Reg Retry Long

When registration fails with a SIP response code that does

Intvl

not match

 

Retry Reg RSC, the ATA device waits for the specified

 

length of time before retrying. If this interval is 0, the ATA

 

device stops trying. This value should be much larger than

 

the Reg Retry Intvl value, which should not be 0.

 

The default is 1200.

 

 

Reg Retry Random

Random delay range (in seconds) to add to Register Retry

Delay

Intvl when retrying REGISTER after a failure.

 

The default is 0, which disables this feature.

 

 

Reg Retry Long

Random delay range (in seconds) to add to Register Retry

Random Delay

Long Intvl when retrying REGISTER after a failure.

 

The default is 0, which disables this feature.

 

 

Reg Retry Intvl Cap

The maximum value to cap the exponential back-off retry

 

delay (which starts at Register Retry Intvl and doubles on

 

every REGISTER retry after a failure). In other words, the

 

retry interval is always at Register Retry Intvl seconds after

 

a failure. If this feature is enabled, Reg Retry Random Delay

 

is added on top of the exponential back-off adjusted delay

 

value.

 

The default value is 0, which disables the exponential back-

 

off feature.

Response Status Code Handling section

SIT1 RSC

SIP response status code for the appropriate Special

 

Information Tone (SIT). For example, if you set the SIT1 RSC

 

to 404, when the user makes a call and a failure code of

 

404 is returned, the SIT1 tone is played. Reorder or Busy

 

tone is played by default for all unsuccessful response

 

status code for SIT 1 RSC through SIT 4 RSC.

 

 

SIT2 RSC

SIP response status code to INVITE on which to play the

 

SIT2 Tone.

 

 

SIT3 RSC

SIP response status code to INVITE on which to play the

 

SIT3 Tone.

The Cisco Systems SPA2102 is a versatile Voice over Internet Protocol (VoIP) adapter that serves as a bridge between traditional telephony systems and modern IP networks. Designed primarily for small to medium businesses, the SPA2102 is highly regarded for its reliability, ease of use, and rich feature set. This device allows users to make and receive phone calls over the internet while maintaining the ability to connect traditional analog phones.

One of the standout features of the SPA2102 is its dual-port capability. The device includes two FXS ports, allowing users to connect two separate analog telephones. This makes it an ideal choice for businesses that want to retain their existing telephony infrastructure while transitioning to a VoIP system. The ability to utilize two telephone lines simultaneously provides flexibility and convenience, especially for users in a busy office environment.

The SPA2102 leverages Session Initiation Protocol (SIP) technology, which is widely recognized for its robustness and interoperability. The support for SIP ensures that the SPA2102 can work seamlessly with various VoIP service providers, offering users a broad range of options for their telecommunication needs. In addition to SIP, the device supports various codecs, including G.711, G.726, and G.729, allowing for flexible audio quality settings and bandwidth management.

Security is also a critical aspect of the SPA2102. It incorporates advanced encryption methods, such as Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS), to protect voice communications from potential eavesdropping. This focus on security makes the SPA2102 a reliable choice for businesses concerned about the confidentiality of their conversations.

The device is easy to configure and manage, thanks to its web-based interface. This allows administrators to quickly set up the adapter, manage network settings, and troubleshoot any issues that may arise. Furthermore, the SPA2102 supports Quality of Service (QoS) features, ensuring that voice traffic is prioritized over other types of network traffic, which enhances call quality and reliability.

Overall, the Cisco SPA2102 is a powerful, user-friendly VoIP adapter that combines traditional telephony with modern IP technology. Its dual-port capability, support for SIP, extensive security features, and ease of configuration make it a solid choice for businesses looking to innovate their communication systems while minimizing disruption. Whether used in a small office or a larger organizational setting, the SPA2102 continues to be a reliable component of VoIP solutions.
