# Pentesting VoIP / SIP (port 5060)
## When to Use
- Default SIP ports `5060/udp` and `5060/tcp`; TLS (`sips:`) on `5061/tcp`; RTP media on negotiated high UDP ports. PBXs often also expose `69` TFTP, `80/443` web, `389` LDAP, `3306` MySQL, `5038` Asterisk Manager (AMI), `5222` XMPP.
- When `nmap` shows `5060` SIP, or you find IP phones / a PBX (Asterisk, FreePBX, Elastix, Cisco CallManager, Grandstream).
- SIP is text-based (HTTP-like: INVITE, REGISTER, ACK, BYE, OPTIONS) and frequently misconfigured, enabling toll fraud, eavesdropping, and credential theft.
## Quick Enumeration
```bash
# Locate SIP services (NSE + SIPVicious + sippts)
sudo nmap --script=sip-methods -sU -p 5060 10.10.0.0/24
svmap 10.10.0.0/24 -p 5060-5070 --fp # SIPVicious mapper (UA=friendly-scanner, easily blocked)
sippts scan -i 10.10.0.0/24 -p all -r 5060-5080 -th 200 -ua Cisco
