======= Backtrace: =========

You are too late. Bug reports are no longer accepted on Asterisk 1.8, otherwise I would have told you to submit one.

Hmm I used an LTS version assuming that LTS means Long Term Support.

Very disappointing.

It was long term in October 2010, but if you are choosing a long term supported version now, you should be using version 13. … k+Versions

Sorry Just realized it was list as LTS only for security patches.
I guess we need to migrate versions.
