ECAS Adds Incorrect Reason Header In BYEs When DE Releasing Call (Doc ID 2593389.1)

Last updated on AUGUST 24, 2020

Applies to:

Oracle Communications Evolved Communications Application Server - Version 7.1.0 to 7.1.0 [Release 7.1.0]
Information in this document applies to any platform.

Symptoms

On : 7.1.0 version, Installation and Initial Setup

When destination endpoint (DE) releases a call, it sends a SIP BYE message.
This message arrives to ECAS (Evolved Communications Application Server) and ECAS sends it towards initiating endpoint (IE).

Even this is a normal release, ECAS is adding the following header to BYE towards IE.

ERROR
--------------------------------------------------
Reason: TEMPORARILY_UNAVAILABLE


This is incorrect because it's a normal release initiated by the endpoint.
This is impacting iOS devices - display an "error" to calling when this release is received due to this header (making user think something is wrong when it's not the case).

Expected behavior is:

- ECAS shall be propagating headers in BYE to IE as they come in BYE to DE (except the ones normally changed due to B2B behavior, i.e. Contact, To/From tags etc).

- That is, no error Reason shall be added. If a Reason comes from the DE, shall be kept as it is (as any other header coming from the DE except the ones B2B related).
