I am trying to setup SLA BLF With a polycom 670 and asterisk 1.8
I was able to get SLA working and the BLF on the polycom works as well.
However it appears when placing a call on hold, asterisk sends out a notify and the call is put on hold And the music on hold plays. Howerver the BLF remains solid red and does not flash red.
If I use the phone with line keys they function as normal ring for green, red for active and flash red for hold.
Is there anything I am missing? I do have pressence turned on as well.
welcome to the Polycom Community.
The VoIP FAQ contains the following post:
Nov 4, 2011 Question: How can I setup a Busy Lamp Field / BLF with an Digium Asterisk SIP Server?
Resolution: Please check => here <=
Above explains the steps needed to utilize BLF.
Are you saying that if you just "hold" your line the line key flashes but a BLF monitored line does not behave the same?

Sorry here is the phone software version
|Phone Model||SoundPoint IP 670|
|Part Number||2345-12670-001 Rev:T|
|UC Software Version||220.127.116.1181|
|BootROM Software Version||18.104.22.16853|
Correct, if I setup a line key and register it to an asterisk pbx when I call the entension and place the call on hold the line key will flash red. However when I try to place a SLA call on hold the light remains solid red. But the other end you hear the hold music.
Thanks for the faq I will take a look at it.
I am still not fully aware if I am understanding what you are doing.
SLA is a shared line appearance where a line is shared on mutliple phones.
BLF is a Busy Lamp Field that uses the attendant functionality as shown in the FAQ post.
For SLA we support RFC 3265 (call-info & Line-seize)
Have a play around and if you believe there is anything wrong with our implementation please feel free to work with your Polycom reseller to raise a ticket with Polycom support.
I was able to resolve my issue via mac-directory.xml file with the following.
What I am doing is using asterisk to create a key system that will emulate a line key system such as a nortel or nec pbx
<?xml version="1.0" standalone="yes"?> <directory> <item_list> <item> <ln>Line 1</ln> <fn>SLA</fn> <ct>station1_line1@server</ct> <sd>1</sd> <bw>1</bw> </item> <item> <ln>2</ln> <fn>SLA</fn> <ct>station2_line1@server</ct> <sd>2</sd> <bw>1</bw> </item> </item_list> </directory>
This is very interesting to me. This is one of the key reasons we don't use Polycom phones for SLA clients but would like to if there is a way.
Can you explain in more detail how the calls come in using this method? I assume the <ct> field is application specific. We also use Asterisk.
