Hello everyone, I have a problem with MOH and call transfer, I’ll explain better:
- secretary sip B calls secretary sip C;
- secretary sip B transfers with waiting and calls director sip A;
- secretary sip C transfers with waiting and calls director sip D;
- secretary sip B hangs up by transferring the director sip A on the channel of the secretary sip C.
At this point, in a totally random manner, the director sip A sometimes does not hear the MOH when the secretary Sip C is still talking to the director sip D.
The tests that gave these alternate results were performed with:
asterisk 1.8
asterisk 11
asterisk 13
asterisk 15
on both virtual and physical servers with OS centos ver. 6X and 7X and fedora ver.27
with terminals:
snom 710 and 720
polycom vvx 600
x-lite softphone, microsip, zoiper
the sip and pjsip protocols were used in the tests.
Has this problem ever happened to you? is there a “bug” or a case documented for this problem?
thanks to all
