Per the Asterisk versions page [1], the maintenance (bug fix) support for the Asterisk branch you are using has ended. For continued maintenance support please move to a supported branch of Asterisk. After testing with a supported branch, if you find this problem has not been resolved, please open a new issue against the latest version of that Asterisk branch.

Thanks!

Hi Joshua,


Thanks for your reply. Can you please confirm what version we have to use to remove above issue? Also please let me know the supported Dahdi driver for that version.


Thanks,
Altmish

If you follow the link on the previous comment you can see currently supported versions. The current LTS release is 13 though, and I do not know if it will resolve your problem. It is likely it will but I can't guarantee it. The latest DAHDi will work with it, as will older versions. As you are using chan_ss7 though (which is a third party module) I can not comment on whether it is supported.
