Hi Cassius,

 

Can`t help for SPA-942, but the Wiki had good info on the Polycoms.  Use the 
Wiki and you`ll do good. Two warnings:

1)      It seems to me that the adhoc MeetMe room used by the page application 
slows things down quite a lot.  If you page and have a phone nearby, you`ll 
hear yourself with quite a bit of delay.  It`s very annoying if you`re paging 
and hearing the page at the same time. Apparently 1.8 supports multicast and 
will do this differently, but it’ll be a long while before I trust 1.8  to be 
stable enough for my needs.

2)      If you`re doing this over an Internet link (i.e. hosted PBX), keep in 
mind that because of the MeetMe (I imagine), even if the receiving phones 
aren’t creating audio, the bandwidth is still is used as if everyone was 
talking at the same time in a MeetMe room. No biggie if everything is on the 
LAN, but a bit of a problem if not and you have many phones.

 

And here is a tip: auto-answer is good, but you`ll have to loop through every 
SIP registration on the phone before using Page() to see if they are being used 
before adding them to the Page. If not, the phone will not auto-answer (since 
you`re on a call already) but you`ll have a missed call everytime somebody 
pages you while you`re on the phone.  Users hate that (with reason).  You check 
if each and every phone is being used BEFORE adding them to your page.  In 
other words, if 10 out of 15 phones are idle, Page() only those 10.

 

Besides that, things work as advertised. 

 

Mike

Subject: [asterisk-users] advice re: Page() application

 

Hi all,

I'm planning a new Asterisk installation; the users want to duplicate the 
paging function they have with their current Panasonic hybrid system. They dial 
*3 and announce a held call on line 3, for example, and the announcements comes 
out of all the desktop phone speakers. 

 

I'm planning to implement this using the Page() application in addition to 
parking the call. The O'Reilly book doesn't talk much about Page(), just says 
that it dumps the channels into a dynamically created MeetMe room which is 
quickly torn down.

 

To make this work with typical desktop speakerphones, is there anything I need 
to do in sip.conf? (I was thinking I might need to set autoanswer=yes, for 
example). I can use a second line presence on all the phones to support this if 
necessary; I'm using SPA-942s. I don't want all the phones to ring - just have 
the announcement audible at each phone without the user needing to pick up.

 

I apologize for not being able to try this out myself - I'm out of the country 
with no access to sip phones right now. Any help/lessons learned using Page() 
would be most appreciated!

 

Regards,

Cassius Smith
