mumsi - SIP to Mumble gateway
SIP to Mumble gateway based on PJSIP stack and mumlib library. It registers to SIP registrar and listens for incoming connections on the SIP account.
This enables the user to participate in Mumble conference using SIP client or perhaps ordinary telephone, by VoIP provider.
- Boost libraries
- pjsua2 from Pjproject SIP stack
- mumlib - https://github.com/slomkowski/mumlib
Build and usage
Install all needed dependencies
Clone and compile Mumlib library. Since it doesn't have any installer, clone it to common directory:
mkdir mumsi-dist && cd mumsi-dist git clone https://github.com/slomkowski/mumlib.git mkdir mumlib/build && cd mumlib/build cmake .. make cd -
- Then clone and build mumsi:
git clone https://github.com/slomkowski/mumsi.git mkdir mumsi/build && cd mumsi/build cmake .. make
- Copy example config.ini file and edit it according to your needs:
cp config.ini.example config.ini
Remember to add URIs which you want to make calls from. Calls from other URIs won't be answered.
- To run the service, type:
Start at boot
mumsi provides no init.d scripts, but you can use great daemon mangaer, Supervisor. The sample configuration file:
[program:mumsi] command=/home/mumsi/mumsi-dist/mumsi/build/mumsi config.ini directory=/home/mumsi/mumsi-dist/mumsi user=mumsi stdout_logfile=/home/mumsi/console.log stdout_logfile_maxbytes=1MB stdout_logfile_backups=4 stdout_capture_maxbytes=1MB redirect_stderr=true
Port and NAT
Remember to allow incoming connections on port 5060 UDP in your firewall. If you're connecting to public SIP provider from machine behind NAT, make sure your setup works using some generic SIP client. Since SIP is not NAT-friendly by design, PJSIP usually takes care of connection negotiation and NAT traversal, but might fail. The most reliable solution is to configure port forwarding on your home router to your PC.
You may encounter following error when running mumsi on older distros
pjsua_conf_add_port(mediaPool, (pjmedia_port *)port, &id) error: Invalid operation (PJ_EINVALIDOP)
Some older versions of PJSIP are affected (confirmed for 2.3). In this case you have to update PJSIP to most recent version (2.4.5).
- multiple simultaneous connections
- outgoing connections
- text chat commands
