[asterisk-users] WARNING: Remote host can't match request NOTIFY to call on Audiocodes MP-124 FXS

[Atis Lezdins]

Hi,

I experience my log flooded with warning messages like this:

[Apr 14 01:30:24] WARNING[19514] chan_sip.c: Remote host can't match
request NOTIFY to call
'5239fdfb15d20e5153a2f7365ce2ea4d at 69.80.215.12'. Giving up

I traced this down to point when we added to sip.conf status notifications:

allowsubscribe=yes
rtcachefriends=yes

So, those notifications allow for queue to display (In Use) etc, and
creates no warnings for other devices except Audiocodes gateway.

I wonder is there any way how to disable this message in Asterisk, or
make Audiocodes act correctly?

Below is the sip debug for this (xx.xx.xx.xx is Audiocodes,
yy.yy.yy.yy is Asterisk).

Regards,
Atis
