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
