There are two SIP channel drivers in Asterisk 15. The chan\_sip channel driver does not support PRACK. The chan\_pjsip one does. ---

Asterisk 15 makes PJSIP available automatically, unless you explicitly disable it using “make menuselect”. There are also instructions on the wiki[1] for how to set it up and other things.

They both can’t use the same port, but chan\_sip can be configured to use a different port (such as 5070). ---

No, chan\_pjsip is already built. You just have to configure things. ---

I have already provided a link to the wiki for configuring PJSIP. It includes examples and other things. For configuring chan\_sip you need to look at the sample file and see where the port can be set. ---

hi John where to load this module chan\_pjsip . could you please help me **module.conf** : Asterisk configuration file ; ; Module Loader configuration file ; [modules] autoload=yes ; ; Any modules that need to be loaded before the Asterisk core has been ; initialized (just after the logger has been initialized) can be loaded ; using ‘preload’. This will frequently be needed if you wish to map all ; module configuration files into Realtime storage, since the Realtime ; driver will need to be loaded before the modules using those configuration ; files are initialized. ; ; An example of loading ODBC support would be: ;preload =\> res\_odbc.so ;preload =\> res\_config\_odbc.so ; ; Uncomment the following if you wish to use the Speech Recognition API ;preload =\> res\_speech.so ; ; If you want Asterisk to fail if a module does not load, then use ; the “require” keyword. Asterisk will exit with a status code of 2 ; if a required module does not load. ; ; require = chan\_sip.so ; If you want you can combine with preload ; preload-require = res\_odbc.so ; ; If you want, load the GTK console right away. ; noload =\> pbx\_gtkconsole.so ;load =\> pbx\_gtkconsole.so ; load =\> res\_musiconhold.so ; ; Load one of: chan\_oss, alsa, or console (portaudio). ; By default, load chan\_oss only (automatically). ; noload =\> chan\_alsa.so ;noload =\> chan\_oss.so noload =\> chan\_console.so ; [Next page](https://community.asterisk.org/t/prack-100rel-support/74063.md?page=2)
