How can you see the firware running on an Cisco 857? ADSL2+ sync issue

I have an 857 running on an ADSL2+ connection at a customer site.  At first it was running IOS 12.4(15)T and it would not sync at all.  

I down graded the IOS to 12.4(6)T10 and the unit got sync and all seemed fine.  Now after periods of use the router will lose sync and we have to power cycle it to get it to connected again.  The router doest look like it has crashed as the CD light is still flashing.  However when I look in the logs after reboot there is no indication that int a0 went down.

I have been reading other comments on EE and people are suggesting I need to upgrade the firmware to 4.0.0.018.

My question is how can I see what firmware is currently running on this unit.  I have run sh ver and get the following output:

Cisco IOS Software, C850 Software (C850-ADVSECURITYK9-M), Version 12.4(6)T10, RELEASE SOFTWARE (fc4)

Thanks for the response - i can see the IOS is 12.4(6)T10 is this then specifically linked to the firmware? on the Cisco site http://www.cisco.com/en/US/prod/collateral/routers/ps221/prod_bulletin0900aecd801d5c4c.html
table8 it looks like you can have different firmwares running but I am not sure how to see this on the router.

I have been on the Cisco community forums and one user has upgraded to 4.1.1.018 which he says has fixed the problem - please see link

https://supportforums.cisco.com/docs/DOC-6183;jsessionid=66658BF3471DBD37EF31FCD625119CCD.node0

 and comment made on the 25th November - quoted below

"I am please to let you know that firmware 4.0.018 appears to sort out the issues.

Unfortunately my line only goes to 4M even with ADSL2+, but it is stable.

Next report will be on a greater than 12M line"

Aha

"We have also played with DSL Modem firmware 3.0.33 and more recently 4.0.015 (which incidently works very well on UK ADSL2 Annex A).  None have helped."

as author mentioned: it's a DSL modem and not Cisco product
most cisco IOS images comes with tags similar to 12.4(T6) etc
