Indeed, but - to play Devil's Advocate - you have to keep in mind that a
lot of LECs and ITSPs:
- Are primarily sales companies, with an engineering appendage as an
afterthought. This means there's no engineering culture, and
consequently, it's not a place where a lot of engineers want to work, so
they have trouble retaining quality talent and end up bleeding OPEX.
- And/or: rely on vendors' consulting to build and maintain their networks.
- Need to replicate and scale business processes to large customer
volumes and workforces consisting, in the main, of relatively average
Depending on the precise mixture of these variables, they may or may not
be able to utilise open source. I've seen a lot of companies,
particularly large, where open source voice platforms, usually having
come in through the acquisition of a small company, just couldn't
assimilate into the "corporate DNA". These acquisitions were usually
abandoned because the vast armies of cookie-cutter Broadsoft and Oracle
people just didn't know what to do with all this Asterisk or Kamailio stuff.
Furthermore, there's always going to be a CAPEX vs. OPEX trade-off; it's
a well-understood fact that open source isn't free. Savings in
licencingand support cost are to some extent transferred into
cultivation of sufficient operational expertise to run the technology,
or to contractors to do the same.
So, like most things, it's really a question of company culture and
talent mixture. As a general rule, you need some sort of nontrivial
internal engineering apparatus to properly own open-source technology. A
lot of ex-ILEC and Bell System people have a know-nothingism that
consists more in throwing money at the problem, seldom altogether
