Webex Hybrid Call Service - Calls from Webex to On Premise fail

ggmr1
Level 1
Level 1

Hello,

 

I am deploying a Webex Hybrid Call Service following this guide: Guide

I already made succsessfull calls from CUCM registered phones to Webex Teams users but inbound calls are failing.

Reviewing Expressway's E Event Log, I get these registers:

 

2019-03-04T11:13:05.044-04:00 tvcs: Event="Call Rejected" Service="SIP" Src-ip="18.221.216.175" Src-port="18044" Src-alias-type="SIP" Src-alias="sip:user.name@mydomain.call.ciscospark.com" Dst-alias-type="SIP" Dst-alias="sip:4156@cucm.mydomain.bo;user\=phone" Call-serial-number="78b84332-75e1-4087-96dc-63b597844cce" Tag="39e60b26-c375-482c-88cd-a94ac3d13543" Detail="Not Found" Protocol="TLS" Response-code="404" Level="1" UTCTime="2019-03-04 15:13:05,044"

Y already reviewed frewall ports and all the configurations is like the guide instructs.

 

I will appreciate your help resolving this issue.

 

Thanks.
