[c-nsp] 7200 IOS 12.4 NAT SIP issue

[Dan Benson]

I did not get any feedback on this issue so I was forced to do a 
downgrade to the router 122-25.S2 (Know good IOS for this application).  
After completing this downgrade, my SIP phones are working as I would 
expect. 

Equipment used in this setup:

Cisco 7200 VXR
PA-POS OC3
PA-GE
NSE-1  (Also Having same issue on NPE-300)

Cisco Catalyst 6009
Sup-1a-ge2
WS-X6348-RJ-45 with WS-F6K-VPWR 

SIP VOIP phones effected:

Cisco 7960
Cisco 7960s
Pingtel xpressa phone

If anything else I just want anyone else out there to know that this 
issue does exist and I hope at some point to find a solution.  Thanks 
for the help in advance. //db

I have two 7200's running IOS 12.4 with NAT enabled in two completely 
different locations.  I have been doing some NAT pool reorganizing, 
putting certain inside address into specific outside nat pools.  The 
second I did this, all of my SIP VOIP phones stopped working.  When I 
was overloading to an outside interface I had no problem, now that I am 
overloading to a pool of addresses, my SIP phones give me one-way 
audio.  Could this be a bug due to the new code, or is there something I 
am missing?  Thanks for your help.. //db
