dear 

im trying to create dial-peer voice pots but its shown an error: could not add peer as per attached pic

The "ERROR: could not add peer" error message is displayed on the IOS voice gateway when an attempt is made to add a dial peer to an existing dial-peer configuration

whats the kind of ram should i ask for ? there is a specific type of ram related to my router 2911 ?

whats the maximum size of ram should i upgrade to ? or what do u recommend ?

thanks

[Balram Vishwakarma]

@correction in the reply : It has only 1 slot

Georgios have added the sheet with part number please follow that to order the RAM.

For the 2911 you have maximum of 2 GB RAM support.

Cisco 2911
Expansion Type—UDIMM with ECC.
UDIMM sizes—512 MB, 1 GB, 2GB.
UDIMM expansion slots—1.
Fixed onboard ECC memory—512 MB.
Maximum memory—2 GB.

Below link have list of supported RAM in ISR G2 please see table 1-8.

should i choose from one of these :

MEM-2900-2GB=	2GB DRAM for Cisco 2901, 2911, 2921 ISR (only as spare)
MEM-2900-1GB=	1 GB DRAM for Cisco 2901, 2911, 2921 ISR (only as spare)
MEM-2900-512MB=	512MB DRAM for Cisco 2901, 2911, 2921 ISR (only as spare)

[Georgios Fotiadis]

That is correct. You should order either MEM-2900-1GB= or MEM-2900-2GB=, as you have only 1 slot for RAM DIMMs.

[amralrazzaz]

thanks alot

so what do u recommend to me buy 1 or 2 gb ?

also this is the excat type  (MEM-2900-1GB= or MEM-2900-2GB) i will ask for in market ?

or what the type of ram  should i ask for ?

[Georgios Fotiadis · Accepted solution]

That would depend on your environment and how "busy" your router is. Also, high RAM utilization is usually seen in boxes with large routing (eg BGP) tables and if they run multiple functionalities (extra zone-based firewalls etc).

Of-course, since the 2911 has only one DRAM slot, if you can take over the extra cost of the 2GB DIMM it would be good to purchase it, since you never know how you will be using the router in the future. But, to serve as a voice gateway in a normal enterprise, the 1GB DIMM should be enough.

thanks alot boss appreciate ur kind help :)

just whats the type of ram should i asked in market ?

is it has a serial number or specific name or type or brand ?

thanks

This will help you with the memory part numbers (Table 8):

Then follow the hardware installation guide:

You should engage a Cisco Partner; they will take care of the ordering.
