Hi
We are using AS5400s in our voip network and an other vendors sip proxy. We have a problem about PRACK message. Our proxy sends an absurd PRACK message and calls drop. To solve this i searched for disabling PRACK message in 5400s, but i couldn't find a way yet. Is there a way that 5400s dont generate or respond Prack messages?
Best Regards,

Hi Denis,
the PRACK problem of Cisco IOS SIP stack is widely known.
These commands should fix your issue:
conf t
voice service voip
sip
rel1xx disable

Thank you for your reply. But i can not enter rel1xx disable command ? i tried in 12.3 and 12.4 ioses. What can be the mistake?

This command should be present in every IOS since 12.2(11)T
