> During test with secure connections with Mitel deskphones we examined a problem with notify action via ami. 
> Asterisk generates a message like :
> *chan_sip.c: peer '3001' HAS NOT USED (OR SWITCHED TO) TLS in favor of 'UDP' (but this was allowed in sip.conf)!*
> and the Mitel phones does not react to the message.
> On the other side when i initiate the notify message vi cli command *sip notify* the phones reacts and the message does not appear.
> Now we compared the notify code via ami and cli and saw that there is plenty of duplicated code in the network setup with one small difference:
> creat_addr differs, cli uses "create_addr(p, channame, NULL, 1)" and ami uses "create_addr(p, channame, NULL, 0)" instead.
> After we made a small patch

> against asterisk 13.23 the message vanished and the notify via ami worked.
> Due the lack of documentation of the parameter we are not sure if this is a valid fix for the problem or a cause of new problems.
