The call disconnects with message "Call End" when making transfer Highlighted

Hello, team!

Have a nice day!

This post describes how to deal with the problem that the call disconnects with the message "Call End' when making a transfer.

Issue Description

Unable to transfer outgoing calls to any user(Extensions) from the IP Phones. But the incoming calls can be transferred.

For Example

An internal user-A calls the external user-B, and then internal user A transfers the call to internal user C. Then the call disconnects with the message "Call End".

eSpace 8950 version: V200R003C30SPCh10

Network Topology

Note

The customer is using the USM Server on which the IP Phones are registered, and U19 is just working as a voice gateway.

Handling Process

We asked the customer to activate call transfer on the user as follows:

1. Log in the web management system of a U1900 and on the User > SIP User, select the user number to be assigned the service permission and click Service Configuration.
   

2. Under Simple service, select the service to activate and click OK.

• After that, we asked the customer to make a test but the issue didn't solve.

• We asked the customer to enter this command on U19: config softargu type 362 value 1

• We asked the customer to make a test again, then it became able to transfer outgoing calls to any user.

Solution

Enter this command on U19: config softargu type 362 value 1

That is the solution, thanks for reading!
