I found a clue as to why the second leg is not returning a local or remote address:
[2023-07-06 11:40:35] WARNING[253072]: pjsip/dialplan_functions.c:903 channel_read_pjsip: No transport information for channel PJSIP/222-0000007d [2023-07-06 11:40:35] WARNING[935126]: func_channel.c:527 func_channel_read: Unknown or unavailable item requested: 'pjsip,local_addr' [2023-07-06 11:40:35] WARNING[40100]: pjsip/dialplan_functions.c:917 channel_read_pjsip: No transport information for channel PJSIP/222-0000007d [2023-07-06 11:40:35] WARNING[935126]: func_channel.c:527 func_channel_read: Unknown or unavailable item requested: 'pjsip,remote_addr' Well…maybe not a root cause but certainly something of interest. This works with the first leg, but not the second leg of the call. From: asterisk-users [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Joshua C.

They look alike because of callerid and target dialed information. They are still independent call legs. I’m having trouble understanding your explanation (googling just led me to generic callerid and target info). I thought a phone’s local_uri would be how to reach that phone (not the other party), and vice versa for the remote_uri. If the above URI info is correct then I must misunderstand their meaning. Could you provide more explanation on how to interpret them (why they seems reversed to me), or a link? I assumed the remote & local URI where equivalent to the to & from lines (respectively) in the invite… They are the From and To header, but what remote_uri and local_uri refers to changes depending on the direction of the SIP dialog. Received call: From = remote_uri, To = local_uri Sent call: From = local_uri, To = remote_uri The contents of each depend on callerid information, settings, the Contact of the target when doing an outgoing call, what the remote endpoint chose for To URI on a received call. -- Joshua C.
