<div dir="rtl"><div dir="ltr">Hello,</div>
<div dir="ltr"> </div>
<div dir="ltr"> Recently I've noticed that phones on our Audiocodes MP-124 adapter do not get the message waiting indicator. It seems like this behaviour has started a while ago after some upgrade (don't know whether it was Freeswitch or Audiocodes). The current versions are FS 1.0.6 and AudioCodes 5.6</div>
<div dir="ltr"> </div>
<div dir="ltr">From various tests I've done with SIPSACK and tcpdumps I find the following:</div>
<div dir="ltr"> </div>
<ul dir="ltr">
<li>
<div>after a Register command a "correct" notify is sent (i.e., the AudioCodes understands it).</div></li>
<li>
<div>later on "incorrect" notify's are sent which are rejected by the AC with "user not found".</div></li></ul>
<div dir="ltr"> </div>
<div dir="ltr">The "correct" notify is:</div>
<div dir="ltr"> </div>

<div dir="ltr">Taking the second one, changing the domain name and sending it with SIPSACK made it work correctly.</div>

<div dir="ltr">(10.64.0.3 is the adderss of pbx-gr.XXX and 10.64.0.8 is the Audiocodes).</div>
