 Posted: Sat Oct 04, 2014 9:48 am Post subject: [asterisk-users] Pjsip and regcontext (for DUNDi) |
 |
|
Hi guys,
I'm building a PoC Asterisk 12 cluster based on a number of guides I've found on the net. The basic concept is using ARA in conjunction with DUNDi. I have set up ARA with pjsip according to this excellent guide here:
https://wiki.asterisk.org/wiki/display/AST/Setting+up+PJSIP+Realtime
This is working nicely, so now I am turning my attention to DUNDi, as per this guide here:
http://www.ntegratedsolutions.com/wp-content/uploads/2012/07/Using_DUNDi_with_a_Cluster_of_Asterisk_Servers.pdf
Its seems a really neat solution and I'm keen to implement something similar, however I believe it was written before the pjsip channel driver and I've hit a potential issue I think. The guides for configuring DUNDi seem to suggest using regcontext in sip.conf:
[general]
regcontext=sipregistration
However I can't seem to find an equivalent declaration for pjsip.conf. So my questions are:
1) Is there a way to achieve the same functionality with pjsip?
2) Is DUNDi still being maintained and used? If so, then how should it be configured with modern versions of Asterisk?
3) If DUNDi is not really used in modern set-ups, then what are my alternatives?
I really have searched and read and Googled everything I can but I can't seem to find anything on configuring DUNDi with pjsip. Hoping one of you people can point me in the right direction!
many thanks in advance,
Dan

Hi,
Was this question not appropriate for asterisk-users maybe? Should I post in dev instead?

No, I think the question is appropriate for this list. The lack of
immediate response probably had more to do with asking it on a Friday
than anything else

You don't have to use 'regcontext' in order to have the equivalent
functionality. regcontext is an automatic mechanism to create a NoOp
extension matching each peer's name in a particular context. If you
wanted the same functionality for DUNDi, you could create the same
extensions for each endpoint in pjsip.conf.

Not automatically, no. If you wanted DUNDi to use a context with
extensions named the same as the endpoints for DUNDi lookups, you
would need to create them yourself.

DUNDi hasn't changed much; hence, the configuration of things for
DUNDi is generally the same between recent versions of Asterisk. The
DUNDi specific portions of configuration would also be similar between
chan_sip and chan_pjsip.
As far as 'maintained and used':
* DUNDi (which is provided by the pbx_dundi module) is in extended
support. That means most development activities for it come from the
Asterisk community as a whole. There is not a lot of active
development that occurs in pbx_dundi, although patches for bugs are
occasionally merged for it.
* DUNDi is used by a number of community members, and has some
interesting applications in certain setups. I don't have any hard
numbers on how many people use it, other than it comes up from time to
time in the issue tracker (which is about the extent of my visibility
for usage).

Thanks ever so much for the informative response Matt. And apologies about the bump over a weekend. I was working over the weekend and forget other people have a better work-life balance than me! Your input is greatly appreciated

I see. I suppose the nice thing about regcontext in combination with the realtime architecture is it means you don't have to hard code this stuff. I guess my next step then is to look at creating these NoOp extensions via the database.

Thanks again for this info Matt. Glad to hear that DUNDi is still maintained. We already have OpenSIPS doing SIP signalling on our network and I'm trying to avoid needing to add more complexity to that set-up. I really love the idea of clustered peer-to-peer asterisk instances sharing registration information with one another - this seems a really neat design to me.
If I manage to get this proof of concept running I'll blog about it somewhere so others can learn from my experience. If we actually go ahead and deploy Asterisk using this technique in production then I will make sure we help with the maintenance where we can,
all the best,
Dan. |
