Hello,

You have only 32MB of flash , i don't think that you can install the latest version.

You have to go to software download and try to find a version from 12.4 that can be installed on 32 MB flash , i think it will be maximum T7 or T8.

As for the config , if you install the same feature set then you will not need to reconfigure anything.

however there is a big risk in what you are doing becasue you have to first to delete the active version file from the flash so you can upload the new one , the only risk that in case of a failure of the router between the time you upload the new file and the time you delete the file , the router will not get up and you have to go physicaly to the router and install a image from the rommon which can take more than two hours.

Thanks Amer

Dear Amer,

I checked under 12.4T there is no version that can be installed on 32 MB Flash. Under 12.3T no software download avaible.

Can't we update the IOS in this case?

Actually i only want to update the image bcz i am now able to allow-connections sip to sip getting message "

Error %Invalid input detected at '^' marker. at sip" 

some body suggested me to update the image. otherwise i have no issue with this image.

Please let me know if there is any alternate to allow connection sip to sip

Thanks,
