In one of the Freepbx/Asterisk systems we maintain, we are seeing a lot of the following message:
WARNING[2996] chan_sip.c: sip_xmit of 0xaea3fc08 (len 490) to 62.232.91.106:43662 returned -2: Interrupted system call
Any ideas as to what is the cause and resolution?
We are using Freepbx 2.11 with Asterisk 1.8.11
Thanks.
