I have a couple of quick questions, just for my general understanding, hopefully someone will be able to explain them in simple english (or spanish), as the relevant searches in google don't really enlighten me at all. Question 1 What causes intermittent Lagging on local phones? If I just sit and stare at "tail /var/log/asterisk/full -f", during the course of a given hour, I se messages such as Question 2: Not really sure how to even phrase the question, so here goes: What is the call flow between contexts? I get this error message on my log file, which is clearly a context issue: However, the exact same config works on Trixbox. Clearly, I have a context issue going on, but I can't understand why if I am running asterisk 1.6 on both, Elastix doesn't work out the context and trixbox does.
