Sip-Options
###########

These scenarios check DHCP server SIP (Session Initiation Protocol) options.
SIP is used for VoIP telephony and video conferencing systems.
These options help IP phones and VoIP clients automatically discover SIP servers.
This includes: sip-server-name and sip-server-address (both use option 120 with different encodings).

***************************
Test SIP-Server-Name Single
***************************

Description
===========

This scenario checks the ``sip-server-name`` option with a single SIP server hostname.
The DHCP server configures a SIP server by domain name, and the client receives it.
SIP server names are encoded in a special hex format (Option 120, encoding type 0).
This is used by VoIP phones to locate SIP/PBX servers by hostname.

Test SIP-Server-Name Multiple
*****************************

Description
===========

This scenario checks the ``sip-server-name`` option with multiple SIP server hostnames.
The DHCP server configures three SIP servers by domain name for redundancy.
Multiple SIP servers provide failover for VoIP telephony systems.
