[asterisk-users] Practical limit on dial prefixes for a route

[Eric Germann]

Correction, that's Multitech CALLFinder CDMA, not CellFinder.  Sorry for the
misquote.

Subject: [asterisk-users] Practical limit on dial prefixes for a route

Colleagues,

We're in the process of standardizing on Sprint PCS and Cingular phones on a
national basis (~ 50 properties, 1000's of lines).  I manage an Asterisk
install at one location.

I've been looking at the Multitech CellFinder CDMA for Sprint as a dial
backup solution. Basically, it's a CDMA to POTS gateway, tied to a PCS
account.  We would see it as a trunk line and I would like to do LCR and
route out the CellFinder line(s)^ all PCS calls, since we have free PCS to
PCS.

Here's the kicker.  Since we're on a natioinal basis, it would make sense to
have a large LCR listing of prefixes reachable from the gateway, which would
most likely number in the thousands of prefixes.

Has anyone encountered an upper practical limit that * has for prefixes
reachable via a route.  I assume that search time is somewhat of a factor.
The * box doing the routing is a dual core machine with 4GB of RAM, so it
has lots of horsepower.

Wondering what limits users have pushed it to on a large scale.  Could it
handle something like that or would it implode from a huge routing table
(assuming our tech contacts at PCS could supply us with a national listing
of NPA-NXX's on the PCS network).

Thanks in advance for any info.

^ depending on call volume, we may install multiple cell lines ...
