I have E20 Tandberg version TE-4.1.1, register with sip it can send and receive outbound calls,
When i try local call 7911,7965,7945,9971 ip telephone i can not hear voice,
Therefore,When i calls local ip phone one way voice problem, but outbound calls working normally
Thanks a lot,
Check that their is both way IP routing between the VLAN for the IP phones and the VLAN for the Tandberg.
