P2P-SIP mode

1. Set the IP telephone, not requiring registering with a PBX, assigning it an extension and the

required data to make a call

(11)

. It is important the telephone to have the capacity of

understanding the audio codec G711-A, which is the one used by E451.

2. Set the E451, assigning an extension to each one of them.

3. In each one of the E451 units, configure the callee device extension and IP address in a “push-to-

call” application. In this mode it is not possible to transfer calls.

4. If all the units are correctly configured, they are capable of communicating.

Communication process

When activating one of the E451 intercoms push button, the communication establishment request

begins. The vocal communication between the telephone and the intercom may begin when picking up

the phone.

Likewise, the telephone can communicate with any of the E451 just by calling the corresponding

extension. E451 is ready to emit an incoming call warning tone. The call is answered by pressing the

button and thus begins the vocal communication with the telephone.

Any of both links can close he communication: from the telephone or from E451 by pressing the button.

As we have seen, the E451 button or the corresponding input in E401 have a triple functionality: call,

answer a call and hang up.

(11) The aim of this document is not to explain the settings of all the IP telephones available in the market. Please consult the each manufacturer for that.
