pjsua2-wheel 2.15.3

Pre-built Windows wheels for PJSUA2 with bundled VC++ Runtime - Python bindings for PJSIP (SIP/VoIP Library)

PJSUA2-Wheel - Standalone Windows Wheels for PJSIP

Truly standalone Windows wheels for PJSUA2! 🎉

This package provides pre-compiled Windows wheels for PJSUA2 (Python bindings for PJSIP) with bundled Visual C++ Runtime DLLs. No additional installations required - just pip install and start coding!

Note: This is a community-maintained wheel distribution. For the official source package, see pjsua2 on PyPI.

What's New in 2.15.3

✨ Standalone Wheels - All required Visual C++ Runtime DLLs are now bundled!
✨ No VC++ Redistributable needed - Works on clean Windows systems
✨ Standard Import - Use import pjsua2 (not pjsua2_standalone)
✨ Fixed Import Issues - Resolved module loading problems from 2.15.2
✨ Optimized Size - Wheel size (~2.7 MB)
✨ Python 3.9-3.12 support - Wheels for all modern Python versions

Windows (Pre-built wheels!)

pip install pjsua2-wheel

No compilation required! The wheel includes everything you need:

• ✅ Pre-compiled PJSIP libraries
• ✅ Bundled Visual C++ Runtime DLLs
• ✅ No Visual Studio required
• ✅ No VC++ Redistributable installation needed

Package name: pjsua2-wheel (for pip install)

See PJSIP documentation for details.

Features

✅ Audio/Video Calls - HD voice and video support
✅ Media Handling - Codecs, RTP/RTCP, jitter buffer
✅ NAT Traversal - STUN, TURN, ICE support
✅ Secure Communications - TLS, SRTP encryption
✅ Conferencing - Audio mixing and conferencing
✅ IM & Presence - Instant messaging and presence

Quick Start

import pjsua2 as pj

# Create and initialize endpoint
ep = pj.Endpoint()
ep.libCreate()

ep_cfg = pj.EpConfig()
ep.libInit(ep_cfg)

# Create SIP transport
sipTpConfig = pj.TransportConfig()
sipTpConfig.port = 5060
ep.transportCreate(pj.PJSIP_TRANSPORT_UDP, sipTpConfig)

# Start the library
ep.libStart()

print(f"PJSIP {ep.libVersion().full} started!")

# Your SIP application code here...

# Cleanup
ep.libDestroy()

Example: SIP Registration

import pjsua2 as pj

class MyAccount(pj.Account):
    def onRegState(self, prm):
        ai = self.getInfo()
        print(f"Registration: {ai.regStatusText}")

# Configure account
acc_cfg = pj.AccountConfig()
acc_cfg.idUri = "sip:[e-mail]"
acc_cfg.regConfig.registrarUri = "sip:example.com"

# Add credentials
cred = pj.AuthCredInfo()
cred.scheme = "digest"
cred.realm = "*"
cred.username = "user"
cred.dataType = pj.PJSIP_CRED_DATA_PLAIN_PASSWD
cred.data = "password"
acc_cfg.sipConfig.authCreds.append(cred)

# Create account
acc = MyAccount()
acc.create(acc_cfg)

Example: Making a Call

class MyCall(pj.Call):
    def onCallState(self, prm):
        ci = self.getInfo()
        print(f"Call state: {ci.stateText}")

# Make a call
call = MyCall(account)
prm = pj.CallOpParam()
call.makeCall("sip:[e-mail]", prm)

Building from Source

If pre-built wheels aren't available for your platform:

Requirements:

• C++ compiler (GCC, Clang, or MSVC)
• SWIG 4.x
• Python development headers

Linux/macOS:

git clone https://github.com/pjsip/pjproject.git
cd pjproject
./configure CFLAGS="-fPIC"
make dep && make
cd pjsip-apps/src/swig
make
cd python
make && make install

Windows:

See Windows build guide

Troubleshooting

Import Error on Windows

# Make sure you have Visual C++ Redistributable
# Download from: https://aka.ms/vs/17/release/vc_redist.x64.exe

Audio Issues

# List available audio devices
ep = pj.Endpoint()
ep.libCreate()
ep_cfg = pj.EpConfig()
ep.libInit(ep_cfg)

audDevManager = ep.audDevManager()
devCount = audDevManager.getDevCount()
for i in range(devCount):
    info = audDevManager.getDevInfo(i)
    print(f"Device {i}: {info.name}")
