Mobile + FS + FXS = 487 ORIGINATOR_CANCEL
I have this recurring issue when using an ATA with FreeSwitch. The specific ATA doesn't seem to matter, as I've tried two Grandstream's and currently a Patton SL4022. When voicemail is set to ring for 30 seconds, many calls — especially those from mobile networks — get dropped with 487 ORIGINATOR_CANCEL. Oddly enough. the issue never occurs when using an IP phone. Reducing the ring time to 20 sec allows calls to go to voicemail, but presumably doesn't actually fix anything. I've tried a variety of early media & ringback settings, but to little effect. I've searched the mail archives, wiki, and flipped through the book, but while I've found lots of things to try, I'm not really any closer to understanding precisely why the caller leg hangs up. sip trace: http://pastebin.freeswitch.org/14398 -gh
Is 30 seconds an unusually long time to ring before voicemail or am I truly the only person having this issue with ATAs? On a side note, I'm researching replacements for these two FXS ports: * Fax Machine -- Listed only for completeness, don't know what I'd use if not an ATA. * Cordless Phones Has anyone tried using WiFi phones as a primary phone? I'm thinking of trying a Locktec WP04 (http://www.yippz.com/wp04-wifi-phone.html). On the cheap end I thought I'd try experimenting with headsets & voice dialling. -gh
