What could be the concern for one way calling issue between IP communicator & PSTN
cust when using the IPC thru his WAN connection( MPLS cloud) or Wifi connection when in office located in Russia to UK;cust has one way calling issue
When he connects VPN secure Client R56 NG, which has secured tunnel till UK where callmanager,GW r placed then customer still complains for one way calling issue for PSTN Line
Now when cust access thru UK location, then he donot have one way calling issue with PSTN
Note: When customer tried in Russia office, then his other colleague aslo tried,his collegaue hsd similar issue.
Could upgrading the VPN client to latest version could be helpful? or do i need to check the configuration on GW side, as since i donot have access to GW so i need proper justification to get it, pl suggest
