I'm connecting an handset to an E&M 4 wire interface via LMR VOIP to radios with E1 interface.
The radios are either TX or RX. As such I need to separate the E&M RX and TX trunks which will eventually end up to different E1 timeslots.
The "connection trunk xxx" command seems to start a full duplex trunk. Is there some way to separate the Rx and Tx trunks for E&M and E1 CAS interfaces to different destinations? E.g. equivalent of a command option like
voice-port 0/1/0
connection trunk 1111 receive
connection trunk 2222 transmit

If i understood Correctly the LMR voip is the base station for your radios ?
I have done few Motorola radio integrations where they can call CUCM extensions which they connect through the SIP trunk created between CUCM and Tetra PBX, such integrations isnt possible with your system ? Why do you choose E&M ?

Hi Nithin,
There is a specific handset used with a Push To Talk button connected to the E&M port on one side.
Like this:
|E1------> TX RADIO
|HANDSET WITH PTT| <--> |E&M to VOIP| <-----> |VOIP to E1 CAS|
|E1------< RX RADIO
I'm open to use any VOIP protocol as long as it can do this:
