Troubleshooting Common Issues in Boghe IMS/RCS ClientBoghe is a lightweight SIP/IMS and RCS softphone designed for desktop environments (Linux and Windows). It offers basic voice, messaging, and presence features while integrating with IMS networks and supporting RCS flows where implemented. Despite its simplicity, users can encounter a variety of problems related to configuration, network, audio, and interoperability. This article walks through systematic troubleshooting steps, common causes, and practical fixes to get Boghe running smoothly.
1. Preparation: Gather diagnostic information
Before troubleshooting, collect essential information. This speeds diagnosis and avoids guesswork.
- Boghe version and build date.
- Operating system and version (e.g., Ubuntu 22.04, Windows 10).
- SIP/IMS/RCS server details (S-CSCF, P-CSCF, home domain).
- Transport protocol in use (UDP/TCP/TLS).
- Network environment: behind NAT, using VPN, mobile network, or public IP.
- Any relevant logs or console output from Boghe.
- SIP trace (e.g., pcap) if available.
Having these will help you or a support engineer pinpoint where the problem lies.
2. Installation and startup failures
Symptoms: Boghe fails to start or crashes immediately.
Checks and fixes:
- Verify system requirements. On Linux ensure required shared libraries (GTK, glib, libsofia-sip, etc.) are installed.
- Run Boghe from a terminal to capture stdout/stderr messages and stack traces.
- Reinstall or try a different build (32-bit vs 64-bit) matching your OS.
- If crash occurs on startup, check for corrupted configuration files—rename or move the Boghe config directory to force a fresh configuration on next launch.
3. Registration problems (SIP/IMS/RCS registration fails)
Symptoms: Boghe shows “Not Registered”, or registration intermittently fails.
Common causes and solutions:
- Incorrect credentials: Double-check Private Identity (IMPI), Public Identity (IMPU), and password. IMS needs specific formats (e.g., IMPU like sip:username@domain).
- Wrong SIP/IMS proxy (P-CSCF/S-CSCF) or Outbound proxy settings. Ensure the FQDN/IP and port are correct.
- Transport mismatch: Ensure the server expects UDP/TCP/TLS and configure Boghe accordingly. For IMS, TLS is often required.
- DNS resolution: If using FQDNs, ensure DNS resolves correctly. Try pinging or using dig/nslookup.
- Firewall/NAT blockage: SIP signaling may be blocked by firewalls or port-restricted NAT. Open required ports or use TLS/TCP to traverse firewalls.
- Missing or invalid TLS certificate: If using TLS, verify certificate chain. For self-signed server certs, add the CA to the OS store or allow insecure connections only if acceptable.
- SIP realm mismatch: Some IMS networks require realm matching in authentication; ensure realm is set as required.
- Network access control: IMS networks can enforce IP whitelisting. Confirm the client’s IP is allowed or use a VPN as required.
- IMS-specific: Ensure correct S-CSCF assignment and that user is provisioned in the HSS/PLMN subscription.
Diagnostics:
- Enable SIP/IMS trace in Boghe and inspect REGISTER requests and ⁄407 responses.
- Look for WWW-Authenticate/Proxy-Authenticate headers to confirm realm and nonce behavior.
- Capture pcap of registration flow to inspect network-level issues.
4. Call setup failures and one-way audio
Symptoms: Calls fail to connect, are dropped, or audio is one-way/absent.
Checklist and fixes:
- SDP/Codec mismatch: Verify supported codecs on both sides. Ensure at least one common codec (e.g., OPUS, G.711). Adjust codec preference order if necessary.
- NAT traversal and RTP: One-way audio usually indicates RTP packets blocked by NAT/firewall. Use ICE/STUN/TURN if supported. Configure STUN server in Boghe if behind NAT.
- RTP port ranges: Ensure RTP port range used by Boghe is not blocked. Open those ports on the firewall/router or use symmetric RTP.
- Media transport mismatch: If server expects SRTP and client sends RTP, media won’t establish. For secure media, enable SRTP and provide keys/certs as required.
- Mismatched media IP: When SDP contains a private IP because of NAT, the far end will try to send RTP to that unreachable address. Use NAT traversal features or a media relay (TURN) to fix this.
- Packet inspection or SIP Application Layer Gateway (ALG): Some routers have SIP ALG that modifies SIP/SDP and breaks flows—disable SIP ALG if possible.
- Audio device selection: Ensure the correct microphone/speaker device is selected in Boghe. Check system sound settings and test with other apps.
- Volume and mute: Confirm Boghe and OS levels aren’t muted.
Diagnostics:
- Inspect INVITE/200 OK SDP payloads to verify media IPs and ports and codecs.
- Use Wireshark to observe RTP streams and identify where packets stop.
- Run a loopback or local media test if Boghe offers it.
5. Messaging and RCS issues
Symptoms: SMS/IM or RCS messages fail to send, are not received, or appear out of order.
Common causes and remedies:
- IMS/RCS service provisioning: Ensure user is provisioned for RCS on the operator’s platform. RCS often requires server-side configuration and capabilities exchange.
