For the very first call I place using my mobile phone, to the UMTS dongle that is used as a mod_gsmopen endpoint, I distinctly hear an announcement, but that is extremely choppy, and I am unable to understand what it says. Soon after, I get a SEGV -- repeatable and already have a JIRA filed for same.

What could be the reason for the extremely chopping announcements? Is it the rather low-end Celeron 1.5GHz w/ 512MB RAM.
