Well, one is Simplex, one is Duplex!! (That, of course, was sarcastic) :-) :-) Jim P.S. Duplex would be where you have 2 radios, one for transmit, one for receive, such as a repeater configuration.

The person who programmed the GM300 left him a bridge in the rear port, with that bridge could be heard through the speaker of the GM300 which was spoken in the portable radio device, but to connect the URI was necessary to remove the bridge and place the URICABLE since then not the speaker of the GM300 is heard. Our project is the following, from an IP phone to make a call to a radio. At this time we can call smoothly and through * 99 talk to the radio and heard perfect, however, speaking on the radio cant be heard on the phone. What could be the problem? Please your help and thank you su much in advance. _______________________________________________ App_rpt-users mailing list App_rpt-users@ohnosec.org http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users To unsubscribe from this list please visit http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users and scroll down to the bottom of the page.
