[asterisk-users] "timeout on non-critical invite" spamming log

[sean darcy]

On 11.17.1:

The cli and the log are full of these warnings:

  WARNING[12110]: chan_sip.c:4086 retrans_pkt: Timeout on 849421411 on 
non-critical invite transaction.

The number is a random 9-10 digits.

What causes them? How do I stop them ?
