Jabber Softphone Incoming Call error cause 1459617833 (CCM_SIP_503_SERVICE_UNAVAILABLE)

[BorisRus]

Good afternoon.

This problem occurs in Cisco Jabber
when connecting a softphone and not a landline phone.

Incoming calls to this number SoftPhone issues cause 1459617833 - CCM_SIP_503_SERVICE_UNAVAILABLE.

 
At the same time Outgoing calls from Softphone to any number successfully pass.

Help me understand why this is happening?

[Chris Deren]

What is the Jabber soft phone registered to? CUCM, CME, something else?

[BorisRus]

Hi, Chris.
CUCM 10.5.2
Soft phone CSF (Product Type:Cisco Unified Client Services Framework)
Active Load ID: Jabber_for_Windows-12.0.1.63173

Can you provide sip traces/debugs

you can also run wireshark on the client to get the SIP messaging on the machine that has Jabber installed.

[BorisRus]

WireShark traffic with an incoming call to the client does not reach anything.

With the outbound I see the SIP Message. (attach screenshot WireShark SIP Messege)

I also attach screenshots of CDR CUCM and Traces CUCM (Incoming and outbound calls)

Blocked Antivirus.
When added to exceptions, everything worked.
