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

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

[asterisk-users] Practical limit on dial prefixes for a route
Why not use DBGet / DBPut? I use it for Caller ID and I have over 50K entries in the DB, and there is no appreciable load hitting the DB in the dialplan. And my one install (admittedly modest) hits the DB a few thousand times a day, with up to 46 concurrent calls. -----Original Message----- From: Eric Germann To: 'Asterisk Users Mailing List - Non-Commercial Discussion' Sent: 1/15/2007 6:34 PM Subject: RE: [asterisk-users] Practical limit on dial prefixes for a route Correction, that's Multitech CALLFinder CDMA, not CellFinder.
