Dear friends in suffering from missing support by Zoho One,

I hope someone here has an idea, why ZOHO ONE / Yeastar S100 integration doesn't work properly, and how to solve this.

Sorry Phonebridge Support that I make this now public, but since I haven't heard from you since more than a month, I have no other choice.

for reference: this is about [## 458937 ##] Yeastar Phone Bridge

(I believe I was patient enough, since that is open since end of September 2023)

Status Quo:
Zoho phone bridge and Yeastar S100 show both *CONNECTED*.
The Yeastar S100 is behind a CISCO RV340. The cisco is configured according the requirements

INBOUND CALLS are fine. Popup appears, Call is recorded- perfect.

Outbound calls initiated from the CRM - stay in status Connecting... and nothing happens...

We tested the following scenarios:
1.) Outbound from desk phone (manually dialed) - working & recorded in CRM
2.) Inbound from another office phone - working & recorded in CRM
3.) Inbound from Mobile Phone number - working & recorded in CRM
4.) Outbound from ZOHO CRM - Not working, and nothing is recorded in CRM or CDR of Yeastar.

Yeastar analyzed the S100 log files and provided them to Zoho too.

NOTHING FOUND in Yeastar logs.. Not even a connection request.

Zoho replied on October 11th, that they see a timeout after 180ms while trying to connect.
But they provided no further details, and did not respond to questions from myself or yeastar support.

A meeting organized together with Yeastar - skipped by ZOHO. afterwards - no further replies.

Does anyone know on which IP address / range the Zoho phonebridge / ZOHO CRM is located in EU datacenter?

Has anyone an idea how to solve this.

BR,

Mario
