line is bound to the POTS voice

entity.

15. Enable the VoIP gateway to register

numbers of the POTS voice entity

with the H.323 gatekeeper or SIP

server.

By default, after configured with

GK or SIP registration related

parameters, a POTS voice entity

initiates registration to the

H.323 gatekeeper or SIP server.

stream of the voice entity.

Configuring basic functions

After creating a POTS voice entity, you need to configure basic functions of the POTS voice entity.

Configuration guidelines

When you configure basic functions, follow these guidelines:

• Two communication parties can communicate correctly only if they share some identical codec

algorithms. Therefore, when you configure the compression command, make sure that the devices

on both sides share identical codec algorithms. Otherwise, the call will fail.

• Support for the codec algorithms varies with cards and the part related to the upper layer (voice

entity) is independent of hardware. Therefore, the upper layer only verifies the maximum range for

each codec. It is up to the DSP to determine whether the value within this range is valid according

to the hardware type. If yes, the upper layer sends the value. If not, the default value for the codec

is adopted. If you find that a configured packetization period does not take effect, first check

whether the value configured for the card and codec is valid.
