Hi all,

I have a user who is reporting dropped calls at his site.  We don't have any other users complaining of this.


So far, this is what we know:


1.  The manager bought all new Polycom phones. (POE)


2.  They replaced the network switch with a POE version.


3.  It's not just one or two of the phones that have problems.


4.  It doesn't matter if they use the headset or the cordless set.


5.  The ISP reports a very clean circuit.  (Ethernet from the CLEC.)


6.  We don't see their phones become unavailable very often.


7.  They are the only site that seems to be having trouble.


So, where else can/should I look?

Mike.

I would suggest starting with a packet capture of the SIP messages that will include both call legs (i.e. capture at the Asterisk box).  This should tell you who initiated the hangup - the carrier side, the phone side, or Asterisk.
