Is there a limit on the amout of dial-peers you can have on the gateway? obviously there will be some limit for pots as it will require timeslots on E1 and T1 cards or FXO/FXS cards.
How to determine the maximum number of dial-peers that can be configured on a router
Resolution
The dial-peer options are available based on how much memory is available.
As an example, assume each dial-peer consumes 6k of memory, and that the router does not accept new dial-peers at the 80 percent threshold of memory allocation. This formula calculates the available dial-peer options:
(Free Memory * 0.8)/6k = maximum theoretical number of configurable dial-peers
This number represents the upper limit.
These points must also be considered:
Check the real amount of free RAM. Consider the real size of the decompressed Cisco IOS® and any additional memory already used.
For each platform, it is necessary to calculate the real quantity of memory consumed by each dial-peer.
Caution: More dial-peers can adversely affect the performance of the router.
Issue the show memory command in order to determine the amount of memory that is used.
