Hi,
What did i mean by SIP gateway is a SIP-PSTN gateway which does the routing
of PSTN calls from IP network.
Let me reframe the query like this..
In a SIP-PSTN call scenario,
1) UA <[EMAIL PROTECTED]> wishes to INVITE
[EMAIL PROTECTED]
2) Sends INVITE with Req.URI as [EMAIL PROTECTED] proxy.
3) Proxy(domain2) contacts LS and forwards the INVITE with req.URI
<[EMAIL PROTECTED]>.
In this scenario,how LS was updated with gateway's address for this PSTN
line? Does it mean that SIP gateway used REGISTER request or TRIP for
registration?
Thanks,
Anand
