Hi! I have that message: *CLI> WARNING[49159]: File chan_sip.c, Line 435 (retrans_pkt): Maximum retries exceeded on call 5a110b6452cb6aeb7620ee5929c581dc at 127.0.0.1 for seqno 177 (Request) I was thinking..why that call is for 127.0.0.1 is it the loopback of the asterisk machine? Thanks for any help Miklos
