FPBX has a SIP trunk (working) …
Incoming calls are set to be answered by a ring group (with about 18 endpoints)
The calling party gets NO ringing sound when calling in.
**All 18 endpoints ring: but can only answer if they answer on the 1st ring only
Then: using module admin;
We updated the ring group module to: 126.96.36.199
Before the update:
incoming calls: caller heard no ringing
endpoints: If they did not answer on the 1st ring: they could not pickup the calls (only if they got the incoming call on its 1st ring)
After the update:
incoming calls: caller hears no ringing
endpoints: They are ringing and can now answer on any ring
NOTE: the upgrade to ring group module: fixed this …
Also (just to test and see):
If we do not use a ring group for the destination
incoming calls: caller hears the ringing sound
endpoints: delivering to a single extension (they can pickup on any of the rings)
So, for some reason: if we deliver to a ring group: the calling party does not hear any ringing while they call into the PBX (even from a cell phone).
Thanks for your tips.
