I have an Openscape X3R with SIP trunks.
Call scenario:
Call comes into site and is answered on a Openstage 40 HFA, Caller put on hold by Openstage 40, mobile number is dialled and Openstage 40 hangs up to transfer call. Screen on Openstage 40 says call transferred but there is one way speech and sometimes no speech atall but the call remains connected.
If mobile is replaced by a landline number the issue doesn't occur. The issue appears to be when doing a trunk to trunk transfer to a mobile.
