[asterisk-users] Weird Polycom SP 650

[Aldo Bergamini]

Hi,

I am seeking help with the installation of a Soundpoint 650 desk phone.

Although I have some experience (and a good one! no single issue so  
far, besides the problem I am trying to solve...) installing a few SP  
320/330 units, I am having several issues with my first SP 650.

  Polycom SP 650 Data:

   	• P/N:		3150-11530-212
  	• SD Sound
  	• FW:		2.1.2.0078
  	• Assembly: 	2345-12600-001 Rev.G
  	
The first thing I have noticed is that I was not able to upgrade the  
unit's firmware with the one currently available in the support area  
for this phone. The TFTP setup I used had worked for the upgrade of  
some additional SP's (SP 320/330); besides the fw files, that I got  
twice, even if I am not sure that this is necessary.

The second strange occurrence is the inability to change the unit's  
display language (to Italian settings).

I was however able to activate the BLF function (through a  
customisation found online for the sip.cfg config file), joined with  
the activation of the 'Presence' setting for some custom created  
entries of the Directory of the phone.

Furthermore, once installed at my customer's site I had to fiddle with  
problems related to DTMF tones. The customer reported that she could  
not link to voicemail, to get messages. And as a matter of fact when I  
checked there was no way to dial the password into Asterisk, until I  
changed the SIP settings for this extension to 'Inband'.

Needless to say that the other SP 330 have no similar issue, with  
'copy cat' settings in the sip.conf file.

What is however a complete disaster is what happens when the user is  
talking on a call, and for any reason, a second calls is presented to  
the unit by the Asterisk 1.6 server.

The user has its headset speaker muted (and therefore thinks that the  
call was lost/ended abruptly), yet the party at the other end of the  
call is still alive and well (aka connected) and has no idea we my  
user starts blabbering about problems to the call.

Does anybody have similar experiences with the 650? There is very  
little I did differently on this unit than on the other SP 330s that  
are running without a problem, on the same Asterisk setup..

Any additional questions are more than welcome!

  Kind regards
  Aldo
