IPv6 Requires additional configuration when Auto is Configured

When Auto is set as the Signaling/Media Source IP field (in the SIP Signaling Group facing the Front End Server/Skype Mediation Server), call scenarios using IPv6 are not being transferred correctly. Most cases include a Skype Mediation Server or Front End Server which invokes call transfer (REFER SIP msg) incoming to the SBC Edge.

As a result, the following additional configuration is required for the calls to transfer correctly.

Step 1: Add Number/Name Transformation Entry

Add a Transformation Table (if the FQDN of the Skype Mediation Server/Front End Server is set as a pool), that includes a wildcard regex expression for the FQDN configured on the Transformation table (to match all Skype Mediation Server/Front End Servers within the pool).

For example:

If the Skype Mediation Server/Front End Server FQDN is "lync-rdc2.njsbclab.dev",  then ".*lync-rdc2.njsbclab.dev.*" regex expression must be configured as the Transformation entry.

If multiple Skype Mediation Server/Front End Server FQDNs, (i.e, sfbfe1.sfb.tst, sfbfe2.sfb.tst, ….) are configured within a pool, then “.*sfbfe..sfb.tst.*” regex expression must be configured as the Transformation Entry.

Step 2: Add Call Routing Table

Add a Call Routing Table which includes the following:

Lync E911 ELIN Support

Security desk conferencing with the emergency call in Unidirectional and Bidirectional mode is not supported.
