I've been searching all afternoon and been unable to find a sizing document for Cisco 2800 and 2900 series routers with CUBE.
I want to get a SIP trunk from my provider to replace our current PRI.
I need to know how many simultaneous calls each router model can handle.
Is there a document that outlines this information?
This should give you what you need
The 2900/3900 ISR's offer better failover and discount HA licensing so are a better choice for CUBE than 2800/3800.
Please rate if helpful.
