[SIPForum-discussion] Use of DHCP to obtain IP of Proxy Server by UAC?

[ayan]

Hi,

Could anyone provide me with a sample message flow in which :
A UAC dosen't have the IP address of it's proxy server and has to
obtain it by DHCP.

(viz-a-viz: RFC3261, Section 4, Page13, Last line of 2nd Paragraph :
The address of the atlanta.com SIP server could have been configured in Alice's
  softphone, or it could have been discovered by DHCP, for example.)

DHCP is used for obtaining our own IP and configurations right? Can it
be used to obtain IP of other devices?
Is "default gateway" parameter assumed to be the IP of the Proxy
Server of the local domain?

Thanking you in advance.

Regards,
Ayan
