I realize this might not go down well with the mailing list/newsgroup here ;)

but have you considered a web-managed config-builder such as FreePBX?
Instead of building your dialplan from scratch ?

(I have 5 SIP trunks, 5-7 internal numbers, 1 queue (without IVR), 2 time conditions
 and 10-15 SIP devices, all handled fine with stable FreePBX v12 / Asterisk 11.x,
 on a ~2006 32-bit Celeron 2.6GHz with 1GB RAM and 150GB of RAID, queuing/handling/recording 
4 concurrent incoming SIP calls without problems; 
[that's ONLY because I've only got that many queue members, not b/c it couldn't handle more]
[and I don't run IVR because I've seen no need for it either]) 

(DISCLAIMER : I am in no way affiliated with FreePBX team or Sangoma, 
 otherwise than just running one instance of FreePBX)
