Re-registration doesn't work, it registers only once.

First time the registration occurs and it is successful. After 5 mins, it re-registers and goes to "Unregistered, Bye" state. After that nothing happens.

RFC 3261 requires UAs MUST NOT send a new registration until they have received a final response from the registrar for the previous one or the previous REGISTER request has timed out. Note that if the transport disconnects, you still must wait for the prior request to time out before sending a new REGISTER request or alternatively dispose of the current Registerer and create a new Registerer.

Any updates?

The same issue exists in SIP.js v0.13.5, and it is currently suspected that this may be due to unexpected behavior of timers (registrationTimer and registrationExpiredTimer).

Relevant code: https://github.com/onsip/SIP.js/blob/0.13.5/src/RegisterContext.ts#L296

Is it possible for you to provide an API for custom timer functions?

For example, APIs like externalSetTimeout and externalClearTimeout.
