DESCRIPTION
Select whether or not to include the SIP service domain name when the V500
sends the SIP number.
SIP - include the SIP service domain name
TEL - do not include the SIP service domain name
Enter the number of seconds your SIP account is registered with the SIP register
server before it is deleted. The V500 automatically tries to re-register your SIP
account when one-half of this time has passed. (The SIP register server might
have a different expiration.)
Enter the number of seconds the V500 waits before it tries again to register the
SIP account, if the first try failed or if there is no response.
Select this to have the V500 use the setting you configure in the Session Expire
field. If you do not select this, the V500 does not automatically disconnect calls.
Enter the number of seconds the conversation can last before the call is
automatically disconnected. Usually, when one-half of this time has passed, the
V500 or the other party updates this timer to prevent this from happening.
Enter the minimum number of seconds the V500 accepts for a session expiration
time when it receives a request to start a SIP session. If the request has a shorter
time, the V500 rejects it.
Enter the listening port number(s) for RTP traffic, if your VoIP service provider
gave you this information. Otherwise, keep the default values.
To enter one port number, enter the port number in the Start Port and End Port
fields.
To enter a range of ports,
• enter the port number at the beginning of the range in the Start Port field
• enter the port number at the end of the range in the End Port field.
Select the type of voice coder/decoder (codec) that you want the V500 to use.
G.711 provides high voice quality but requires more bandwidth (64 kbps).
• G.711A is typically used in Europe.
• G.711u is typically used in North America and Japan.
• G.722 provides excellent sound quality and operates at 48 ~ 64 kbps.
• G.722.2 is similar to G.722 but allows for greater voiceband compression
when the network is congested.
• G.726 operates at 16, 24, 32 or 40 kbps.
• By contrast, G.729 requires only 8 kbps.
• G.723 refers to G.723.1, which uses 5.3 or 6.4 kbps.
The V500 must use the same codec as the peer. When two SIP devices start a
SIP session, they must agree on a codec.
Select the V500's first choice for voice coder/decoder.
Select the V500's second choice for voice coder/decoder.
Select the V500's third choice for voice coder/decoder.
