compact) 
headers, the phone substitutes incoming headers with compact headers.

If set to no, the SPA9x2 uses normal SIP headers. If inbound SIP requests 
contain compact headers, the phone reuses the same compact headers 
when generating the response, regardless of this setting.

Defaults to no.

Setting this parameter to yes encloses the configured Display Name string 
(see 

) 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.

Defaults to yes.
