Single CUBE - multiple ITSPs

[Ruterford]

Hi Everyone,

I am wondering if single CUBE router can be used to terminate multiple ITSP SIP trunks.

I will be using multiple authentications under  sip-ua.

Thanks

You should be able to do that. Refer to below:

Configuring Multiple Registrars on SIP Trunks

---

The Support for Multiple Registrars on SIP Trunks on a Cisco Unified Border Element, on Cisco IOS SIP TDM Gateways, and on Cisco Unified Communications Manager Express feature allows configuration of multiple registrars on Session Initiation Protocol (SIP) trunks, each simultaneously registered using their respective authentication instance. This feature allows a redundant registrar for each of the SIP trunks, which provides SIP trunk redundancy across multiple service providers.

There is a configuration example as well, look into it and see if it resolves your query.
