I’m encountering a strange issue when trying to transfer/place calls on hold via GS Wave. When the phone is connected to local wifi, and is registering via the local account, hold key functionality works fine; I press hold, hold music is heard by the other party, and I can take the call off hold when I’m ready.
However, when I try the same setup, but connected via the external account, the hold key does not work. When pressed, the other caller hears only silence. What’s more, pressing the hold key again does not retrieve the call; it is left in limbo until the connection times out.
Is this a known issue, or is there a workaround? Audio and SIP streams between the softphone and PBX are fine, during a normal call both parties can hear eachother without problems.
