[SIPForum-discussion] Phone registration with NAT

[K Satyadarshi]

Hi

I am trying to register a phone with SER through NAT applied on egress
interface. This NAT translates the destination port in REGISTER msg. When a
200-OK is received, the port is 5060.
Due to this phone doesn't get registered. I have a cisco on which inside and
outside NAT is applied.

I need some help for NAT config on cisco 2800 router and sip register with
SER through NAT applied.

Thanks in advance.
s-a-t-y-a
