Using rtpcatch to Analyze Common Causes of Failure

The following examples show the rtpcatch output of failed fax sessions. <3.200> is ATA; <2.53> is a Cisco gateway.

Example 7-6 Cisco ATA Configuration Failure

Codec G723

Analysis

<2.53> is the originating gateway and <3.200> is the terminating Cisco ATA.

The Cisco ATA and the <2.53> gateway use G.723 codec.

Possible Causes for Failure

The Cisco ATA is not configured with fax mode or fax pass-through mode.

If the Cisco ATA is the gateway for a fax sender, the remote gateway is not configured with fax pass-through mode.

Analysis

<2.53> is the originating gateway and <3.200> is the terminating Cisco ATA.

The Cisco ATA and the <2.53> gateway begin with G.711 codec.

The <2.53> gateway sends Cisco fax relay event packets.

Possible Cause for Failure

Cisco fax relay option is not disabled on the gateway.

Analysis

<2.53> is the originating gateway, and <3.200> is the terminating Cisco ATA.

The Cisco ATA upspeeds to G.711µ-law and sends G.711 upspeed NSE signaling packets.

The <2.53> gateway does not respond to the NSE signaling packets.

ATA 188 specifications

The Cisco Systems ATA 188 is a versatile Analog Telephone Adapter designed to facilitate the integration of traditional telephone systems with Voice over Internet Protocol (VoIP) networks. This device has been key in bridging the gap between legacy telephony and modern IP-based communication, allowing users to leverage their existing analog phones while enjoying the benefits of digital connectivity.

One of the main features of the ATA 188 is its ability to connect regular analog phones to a VoIP network, enabling users to make and receive calls over the internet. This significantly reduces calling costs, especially for long-distance and international calls. The ATA 188 supports two phone lines, allowing simultaneous voice calls. This dual-line capability makes it a suitable choice for small businesses or home offices that require multiple lines without the need for extensive infrastructure.

The device is equipped with various technologies that enhance its functionality. It supports the Session Initiation Protocol (SIP) and H.323, making it compatible with a wide range of VoIP service providers. Additionally, the ATA 188 features Quality of Service (QoS) settings, which prioritize voice traffic over the internet, ensuring clear voice quality without interruptions or delays. This is essential for maintaining a professional communication experience, especially in business environments.

Another characteristic of the ATA 188 is its user-friendly configuration interface. It allows users to easily set up and manage their devices through a web-based portal. The configuration process is straightforward, with options to adjust settings such as codec selection, call features including call waiting, and call forwarding functionalities.

Security is also a priority for the ATA 188, as it provides robust protocols to protect call data. The device supports Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS) to encrypt voice traffic and manage signaling securely. This ensures that sensitive conversations remain confidential.

Overall, the Cisco Systems ATA 188 is a reliable and efficient solution for users looking to transition from traditional telephony to VoIP. Its dual-line capacity, compatibility with multiple VoIP standards, user-friendly configuration, and built-in security features make it a valuable asset for both personal and professional communication solutions. In an ever-evolving telecommunications landscape, the ATA 188 remains a relevant and practical choice for integrating legacy telephony with modern internet-based services.
