asterisk users - Jan 2005 - oh323 context for peers

I am experimenting with oh323 channels and h.323 gateways and a Cisco
CallManager. I am not using a gatekeeper at this time. Is it possible to
place calls coming into Asterisk from specific peers into specific
contexts?

In iax.conf eaxh peer has a context in which I can specify the context an
inbound call will be placed in. I don't see anything like this in the
oh323.conf file or the oh323 documentation.

Thanks,
Adi

Yes. You can associate called numbers/prefixes with contexts in the
[register] section of oh323.conf. If you want to send all calls
to number AAA coming from H.323 endpoints into Asterisk, then you
add the following block in the [register] section:

context=test
alias=AAA

Per H.323 endpoint configuration options in oh323.conf is
something under development.

Hi,

there is a workaround what is doing this job in most cases:

Use as general context in oh323.conf something like e.g.

context=oh323

Then in extensions.conf or better in a file like oh323peers.conf
included in extensions.conf switch to "contexts per peer" via gotoifs:

e.g.
[oh323]
;;;;;; below here are all peers with fixed ip addresses
exten => _.,1,gotoif,$[${OH323_RADDR} = \
     1.2.3.4]?peer01|BYEXTENSION|1
; below only traffic from our gatekeeper
exten => _.,2,gotoif,$[${OH323_RADDR} != \
     5.6.7.8]?4
;;;;;; below here are all peers which prefer authenticating
;      by H.323 username and passoword via our gatekeeper
exten => _.,3,gotoif,$[${CALLERIDNAME} = \
     peer02]?peer02|BYEXTENSION|1
;;;;;;; everyone who arrived here is not authorized
exten => _.,4,noOp(no such peer)
exten => _.,5,hangup


Wheras 1.2.3.4 is the fixed remote ip address from
your peer1.

5.6.7.8 is the ip address from your gatekeeper (e.g. gnugk)
which verifies the H.323 usernames via passwords.

You can expand this example with further fixed ip address
and further users, which authenticate via your gatekeeper.


Roger.

This will work ok for my purposes, where I work with CallManager and
gateways.
