7912 goes into constant loop

Thanks to Jonathon Schulenberg from previvious post to putting me on correct path.Further help needed please

7912 goes into constant loop of Configuring IP, Configuring VLAN,Configuring CMList

Network Configuration on phone shows allocated IP addresss, default gateway, etc of which is correct

Can ping phone, DHCP and def g/w from router ok. But cant stop this constant looping

Runnng CME 3.3 with IOS 12.4

Phone has necessary sbin file according to cme and IOS matrix

Phone displays in CME with correct extension number, caller id/name, mac address and phone loads

Provided output below via attachment of sh telephony-service all and show ephone for more information

Am I doing something wrong....thanks again in advance..

You do not need any of these tftp-server commands.

However, you should urgently update IOS.

7912 goes into constant loop

Thanks Paolo for your reply.

As there are varied IOS updates available for the 2691 multi service platform router



Or perhaps


Do you have a suggestion?

7912 goes into constant loop

Can I only put a 2691 IOS onto  a 2600 router or are routers "forward" IOS compatable dependant on features using?
