# Cisco CUBE / CallManager Express Configuration

The following is to help with the connection of Cisco CUBE or CallManager Express to our environment.

## Why this article matters

Network engineers operating Cisco Unified Border Element (CUBE) routers or CallManager Express deployments typically reach this guide when integrating a Cisco-anchored voice infrastructure with an Australian SIP carrier. The configuration references the Simtex carrier IP ranges (203.30.19.164/32 and 203.32.124.160/27) for the voice service VoIP trusted IP list and uses UDP dial peers with appropriate codec and DTMF settings — a topology that aligns with Cisco's recommended CUBE deployment patterns for ITSP-facing trunks. The service referenced is Simtex SIP Trunks, priced from $4.99 per channel per month and delivered from geo-redundant Perth and Sydney points of presence on a 99.99% uptime SLA. The trunk supports IP-authenticated topologies suitable for CUBE deployments, removing the need for per-trunk registration credentials in environments where the SBC posture is preferred. Cisco-anchored Australian voice deployments are typically evaluated against incumbent SIP Connect services from Telstra Business and Optus, and against reseller providers such as Vonex and Maxotel. Direct carrier ownership, transparent per-channel pricing, and Australian-based engineering support familiar with Cisco IOS voice configuration are the points of difference. The same Simtex carrier account can also terminate to Microsoft Teams via Simtex Teams Direct Route if the organisation is parallel-running Cisco and Teams calling.

## Overview

Configuration reference for connecting Cisco CUBE or CallManager Express to the Simtex SIP trunk environment over UDP. Adjust dial peers to suit your deployment.

> **Info:**
> **SIP Server:** `sip.simtex.com.au` (UDP) &mdash; SRV-enabled for automatic failover.

## Voice Service & Global Config

```
`voice service voip
 ip address trusted list
  ipv4 203.30.19.164 255.255.255.255
  ipv4 203.32.124.160 255.255.255.224
  ipv4 202.74.176.160 255.255.255.240
  ipv4 202.74.176.176 255.255.255.248

```

## Translation Rules & Profiles

```
`! Apply calling number (Caller ID) - use your DID in E.164
voice translation-rule 1111
 rule 1 /.*/ /61894883344/

! Strip leading 0 for outbound calls
voice translation-rule 1112
 rule 1 /^0/ //

voice translation-profile Remove_0Prefix_ApplyCLID
 translate calling 1111
 translate called 1112`
```

> **Tip:**
> Replace `61894883344` with your own DID in E.164 format (without the +).
