Hi,
Sorry to resubmit on much the same topic as before (Portal for forking
call to preferred end device-sequential ringing) but I was wondering if
anyone had any further ideas on how to associate a particular contact
address with a location. i.e. a user can choose that their preferred
location is their desktop phone and I need to devise some way to know
that a particular contact address is associated with the desktop phone.
I was thinking the user must either enter the device ip addresses
manually so I can search the contact based on IP address (This sucks in
terms of NAT, scalability and losing mobility over networks) OR I could
perhaps stipulate that a user cannot have two of the same device e.g.
cant have two BT100 hardphones and I could search the location table
based on model. I think either of these options aren't great....Which is
why I was wondering if anyone had any better ideas?
Many Thanks,
Aisling.
p.s. I currently retrieve the users contact address and q value via a
web interface using the serctl fifo interface.

Hi Aisling,
There are many ways to implement serial forking - like using CPL, LCR or
AVPOPS.
But the main idea (if I getting right from your initial email) is to
allow the user to order his contacts for the same account (like account
userx that have contact_pda_x, contact_PC_x, contact_office_x, etc). So
you have all this contacts in user location, you have several mechanism
for serial forking, but you are missing the link - to get the contacts
from user location and to feed any of the serial forking mechanism. This
is the big problem.
even if you use CPL, you need to place in each location node the
contacts (and not the AOR) of the user, contacts which are dynamically
stored only in user location.
what you are describing below can be possible only if you a user (as
person) has different sip accounts (SIP users) for each of his devices.
Other way I don't see how you can place in the CPL script the "phone1"
and "phone2" addresses.
and just to answer you to the CPL- related questions (from
implementation point of view):
- each user can have only one script - if you load a new script, the
previous one will be lost (overwritten). If you can different services
via CPL (like screening and no-answer), you need to mix them in the same
script during provisioning.
- if you want to delete a CPL script via FIFO, use the REMOVE_CPL
command:
serctl fifo REMOVE_CPL user@domain

bogdan

Hello,
Many thanks for the ideas so far.
I looked at CPL Greger and I think that provides a very simple solution
to this - a simple Call forward on no answer script.
I have an included an example that I came across below. If a user wants
to modify the order of the devices a call should be sent to, then I
simply have to retrieve the information from the user via the web
interface and provision a new cpl script. I think this solves the
problem - Does anyone foresee any problems with this or think it has
disadvantages?
I do have two minor questions if I am to go ahead with this direction
though:
1) If a particular user already has a cpl script e.g. a call screening
script uploaded to the database and they then upload this forward on no
answer script, will it overwrite the original script? i.e. can there
only be one cpl script per user?
2)How can a cpl script be "undone" or deleted? Must it be overwritten
or
is there a way of simply removing it(without using
mysql commands)?
Example CPL: Call Forward on No Answer
<?xml version="1.0">
<cpl>
<subaction id="phone2">
<location url="sip:2000@phone2">
<proxy />
</location>
</subaction>
<incoming>
<location url="sip:2000@phone1">
<proxy timeout="8">
<noanswer>
<sub ref="phone2"/>
</noanswer>
</proxy>
</location>
</incoming>
</cpl>
Many Thanks,
Aisling.

Ok, just to recap - cos Im getting a little bit
confused ;)
I have two choices(?)
1. Somehow invoke sipsak to configure permanent addresses with a
particular q value.
2. Develop a FIFO method to change q value.
Yes. Except that I don't know if anybody verified that q value cannot
be
changed with today's FIFO. I just asked the question...
Am I correct in thinking directly modifying the
usrloc table in the
database is out of the question because the changes cant be updated
except by SER itself in which case a reboot would required - Correct?
Correct. "SER itself" is here either serctl, sipsak or FIFO.
Also lcr module (load_contacts() etc) isnt
suitable for per user
configurable sequential forking?
I don't know about that. There is definitely a q-value based
functionality
there.
Have others tried to implement similar
functionality or is it usually
a generic site wide sequential forking policy?
I think using CPL could be an option. Have you looked at CPL and the
cpl
module?
