$50,000 stupid kagege.
No video ghaseer
Too lazy to click through and he wants to watch a video on Cisco migration/configuration.

Leta ya Cisco VoIP configuration
Try doing it yourself elder.
I. Required Equipment
1. Core Networking Hardware
- Cisco Routers (for WAN connectivity and voice gateways)
- Cisco Switches (preferably PoE – Power over Ethernet – to power IP phones)
- Cisco Firewalls (e.g., ASA or Firepower for network security)
- Voice Gateways (e.g., Cisco ISR 4000 series for PSTN integration)
2. Endpoints
- Cisco IP Phones (e.g., 8800 series, 7800 series)
- Softphones (Cisco Jabber, Webex App, or 3rd party SIP clients)
3. Server Infrastructure
- Cisco Unified Communications Manager (CUCM) – the call control server
- Cisco Unity Connection – for voicemail and auto-attendant
- Cisco Unified Presence / IM&P – for presence and instant messaging
- Cisco Unified Contact Center Express (UCCX) – if call center features are needed
- Cisco Emergency Responder (optional but recommended for large sites)
4. Ancillary Components
- DHCP & DNS Servers – for IP assignment and name resolution
- NTP Server – for clock synchronization across devices
- TFTP Server – for phone configuration file delivery (usually built into CUCM)
- Certificate Authority – for secure SIP/TLS deployments
II. Installation & Configuration Steps
1. Network Preparation
- Verify IP addressing, VLANs, and QoS readiness (voice VLANs separate from data).
- Configure switch ports for PoE and VLAN assignment for phones (
switchport voice vlan X). - Ensure routing between voice subnets and CUCM network is operational.
2. Server Deployment
- Install CUCM and other Unified Communications servers (Unity, Presence) on Cisco UCS or VMware ESXi hosts.
- Configure IP addresses, DNS, NTP, and network interfaces.
- Apply necessary Cisco licenses (Smart Licensing).
3. Call Manager Configuration
- Create Device Pools, Regions, and Locations for call routing control.
- Configure Phone Templates, Device Profiles, and User Accounts.
- Add IP Phones (auto-registration or manual MAC entry).
- Set up Directory Numbers (DNs) and assign extensions to users.
4. Gateway and PSTN Integration
- Configure SIP Trunks, H.323, or MGCP Gateways to connect to the PSTN.
- Set up Dial Peers and Route Patterns for outbound/inbound call routing.
- Test PSTN connectivity with test numbers.
5. Voice Features
- Configure Voicemail (Unity Connection) and link it to CUCM via SIP.
- Set up Call Forwarding, Hunt Groups, Auto-Attendant, and IVR if required.
- Configure Presence and Instant Messaging through IM&P or Webex.
6. QoS & Security
- Enable QoS policies on routers and switches to prioritize RTP (voice) traffic.
- Implement SRTP (Secure Real-Time Protocol) and TLS for call encryption.
- Apply VLAN ACLs and firewall rules to protect voice subnets.
7. Testing and Optimization
- Register sample phones and test internal/external calls.
- Verify codec negotiation (G.711, G.729, etc.).
- Check jitter, latency, and packet loss using Cisco tools or
RTMT(Real-Time Monitoring Tool).
8. Monitoring and Maintenance
- Set up Cisco Prime Collaboration or Webex Control Hub for monitoring.
- Schedule regular backups of CUCM configuration.
- Monitor CDR (Call Detail Records) for call analytics and troubleshooting.
