Frequently Asked Questions


Can Talking SIP be deployed in either a centralized or decentralized configuration?

Yes, Talking SIP's architecture is designed specifically to give the service provider the flexibility to service any point of presence either at a local node level or from a central location without any additional licensing cost.

How scalable is Talking SIP?

Talking SIP scales from a starting density of 30 sessions/concurrent callers to thousands of concurrent callers.  As many as 2,000 sessions/concurrent callers are supported in a single node/blade. Additional nodes can be easily added to a network, while utilizing a centralized database, in order to scale out the network.  Network size and scale is a function of the server hardware in which it is running on.  Example Talking SIP call processing and database hardware configurations can be found on our website by clicking here: http://www.ivr.com/talking-sip-server

How redundant is Talking SIP?

Each component in the Talking SIP architecture can be easily made redundant. There are many available options ranging from the License Manager level, communications node, to the database level for replication/failover, all the way to clustering for mission critical implementations -- all options are cost effective and readily available.

Does Talking SIP support RADIUS?

Talking SIP is an advanced SIP based solution utilizing advanced VoIP signaling in order to provide real-time media, application and billing services to a wide assortment of SIP based devices. By being a pure SIP solution Talking SIP is an intelligent solution that offers real-time call state management, media streaming (in all of the popular codecs) along with broad industry interoperability. RADIUS is a legacy technology that was initially used for dial up modem authentication and is a limiting method of providing AAA services in a VoIP deployment. Some of these limitations include lack of industry support across varying devices, inefficient use of network resources in order to service a call, complicated and limited TCL call scripting and limited and hard to manage TFTP voice prompting.

Does Talking SIP support postpaid/wholesale billing models?

Yes, Talking SIP comes standard with support for postpaid/wholesale billing including support for real-time credit limit enforcement and account invoicing. Callers can be authenticated by the SIP URI From/To information, an IP address from a peering partner's gateway, carrier code, SIP registration credentials, Remote-Party-ID, DNIS or  ANI.

My Company is interested in deploying Vonage type services, is Talking SIP suitable for this application?

Yes, Talking SIP is commercially deployed in various countries providing primary and secondary line services for residential and business users accessing the network via softphones, IADs and IP phones. This is a popular application for the use of our product in order to provide tandem switching, media streaming of voice prompts and real-time billing for both flat-rate/packaged and per minute subscriber offerings.

Can I administer Talking SIP remotely and monitor system activity?

Talking SIP comes complete with our Telephony Management Console that allows varying levels of access in order to perform system administration across a global network from a single login session.

How do I integrate other Class 5 services such as voicemail and conferencing?

Talking SIP provides Class 5 services and optional voice mail and optional three-way conferencing capabilties, and it also interoperable with varying SIP based solutions (premise-based and hosted) allowing the service provider to select best of breed solutions for integration into the overall network, helping to build margins and drive revenue.

Can Talking SIP be securely provisioned in order to provide specific levels of access based on job category or the commercial role in the network?

Yes, Talking SIP's Telephony Management Console can be provisioned in order to provide very granular level access to users that are enrolled in varied user groups. These user groups contain the selected access rights made available from the Telephony Management Console menu. Those areas of the system where access is not being provided are entirely removed from the menu thus eliminating potential questions from users. Talking SIP has been designed from the ground up to be successfully deployed in hosted and/or self managed models.

What types of devices does Talking SIP interoperate with?

Talking SIP interoperates with any RFC 3261 compliant softphone, IAD, gateway, softswitch, IP phone, session border controller (SBC) and/or proxy server. While we continually test with best of breed industry partners and welcome the opportunity to engage with other market leaders as our customers' needs require.

What does Talking SIP require for successful interoperability?

Talking SIP is compliant with SIP RFC 3261 and relies on support for the RFC 2833 and/or SIP INFO methods for DTMF recognition, which is used when the caller will be prompted for DTMF digits for an account number and/or a destination number. Please note that with RFC2833 Talking SIP uses Named Telephone Events with a Payload type of 127, and with SIP INFO uses the Cisco implementation. The other requirement is for support for the SIP REINVITE for two stage dialing applications, to allow the redirection of the media streams directly between the endpoints while Talking SIP continues to maintain full control of the signaling to enable real-time call cut off.

What type of documentation and other installation tools are shipped along with the Talking SIP software?

Talking SIP ships standard with over 900 pages of professionally written documentation along with a context sensitive on-line help system that is always available through the management interface by simply hitting the F1 key.

Other fraud prevention features include; up to 40 digit randomized account number generation, second level PIN prompting, single simultaneous use account enforcement (can be toggled on/off at system administrator discretion) as well as informative risk management reports to help run a secure network.

How is Talking SIP licensed?

Talking SIP employs a centralized license manager that promotes efficient use of resources across a globally deployed network. High availability and efficient resource utilization are key considerations to the success of any mission critical and distributed network. By centralizing the licensing of Talking SIP, network operators avoid situations where there is blocking occurring at one network point while idle capacity sits at another. Session licenses can be allocated on a first come first serve basis or pre-allocated on a SIP endpoint-by-endpoint basis. As opposed to enforcing licensing within Talking SIP at the network's edge -- this licensing architecture encourages service providers to distribute the processing load across multiple servers for redundancy and performance considerations since there are no financial licensing disincentives to scaling out one's network.
