The outbound proxy is an intermediate server that processes all VoIP
requests and connections going to the provider (except for registration).
automatique
The PBX automatically determines an outbound proxy.
Manuel Port
The outbound proxy is a fixed default setting. Enter this data as an IP
address or a URL.
Note: The Synthèses > Ports page shows an overview of the PBX
ports (incoming and outgoing).
SIP port (1 to 65535)
The SIP port on the PBX is used both as an incoming port and an
outgoing port (i.e. for communications with the VoIP provider).
Note: A different SIP port must be used for each VoIP provider.
Note: The SIP port for a VoIP provider cannot be the same as the Port
SIP du registre VoIP interne or the Port SIPS du registre VoIP interne.
Note: The Synthèses > Ports page shows an overview of the PBX
ports (incoming and outgoing).
SIP session timer (5 to 60 min.)
At the specified intervals, the SIP session timer checks whether the
connection is still present. (The PBX cannot detect whether a call
connection is disrupted due to problems on the provider side.)
