[cisco-voip] SIP-Trunk with To-Header

[Jefflin Choi]

It seems like the SBC has the capability to re-edit therequest-URI so
my problem is solved. Anyway, i still want to know if this is possible
in case i encounter similar scenario on future implementation where
sip provider still uses TO - field.

Thanks in advance.
