[OpenSIPS-Users] Checking for Initial INVITE in branch route

[Nick Cameo]

Hello Ali,

Thank you for your response. The issue is, I have a service provider
that requires the tech prefix at the beginning of the phone number in
TO tag. Not RFC standard I know... So for this particular gateway we
use  uac_replace_to in the branch. The problem is not flagging the
initial INVITE but when the gateway in question fails, we failover to
the next gw, and hence another initial INVITE...

When we do failover we are getting the following error
"ERROR:uac:replace_uri...". And also, following BYEs and ACKs on the
failover still contain the prefix in the TO from the, lets call it,
non conforming GW....

It seems restore_mode auto does not do anything in the failure route,
and I have to manually do it there?

Thanks in Advance,

N.
