I've got a few stanzas in /etc/asterisk/custom/iax.conf that allow a few of us to connect via smart phones. They look like: [friend1] type=friend context=radio-w5omr-r auth=md5 secret=noneya host=dynamic disallow=all allow=gsm allow=ulaw notransfer=yes [friend2] type=friend ; context=radio-w5omr-r auth=md5 secret=noneya host=dynamic disallow=all allow=gsm allow=ulaw notransfer=yes One more, that looks identical to [friend1] that works for me, and -my- smartphone. [friend2] looks different, because that's the user that using iaxRPT as the client (he's got a windows phone and, as far as I know, there's no app for that phone) The call was rejected from his windows based client, citing first that there was some improper configuration for radio-w5omr-r@radio-w5omr-r. hmmm... So, comment out that line, and it said there some improper configuration for @radio-w5omr-r Where's it sending the '@radio-w5omr-r' line? How do I modify the /custom/iax.conf file to all that client to connect? -Geoff/W5OMR
