## SIP_CONTROLLER_LIST specifies a list of IPv4 SIP controller designators,
## separated by commas without any intervening spaces.
## The list is used on IPv4-only and dual mode phones (if�SIP_CONTROLLER_LIST_2 is not provided).
## Each controller designator has the following format:
## host[:port][;transport=xxx]
## host is an IP address in dotted-decimal (DNS name format is not supported unless stated otherwise below).
## [:port] is an optional port number.
## [;transport=xxx] is an optional transport type where xxx can be tls, tcp, udp or auto.
## "auto" means that the preferred transport is determined based on Name Authority Pointer (NAPTR) record retrieved for the SIP Controller FQDN configured. SRV records can be then used to retrieve port and the final FQDN for use.
## If a port number is not specified a default value of 5060 for TCP and UDP or 5061 for TLS is used.
## If a transport type is not specified, a default value of tls is used.
## The value can contain 0 to 255 characters; the default value is null ("").
## This parameter is supported by:
## J129 SIP R1.0.0.0 (or R1.1.0.0); J100 SIP R2.0.0.0 and later; J139 SIP R3.0.0.0 and later, J159 SIP R4.0.3.0 and later, J189 SIP R4.0.6.1 and later
## For Aura environment, FQDN format is supported for J100 phones starting R4.0.11.0
## For the FQDN, DNR SRV records are not used, only DNS A and AAAA records are used.
## If the list contains a mix of FQDNs and IP addresses, only FQDNs will be used, IP addresses will be ignored.
## For OpenSIP environment, only one SIP controller is supported.
## "auto" is supported in OpenSIP environment only. "auto" is supported by J100 SIP R4.0.0.0 and later.
## J100 SIP R4.0.0.0 and later; used on dual mode phones if�SIP_CONTROLLER_LIST_2 is not provided.
## When 3PCC_SERVER_MODE = 1 (a BroadSoft server), SIP_CONTROLLER_LIST should contain one sip controller entry and host should be an FQDN (DNS name format).
## The FQDN would resolve to primary and alternate servers to support redundant configuration.
## When 3PCC_SERVER_MODE = 0 (a generic SIP server), SIP_CONTROLLER_LIST may contain one or two sip controller entries (to support redundant configuration).
## �host� of sip controller entry could be an FQDN(DNS name format) or an IP address. If FQDN is provided, it will resolve to one primary server.
## IPv6 is not supported for OpenSIP environment. In OpenSIP environment, there is no support for resolving an FQDN to an IPv6 address in the SIP_CONTROLLER_LIST or SIP_CONTROLLER_LIST_2.
## IPv6 is supported for Aura environment and in Aura there is no support for FQDN yet (only IP addresses can be configured).
## J169/J179 SIP R1.5.0
## Avaya IX Workplace 3.1.2 and later; DNS name format is supported.
## Avaya Vantage Devices SIP R1.0.0.0 and later; DNS name format is supported; UDP is not supported; not applicable when Avaya Vantage Open application is used.
## IPv6 address is supported as well for Aura environment only. SIP_CONTROLLER_LIST_2 is not supported.
## Avaya Vantage Connect Application SIP R1.0.0.0 and later; DNS name format is supported; TCP/TLS are supported in Avaya Aura, Avaya IP Office and OpenSIP environments. UDP is supported in OpenSIP environment only.
## OpenSIP environment is supported from R2.0.1.0 and later. The configuration file from the Avaya Vantage Device combines the configuration of this parameter from all sources (in the following order):
## UI, LLDP, DHCP, this file, PPM and AADS. R2.2.0.0 and later - IPv6 address is supported as well for Aura environment only. Please note that for dual stack controllers (IPv4/IPv6),
## then FQDN shall be used to avoid multiple registration to the SAME controller over both IPv4 and IPv6 addresses. SIP_CONTROLLER_LIST_2 is not supported.
## 96x1 SIP R6.0 and later
## 96x0 SIP R2.4.1 and later
## H1xx SIP R1.0 and later; udp is not supported.
