Having a problem with no audio in several ways during 3-party conference call from SIP phone. System: Samsung OS7200 v 4.80, MGI16 card.
I tried with Polycom IP6000 SIP phone, as well as with basic Fanvil SIP phone - same issues (so the problem is not in SIP device).
Scenario:
SIP phone (A) dials first digital Samsung phone (B): everything OK
SIP phone presses conf button
SIP phone dials second digital Samsung phone (C): everything OK
SIP phone presses conf button to join all 3 parties to conference
A -> B ok
A -> C ok
B -> A ok
C -> A no audio!
B -> C ok
C -> B no audio!
Conclusion: phone that joined conference as last can not be heard on other two phones.
Any ideas?
...with 3 IP devices even more problems
