I bought The Sangoma PHS-500 box(FreePBX 13.0.119 'VoIP Server') and have connected it to the new Audiocodes median500 MSBR (Firmware Version 6.60A.292.001).
And From Mediant500 to ISDN PRI-E1 in Thailand but I got a very distorted voice for all calls with outside(both incoming and outgoing). but all internal calls by ext no. are working normally.
I am a newbie for these boxes. I found nowhere about voice setting in Sangoma.
So, I have tried adjust Voice Volume (-32 to 31 dB)/Input Gain (-32 to 31 dB)/Silence Suppression/Echo Canceller in the Mediant500 already. It does not help, still got same very distorted voice.Now, I'm not sure that Mediant500 to E1 need a cross over Lan cable or not, will find one to test soon.
Please suggest me to solve this issue
Thanks
