I've got 1760 router configured in cme and the IOS reliese is:
Version 12.2(7r)XM2, RELEASE SOFTWARE (fc1)
flash:c1700-sv8y7-mz.123-7.T.bin
Now my customer wants to configure sip phone but with this relies I'm not able to do this.
Can you tell me wich IOS reliese I have to load?
Is it enough 12.3 or I must upgrade to 12.4?
Thanks
