Simply try some echo test numbers, like pennytel's 888123456 or iptel's 3246. Just get the ring signal doesn't mean the audio is OK.作者: siriusw 時間: 2013-7-19 01:25
剛剛試過用電話經Dlink打PennyTel的support hotline 777 (voice system) 係ok的, 聽得好清楚。
但問題係:
我有2個PennyTel account: Acc A & Acc B
Acc A set左落Dlink
Acc B set左落X-Lite (Mac)
Acc A 打 Acc B, 會響, 但接左無聲。
Acc B 打 Acc A, 一樣會響, 但一樣接左無聲。
It depends on your VSP, i.e., pennytel. If pennytel does NOT allow two accounts from the same ip address, you can only chnage to another VSP that support 2acc.@one ip.
If pennytel allows 2acc.@one ip, your problem could be the NAT problem.