- SIP MESSAGE vs. MSRP vs. MSRP relays: RCS may use MSRP for rich messages. If Boghe is configured for MESSAGE over SIP but network expects MSRP, messages won’t flow. Confirm the messaging transport and enable MSRP if supported.
- Firewall/NAT blocking MSRP/TCP flows: Open necessary TCP ports or use an MSRP relay if provided by the operator.
- Capability discovery: RCS uses capability exchange (e.g., via XCAP or presence). Ensure presence/capability services are reachable and correctly configured.
- Conversation state sync: RCS sessions may require specific SIP headers (P-Asserted-Identity, etc.)—ensure Boghe includes required headers.
- Charset and content-type mismatches: Verify correct content-types and character encodings for messages.
Diagnostics:
- Capture signaling for MESSAGE or MSRP sessions to see where failures happen and what response codes appear.
- Check presence and capability responses.
6. Presence and buddy list not updating
Symptoms: Contacts show offline or presence does not update.
Fixes:
- Presence server config: Confirm presence server URI and credentials (if separate from IMS registration).
- SUBSCRIBE/NOTIFY flow: Inspect SUBSCRIBE requests and NOTIFY responses. Some deployments require specific headers (Event, Expires).
- Authorization and privacy rules: Presence may be blocked by privacy lists on the server—verify subscription permissions.
- Polling vs push: If Boghe uses polling for presence but server expects push, reconfigure accordingly.
Diagnostics:
- Enable presence-related logs and check server responses to SUBSCRIBE.
- Verify expiration times and refresh behavior.
7. Interoperability with specific IMS/RCS networks
Symptoms: Works with some providers but not others.
Troubleshooting approach:
- Compare successful vs failing provider traces—look for differing 4xx/5xx responses, header requirements, or transport expectations.
- Review operator-specific provisioning: Many carriers require device/user provisioning, special headers (e.g., P-Access-Network-Info), or specific TLS ciphers.
- Check for SIP extensions: Some operators require P-Asserted-Identity, P-Visited-Network-ID, or other custom headers—ensure Boghe can add or pass these headers.
- Certificate pinning or mutual TLS: Some networks require client certificate authentication. Configure client certs if required.
8. Security and certificate issues
Symptoms: TLS handshake failures, certificate verification errors, or authentication rejected.
Fixes:
- Time/date mismatch: Ensure system clock is accurate; TLS validation depends on correct time.
- CA chain: Install the operator’s CA or intermediate certificates in the OS trust store if using self-signed or private CA.
- Inspect TLS logs: Look for SNI mismatches, unsupported ciphers, or protocol version issues. Enable TLS debugging if available.
- Mutual TLS: If required, import client certificates and private keys into Boghe, and configure the client to present them during TLS handshake.
9. Performance problems (high CPU, memory leaks, lag)
Causes and mitigations:
- Background tasks: Presence and frequent capability polling can consume CPU. Reduce polling frequency where possible.
- Large buddy lists or heavy message history: Trim history or limit synced contacts.
- Outdated build: Update to the latest stable release where memory leaks or bugs might have been fixed.
- System resource conflicts: Check for other apps using audio devices or excessive disk I/O.
Diagnostics:
- Use system monitoring tools (top, Task Manager) to identify resource hogs.
- Run Boghe under a profiler or with debug logging enabled if suspecting leaks.
10. Logging and debugging tips
- Increase Boghe’s log verbosity in settings when diagnosing issues; revert to normal after gathering evidence.
- Save logs and relevant pcap captures. Annotate them with timestamps and expected behavior so others can review.
- Reproduce issues in a controlled environment where you can change one variable at a time (network vs local, different codecs, with/without TLS).
- When contacting support, include: version, OS, network type, config screenshots, SIP traces, and any error response codes.
11. Quick-reference checklist
- Credentials and IMS identities correct (IMPI/IMPU).
- Correct proxy, port, and transport (UDP/TCP/TLS).
- TLS certificates trusted and system time correct.
- NAT traversal: STUN/TURN/ICE or media relay configured.
- Codecs match and SRTP vs RTP settings aligned with server.
- Firewalls and SIP ALG disabled or configured properly.
- Presence/messaging services provisioned by operator.
- Client updated to latest stable version.
12. When to involve operator or developer support
Contact the network operator if:
- Registration responses indicate subscriber provisioning issues (e.g., 403 Forbidden with operator messages).
- The operator requires provisioning, client certificates, or uses proprietary headers.
Contact Boghe developers or community if:
- You find application crashes, reproducible bugs, missing features, or unclear behavior that can’t be fixed by configuration.
- You can provide logs, SIP traces, and steps to reproduce.
Troubleshooting Boghe involves a methodical approach: verify credentials and network settings, examine signaling and media flows, account for operator-specific requirements, and collect detailed logs. With these steps you can resolve the majority of registration, call, and messaging issues or gather the evidence needed for operator/developer support.
