[Freeswitch-users] Registration issue with Polycom

[Craig Guy]

Hi Brian,

 

I suspect that FS may not like the contact header in the sip REGISTER
request.  The source port of the REGISTER is 5076, the contact header also
specifies port 5076, and there is no mention of port 5060 anywhere in the
REGISTER message itself.  Note that the Polycom has appended 'methods=' to
the contact header.  I'm not familiar enough with the RFC to know if this is
valid for the contact header, but I won't rule out that this additional
stuff on the contact header is causing FS to discard it and use port 5060
instead of the requested 5076.

 

Neither of my Snom or Billion contact headers are formatted this way.  I
might see if I can find a Polycom firmware update and see if that changes
the header.  

 

Craig

I'm going to gues that nat is involved... and the polycom doesn't rfc3581 so
you'll need to turn on NDLB-force-rport on the sip profile so we respond on
the port we received the initial inbound registration from.  Notice it comes
in from 5076.. yet we 401 it to 5060....   This is the reason the polycom is
number two on my list.

Hi,

 

I've got an issue trying to register a Polycom IP320 against FS 1.0.1, as
below the Polycom is coming from and registering with a contact port 5076,
however FS is sending the 401 to port 5060.  Any ideas?  I have a Snom
registering successfully as 1000 from behind a different NAT.  Any ideas?
