Description

Workaround

BTS10200:For G.729 Codec SS7 to SIP

Symptom: Scenario 1: SS7 to SIP Call

Interworking fails

IN CRCX BTS sends in Local Connection Options

 

 

a:G.729, and not "G729", so we changed the codec string

 

in VISM to match that and make it choose G.729a (Payload

 

type 18) codec.

 

Scenario 2: SIP to SS7 Call

 

With the above config in CRCX BTS does not send

 

anything in a: of Local Connection parameters and instead

 

sends SDP with m=18 0 8 102, here 18 is defined as "G729"

 

not "G.729" in an RTPmap attribute(a=rtpmap:18

 

G729/8000). Now with this CRCX VISM fails to

 

understand "G729" as the codec string in VISM is "G.729".

 

Workaround: The workaround is to use PCMA or PCMA

 

as the codec used in the call.

 

 

IPCMessage pool fills up at 40cps with

Symptom: IPC message queue is filling up causing a

ss7->ss7 traffic.

switchover while running ss7->ss7 traffic at 40cps with a

 

180 second hold time.

 

Workaround: Run the call agent at lower level of traffic.

 

 

TWC with CA switchover receive busy.

Symptom: After CA switchover twice, one party of a TWC

 

goes on-hook. Then the party that originate the TWC gets

 

busy.

 

Workaround: There is no workaround at this time.

 

 

Signal stop time is not generated for

Symptom: Continuation billing records are generated for a

call-type 24 in raw cdr file.

call that is no longer active. (Continuation billing records

 

are distinguished by the value of 1, 2, or 3 in the "Record

 

Type" field of the billing record.)

 

Workaround: Contact Cisco support to stop the

 

continuation billing records from being generated for the

 

non-active call.

 

 

If RKS server becomes unreachable EMA

Symptom: Event Message (EM) billing is enabled, a single

doesn’t try to re-establish a connection.

Record Keeping Server (RKS) is equipped and in service,

 

but EMs do not get sent to the RKS.

 

Instead, they are always written to disk.

 

Workaround: Unequip the RKS by removing the

 

radius-profile info via "change call-agent-profile".

 

Re-equip the RKS by restoring the radius-profile info via

 

“change call-agent-profile.” Within a few minutes, normal

 

communication should resume. ("A few minutes" equals

 

the value of RETRY-PRI-RKS-TIMER (in ca-config table),

 

if defined. If not defined, it equals three minutes.)

BTS 10200 specifications

Cisco Systems BTS 10200 is a robust platform designed to meet the demands of modern telecommunications. This session border controller (SBC) facilitates the management of voice over IP (VoIP) traffic, enabling secure and efficient communication across diverse networks. The BTS 10200 plays a critical role in integrating voice and data services while ensuring high-quality user experiences and regulatory compliance.

One of the standout features of the BTS 10200 is its ability to support a wide range of protocols, making it highly versatile. It is compatible with both legacy systems and modern IP-based solutions, ensuring seamless interoperability. This adaptability allows service providers to migrate to next-generation networks without disrupting existing services.

The BTS 10200 is built upon a highly scalable architecture, allowing it to handle large volumes of traffic. This scalability is crucial for service providers as they expand their networks to accommodate more users and services. The platform supports hundreds of thousands of simultaneous sessions, which is essential for large-scale deployments such as in mobile and fixed-line networks.

Security is a paramount feature of the BTS 10200. It incorporates multiple layers of security protocols, including encryption and authentication mechanisms, to protect against unauthorized access and potential cyber threats. The platform also features robust filtering and Denial of Service (DoS) protection, ensuring that VoIP services remain stable and reliable even under adverse conditions.

Quality of Service (QoS) management is another critical characteristic of the BTS 10200. It allows for traffic prioritization to ensure that voice signals maintain clarity and reduce latency. Through advanced traffic shaping and management techniques, service providers can enhance the overall user experience even during peak usage periods.

Furthermore, the BTS 10200 supports a wide array of management and monitoring tools, enabling network administrators to gain insights into performance metrics, traffic trends, and system health. This data-driven approach allows for intelligent decision-making and proactive maintenance.

In summary, the Cisco Systems BTS 10200 is a powerful, secure, and scalable solution for managing voice and data services in today's complex telecommunications environment. Its combination of protocol support, robust security measures, QoS capabilities, and management tools positions it as a key asset for service providers looking to enhance their offerings and ensure reliable communications for their users.
