Description

Telesis systems support for SIP and H.323 protocols. Both protocols coexist on the same Telesis system. SIP and H.323 calls may originate and terminate in the same system. Furthermore, Telesis systems allow calls from SIP based devices to be routed to H.323 based devices and vice versa. With this interoperability, enterprises may have the ability to use both protocols in the same network. 

General Capabilities

Telesis systems can register to both SIP registrar/proxy/servers and H.323 gatekeepers at the same time. This allows address resolution of a Telesis system from either side and results in flexibility for multipath VoIP access applications. Furthermore, Telesis systems have both integrated H.323 gatekeeper and external gatekeeper registration capability at the same time. Similarly, Telesis systems have both integrated SIP registrar and external registrar registration capability at the same time. Coexistence of all these capabilities allows:

  • SIP users to call SIP users in private address space
  • SIP users to call H.323 users in private address space
  • SIP users to call SIP entities in public network
  • SIP users to call H.323 entities in public network
  • SIP users to call legacy PSTN via TDM interfaces 
  • H.323 users to call H.323 users in private address space
  • H.323 users to call SIP users in private address space
  • H.323 users to call H.323 entities in public network
  • H.323 users to call H.323 entities in public network
  • H.323 users to call legacy PSTN via TDM interfaces
  • Legacy PSTN users to call any H.323 and SIP entities

Telesis systems can register to both SIP registrar/proxy/servers and H.323 gatekeepers at the same time. SIP user agents and H.323 user may also register to the Telesis systems.

A Telesis system has both integrated SIP registrar and H.323 gatekeeper for users. Furthermore, it is possible to register to multiple SIP registrars and H.323 gatekeepers at the same time.

Telesis systems try to have the media transport directly between the connecting IP entities. However, in some cases like IP-TDM, TDM-IP, SIP-H.323, H.323-SIP calls, this is not possible or efficient. In such cases, switching and media proxying capabilities in Telesis systems route calls from one side to the other.
