1. Overview

This module collects extensions from Kamailio core.

Kamailio Core CookBook is available at: http://kamailio.org/dokuwiki/

2. Dependencies

2.1. Kamailio Modules

The following modules must be loaded before this module:

  • No dependencies on other Kamailio modules.

2.2. External Libraries or Applications

The following libraries or applications must be installed before running Kamailio with this module loaded:

  • None.

3. Functions

3.1. setsflag(flag)

Set the script flag.

Meaning of the parameters is as follows:

  • flag - the index of the script flag to be set. Can be integer or pseudo-variable with integer value.

This function can be used from ANY_ROUTE.

...
setsflag("1");
...
$var(flag) = 11;
setsflag("$var(flag)");
...

3.2. issflagset(flag)

Return true of the script flag is set.

Meaning of the parameters is as follows:

  • flag - the index of the script flag to be tested. Can be integer or pseudo-variable with integer value.

This function can be used from ANY_ROUTE.

Example 1.2. setsflag usage 

...
if(issflagset("1"))
{
    ...
}
...

3.3. resetsflag(flag)

Reset the script flag.

Meaning of the parameters is as follows:

  • flag - the index of the script flag to be reset. Can be integer or pseudo-variable with integer value.

This function can be used from ANY_ROUTE.

Example 1.3. resetsflag usage 

...
resetsflag("1");
...

3.4. setbflag(flag [, branch])

Set the branch flag.

Meaning of the parameters is as follows:

  • flag - the index of the branch flag to be set. Can be integer or pseudo-variable with integer value.

  • branch - the index of the branch whose flag to be set. Can be integer or pseudo-variable with integer value. If omitted, then branch 0 is used (R-URI).

This function can be used from ANY_ROUTE.

Example 1.4. setbflag usage 

...
setbflag("1");
...
$var(flag) = 11;
setbflag("$var(flag)", "1");
...

3.5. isbflagset(flag [, branch])

Return true of the branch flag is set.

Meaning of the parameters is as follows:

  • flag - the index of the branch flag to be tested. Can be integer or pseudo-variable with integer value.

  • branch - the index of the branch whose flag to be set. Can be integer or pseudo-variable with integer value. If omitted, then branch 0 is used (R-URI).

This function can be used from ANY_ROUTE.

Example 1.5. setbflag usage 

...
if(isbflagset("1"))
{
    ...
}
...

3.6. resetsflag(flag [, branch])

Reset the script flag.

Meaning of the parameters is as follows:

  • flag - the index of the script flag to be reset. Can be integer or pseudo-variable with integer value.

  • branch - the index of the branch whose flag to be set. Can be integer or pseudo-variable with integer value. If omitted, then branch 0 is used (R-URI).

This function can be used from ANY_ROUTE.

Example 1.6. resetsflag usage 

...
resetbflag("1");
...

3.7. km_append_branch([uri])

Append a new branch to SIP request.

Meaning of the parameters is as follows:

  • uri - SIP URI of the new destination. If omitted then the R-URI is used. It can be static string or a string with pseudo-variables that will be evaluated at runtime.

This function can be used from REQUEST_ROUTE and FAILURE_ROUTE.

Example 1.7. km_append_branch usage 

...
km_append_branch();
...
km_append_branch("sip:alice@sip-router.org");
...

3.8. setdsturi(uri)

Set the destination address URI (outbound proxy address).

Meaning of the parameters is as follows:

  • uri - Valid SIP URI representing the address where to send the request. It must be a static string, no variables are evaluated at runtime. If you need to set outbound proxy address via a variable, use assginment to $du.

This function can be used from ANY_ROUTE.

Example 1.8. >setdsturi usage 

...
setdsturi("sip:10.0.0.10");
...

3.9. resetdsturi()

Reset the destination address URI (outbound proxy address).

This function can be used from ANY_ROUTE.

Example 1.9. >resetdsturi usage 

...
resetdsturi();
...

3.10. isdsturiset()

Check if the destination address URI (outbound proxy address) is set.

This function can be used from ANY_ROUTE.

Example 1.10. >isdsturiset usage 

...
if(isdsturiset())
{
   ...
}
...

3.11. pv_printf(var, str)

Evalues the str and sets the resulted value to variable var. For backward compatibility reasons, same function can be executed via 'avp_printf(var, str)'.

Meaning of the parameters is as follows:

  • var - name of a writable variable

  • str - string that may contain variables which will be evaluated at runtime.

This function can be used from ANY_ROUTE.

Example 1.11. >pv_printf usage 

...
pv_printf("$ru", "sip:$rU@$fd");
pv_printf("$avp(x)", "From: $fU - To: $tU");
...

3.12. is_myself(uri)

Check if the parameter matches the 'myself' condition (i.e., is a local IP or domain).

Meaning of the parameters is as follows:

  • uri - Valid SIP URI or IP address to check against the list of local IP addresses or domains. The parameter value can contain pseudo-variables.

This function can be used from ANY_ROUTE.

Example 1.12. >is_myself usage 

...
if(is_myself("$fu")) {
    ...
