Hi,
I have connected the E1 from Service Provider to my Astersk IPPBX then via another E1 cross over cable to Panasonic TDA100D PRI card.
I am successfully able to handle all incoming calls and direct them via IVR / manual transfers to the Panasonic analog extensions flawlessly.
My problem is, when the Panasonic analog extension wants to make an outbound call, it does; but the conversation is half duplex. E.g. when I call my cellphone number from my Panasonic analog extension using the E1 trunk via Asterisk, I am able to connect to my cellphone but, I can only hear the conversation on my cellphone; it is blank on the Panasonic analog extension.
When I checked the recording of this call, Asterisk is able to give me the DTMF inputs and I can also hear the conversation from the Panasonic analog extension to my cellphone and from my cellphone to the Panasonic analog extension. The conversation is one way but in the recorded file, I am able to hear both sides.
I have checked, re-checked, and kept checking the Panasonic settings and the Elastix configurations and am a little short of pulling my hair apart now...
