Scenario:
Have 3Com NBX100 VOIP NBX System located in corprate office. Each remote site A and B are linked thru Sonicwall TZ170 VPN using T1 line to the corprate office. Each site have at least 3 3COM phone stations. VPN tunnells are sharing datas as well as voice.
Problems:
When site A initiating a call to site B's phone extension, can hear site B but site B can't hear site and vice versa when Site B initiatin a call to Site A's phone extension; but there is no problem to call to corporate office except sometimes the sounf quality is not good and can only hear one way communication.
Does anyone has this kind of problems? Please help. Thank you.
