LST File Format

The LST file format is as follows: 

<localSubscriberTable>
<subscriber username="sip:alic!.*!@open-ims.lst" ifcid="1"/>
<subscriber username=”tel:4832376630!.*!”  “ifcid=2”/>
</localSubscriberTable>

The LST file’s elements includes the subscribers' elements. This element has the subscriber information. And has the following attributes:

  • username—Either Tel-URI or SIP-URI identifying the end station for which services are executed.
  • ifcid—Pointer to service execution ID (iFC).

Overlapping LST Entries Not Supported

The best-match function for LST table entries is not supported in this release. You can create distinct PSI and wildcard PSI entries in the LST table. But the pattern of these entries cannot overlap. Currently, the OCCSM does not support recursive searches on LST entries. Therefore, the OCCSM does not identify entry best match.

For example, the two LST entries shown below are overlapping patterns, and must not be in the same LST table:

  • sip:alic!.*!@open-ims.lst
  • sip:ali!.*!@open-ims.lst

Note that the AOR alice@open-ims matches both entries, with “sip:alic!.*!@open-ims.lst” being the best match. In this software version, the OCCSM uses the first entry it finds instead of the best match.
