when my system in called, the caller hears no ring back. Just dead air until someone answers. I worked with my sip provider support and what’s happening is that my system is sending both a 183 Session Progress and a 180 Ringing.
This would cause issues as the 183 states the equipment is going to be sending early media but then the 180 indicates the system is not expecting to send media.
is there a setting somewhere in the FreePBX gui or a CLI command in asterisk to change this behavior?
I have noted the recent reports, and have tested but have so far been unable to reproduce this, probably because it is provider specific. Thread offers a clue to the issue:
Almost all reports I have seen were google voice issues fixed by changing the codecs (putting gsm at the top)
“Ringing indication” can be turned off in inbound routes.
I have not had these issues no matter what settings I toggle and I don’t use google voice outside of their AUP or through back doors so I can’t say what will or won’t work for them
James I had this issue before rolling back the ring group module and it was on purely internal calls (no trunk was in play). It could only be issue with some endpoints not all, really not sure. I would test it more if I could but too much on my plate at the moment.
