SoundStation 5000 Unable to perform a conference

Anonymous · ‎03-08-2019

I'm experiencing an odd issue on a SoundStation 5000. When I attempt to make a conference call, the phone does not send a RE-INVITE with authentication after receivinga 401 from the UAS. Instead, it simply sends an ACK.

Call Flow:
1. UAC (Soundstation 5000) send an invite.
2. UAS (Broadworks) Challenges with a 401

3. UAC Send an ACK to UAS

4. UAC Send an invite with the Authorization headers.

5. Call is send to the network.

6. The remote party answers, and a 200 OK is sent from UAS to UAC.

7. The "conf" button is pressed on the UAC

8. The UAC send an INVITE placing the call on hold
9. The UAS replies with a 200OK

10. The UAC sends a new INVITE to the UAS.

11. the UAS challenges with a 401

12. The UAC sends an ACK.

13. 30 seconds later the UAC sends an INVITE to recover the call from being on hold.

Phone Information:

Platform: Model=SoundStation IP 5000, Assembly=3111-30900-001 Rev=H Region=0

|Platform: Board=3111-30900-001 1 0

Platform: BootBlock=3.0.4.0001 (30900-001) 11-Jul-12 08:54

|Application, main: Label=Updater, Version=Azurite 5.0.8.0935 14-Jan-15 20:29

|Application, main: P/N=3150-11069-508

SIP Application: 4.0.9.0509

What's interesting is that another IP 5000 phone that is "Rev=G" handles this call flow properly. The REv=G phone is on the same SIP load.
