I find that Issabel users Asterisk 11.25.0 and there is a Cisco Presence patch available.
However I have no idea as to how to patch the Source RPM. I tried follow the process described in the FreePBX link in my original post based on the patch for 11.25.0 and SRPM downloaded from link above, but I get warnings that Palosanto user and group does not exist and it is using root, which should be okay as I did not create this user / group. And then I get stuck at failed to find dependencies while trying to do rpmbuild. Further looking at the asterisk.spec file created in the process of unpacking via rpm -ivh under SPEC dierctory, I dont have Patch12 or %patch12.p1, so I picked up available slot for Patch3 and used that to specify Cisco presence patch. However, then these last step fail:
rpmbuild -bp ~/rpmbuild/SPECS/asterisk.spec
rpmbuild -ba ~/rpmbuild/SPECS/asterisk.spec
rpm -Uvh ~/rpmbuild/RPMS/x86_64/asterisk11-[a-l].rpm --force
rpm -Uvh ~/rpmbuild/RPMS/x86_64/asterisk11-[n-r].rpm --force
rpm -Uvh ~/rpmbuild/RPMS/x86_64/asterisk11-t.rpm --force
rpm -Uvh ~/rpmbuild/RPMS/x86_64/asterisk11-voicemail-11.rpm --force

If a developer can help with this to add a nice feature / phones work, I am willing to make some donations towards the project. I am learning this as part of Asterisk home lab, and have 3 Cisco phones to play with. I have these phones.

I had some missing dependencies that I have installed.

Now at next step, here is what happens.

Hi, you can start playing with asterisk compiled from scratch, doing this things in a rpm based distro can be painful...

Thanks venturinog. I have the Asterisk CLI based solution working fine with Cisco phones and I have not been able to make Issabel allow me to do the same. I could have used the Chan-SCCP, but my understanding is that things like softlkeys like hold / conference and few other things don't work, so need to use Chan-SIP and I have hard time getting that done in Issabel. I tried uninstalling the Asterisk package and then install the patched astrisk that I create outside, but I cannot then start Asterisk as there must be some integration / links between the GUI and Asterisk that are lost. Cisco sold 100 million of these Cisco phones and many of those are now available at low price and these phones look much nicer than any other phones (and they are affordable for people like us. Since all work has already been done by folks like Gareth, so why will Issabel team not include this patch to allow support of Cisco 7xxx, 6xxx, 9xxx phones? Thanks again.

And Asterisk / Digium has this patch on their website for 8 years.

I have successfully patched Elastix 2.5 for Cisco phones previously. You need to compile/install asterisk from source. A bit tedious process though..

Thanks guys. The patch is available at

https://issues.asterisk.org/jira/browse/ASTERISK-13145

and instructions at

http://usecallmanager.nz/patching-asterisk.html

I have limited experience with linux, but I downloaded asterisk source files from Digium and I was able to patch and make it work, but Issabel is a ISO and I thought I could simply uninstall, which I did and then removed the related files / folders and then downloaded source from

http://repo.elastix.org/elastix/4/updates/x86_64/SRPMS/

However I have all sorts of errors. The list of dependencies was long, but I was able to install them, but Aterisk does not work because of errors.

Which errors? I didn't remove any related folders. I simply renamed folders used by asterisk.

Hello Guys,

Can someone help here please? All I am looking for is to have Cisco SIP phones to show BLFs etc and all work has been done and just need to be recompiled, but I cannot find the Issabel source files that I can patch using the available patch.

I am willing to donate $150 to the project for some help here.

Thanks

Hi dpsguard.
did you find any answer about your problem,
i have same issue for enabling BLf in 7975 in issabel with asterisk 11.25.0

Hello everyone
almost the same problem can someone show me the steps to activate the TFTP server on elastix and issabel pbx so that the ip phones has to support the config files.
I have already upgrade the 8 files for the SIP protocol and now the phone display unprovisioned as a message on the screen of Cisco.
May I help me ?
