Alianza One BCC — Target Platform

Connects CCaaS to Alianza One (BCC) by creating a SIP Trunk in the Alianza One portal and entering its SIP proxy and call capacity details in CCaaS.

Alianza One (Business Cloud Communications, or BCC) connects to CCaaS through a SIP Trunk created in the Alianza One portal. The trunk defines how many simultaneous calls can pass between the two platforms and provides the SIP Proxy Server that CCaaS registers against. This must be completed before the trunk's SIP credentials can be registered — see SIP Extensions.

Adding the SIP Trunk Product

Sign in to the Alianza One portal
Scroll to the bottom of the left-hand navigation pane and select Settings
Navigate to Account Details > Products and select + Add Product
In the Add Product window, select SIP Trunk
A confirmation banner displays once the SIP Trunk product is added

Creating the SIP Trunk

Select SIP Trunk from the left-hand navigation pane
Select + Add SIP Trunk in the top-right corner of the SIP Trunks page
Complete the following fields:

Field	Description
Trunk Name	The name of the trunk (for example, `Xima Contact Center`)
Language	The language used for the trunk
911 Callback Number	The callback number presented for emergency calls
Primary Phone Number	The primary phone number associated with the trunk
Number of Dialing Digits	How many digits pass back and forth on the trunk — `7-Digits`, `10-Digits`, or `11-Digits`

Configuring Failover Routing

✅
Strongly Recommended
Failover routing is not required at initial setup, but Xima strongly recommends configuring both destinations below in case the SIP Trunk to Xima is busy or goes down.

Section	Description
Overflow Routing	Where calls go when the SIP Trunk reaches capacity; select `+ Add Overflow SIP Trunk` to add a trunk, and set `Forward on Overflow` for when all trunks are at capacity
Inbound Failover Routing	Where calls go when the SIP Trunk fails; select `+ Add Failover SIP Trunk` to add a trunk, and set `Forward on Failure` for when all trunks fail

Setting Concurrent Calls

Concurrent Calls Allowed defines the total number of simultaneous conversations ("talk paths") between Alianza One and CCaaS.

Under Definition, enter a value for Concurrent Calls Allowed
Note this value — it is entered as Max Calls per Handset in CCaaS
Select Create
The new trunk is listed on the SIP Trunks page with its Concurrent Calls Allowed value (for example, Xima Contact Center with 30)

Noting the SIP Proxy Server

Select the new trunk on the SIP Trunks page to expand its details
Under Authentication Credentials, note the SIP Proxy Server value — it is entered as the SIP Domain in CCaaS

The SIP Username and SIP Password in this same section are configured separately — see SIP Extensions.
