摘要：

DTMF信号作为拨号音信号不仅可以实现拨号业务,而且可以通过SIP扩展的方法实现更多的增值业务。文中主要对SIP扩展的INFO方法和事件通告机制进行了阐述,对两者传送DTMF信号的方法进行了分析和比较。实现了DTMF的带外传送。

关键词: DTMF, INFO, 事件通告机制

Abstract:

As a dial tone signal,DTMF signal can be achieved not only in dial-up business,but it can be achieved for more value-added services through the extensions of SIP.In this paper,the extensions of SIP INFO methods and event notification mechanisms are described,and the two methods for transmitting DTMF signal are analyzed and compared.The out-band transmission of DTMF is realized.

Key words: dual-tone multi-frequency;INFO;event notification mechanism
