Happy to help, but you need to be more specific. To say "encountered issues with Linphone connectivity" is like me saying to you "My car engine won't start, what could be wrong?"
Try to get a packet capture of the connection attempt, sngrep is a good tool. Is there anything in the Freeswitch logs or the Linphone logs?
Try connecting to the freeswitch console, set log level to debug and then watch what happens when the Linphone tries to connect.
