Hi folks, Some of my customers are complaining that sometimes when they are going to transfer a call, it drops. I noticed that when this happens, freeswitch reports the following in the console/logfile: aed6d1eb-c1fe-496f-b520-150ae23918a6 2017-04-04 12:58:13.900620 [NOTICE] switch_channel.c:1104 New Channel sofia/internal/angela [aed6d1eb-c1fe-496f-b520-150ae 23918a6] aed6d1eb-c1fe-496f-b520-150ae23918a6 2017-04-04 12:58:13.900620 [CRIT] sofia_glue.c:1031 Error creating HANDLE! aed6d1eb-c1fe-496f-b520-150ae23918a6 url_str=[sip:angela@10.100.161.3:5060 ;transport=udp] aed6d1eb-c1fe-496f-b520-150ae23918a6 call_id=[N/A] aed6d1eb-c1fe-496f-b520-150ae23918a6 to_str=[<sip:angela@10.100.161.3:5060 ;transport=udp>] aed6d1eb-c1fe-496f-b520-150ae23918a6 from_str=["Outbound Call" < sip:keneja%sabia.pbx.isimples.com.br@10.50.0.1>] aed6d1eb-c1fe-496f-b520-150ae23918a6 invite_contact=[< sip:mod_sofia@10.50.0.1:5060>] aed6d1eb-c1fe-496f-b520-150ae23918a6 2017-04-04 12:58:13.900620 [NOTICE] mod_sofia.c:117 Hangup sofia/internal/angela [CS_INIT] [DESTINATION_OUT_OF_ORDER] Do you guys know what can be causing this?
