Abstract
Aspects of the subject disclosure may include, for example, a method for receiving, by a system comprising a processor, a first request to transition a communication device between a hearing mode and a teletype mode, and transmitting, by the system, a SIP command to a telecommunication network to switch between registration and deregistration of the communication, where the SIP command is transmitted responsive to expiration of a period for disabling switching between the registration and the deregistration. Other embodiments are disclosed.
Claims20
A communication device comprising:
- a memory to store executable instructions;
- and
- a processor communicatively coupled to the memory, wherein the processor, responsive to executing the executable instructions, performs operations comprising:
- receiving an input from a user interface requesting a transition from a hearing mode to a teletype mode;
- generating a first session initiation protocol (SIP) command for switching from registration to deregistration of the communication device at a telecommunication network responsive to the input, wherein the first SIP command initiates deregistration of the communication device when transitioning from the hearing mode to the teletype mode;
- determining whether a disable registration period has been started;
- initiating the disable registration period responsive to the disable registration period not having been started;
- determining whether the disable registration period has expired responsive to the disable registration period having been started;
- transmitting the first SIP registration command as a first request to the telecommunication network to switch from the registration to the deregistration of the communication device responsive to the disable registration period having expired;
- and
- transitioning from the hearing mode to the teletype mode according to a response from the telecommunication network.

A non-transitory computer-readable storage device comprising executable instructions which, responsive to being executed by a processor, facilitate performance of operations comprising:
- receiving an input from a user interface requesting a transition from a hearing mode to a teletype mode;
- generating a first session initiation protocol (SIP) command for switching from registration to deregistration of a communication device at a telecommunication network responsive to the input, wherein the first SIP command initiates deregistration of the communication device when transitioning from the hearing mode to the teletype mode;
- determining whether a disable registration period has been started;
- initiating the disable registration period responsive to the disable registration period not having been started;
- determining whether the disable registration period has expired responsive to the disable registration period having been started;
- transmitting the first SIP registration command as a first request to the telecommunication network to switch from the registration to the deregistration of the communication device responsive to the disable registration period having expired;
- and
- transitioning from the hearing mode to the teletype mode according to a response from the telecommunication network.

A method, comprising:
- receiving, by a system comprising a processor, an input from a user interface requesting a transition from a hearing mode to a teletype mode;
- generating, by the processor, a first session initiation protocol (SIP) command for switching from registration to deregistration of a communication device at a telecommunication network responsive to the input, wherein the first SIP command initiates deregistration of the communication device when transitioning from the hearing mode to the teletype mode;
- determining, by the system, whether a disable registration period has been started;
- initiating, by the system, the disable registration period responsive to the disable registration period not having been started;
- determining, by the system, whether the disable registration period has expired responsive to the disable registration period having been started;
- transmitting, by the system, the first SIP registration command as a first request to the telecommunication network to switch from the registration to the deregistration of the communication device responsive to the disable registration period having expired;
- and
- transitioning, by the system, from the hearing mode to the teletype mode according to a response from the telecommunication network.
