Hi,
I'm trying to strip the leading '1' from an 11 digit number in the From
URI. That is, if I have a From header like this:
From: <sip:17065551212@domain>
I wish for it to become:
From: <sip:7065551212@domain>
I tried to do this via a regex_map - in sbc.conf:
regex_maps=normalise_from
In normalise_from.conf:
^1([0-9]{10})=>\1
And in the SBC profile (yes, I want to replace the From domain, too):
From=<sip:$M($fU=>normalise_from)@$Ri>
But this just results in the following From URI user part: \1
I figured perhaps the regex engine is not so thoroughly PCRE-compatible,
so I also tried the following pattern:
^1(.+)=>\1
None of that appears to yield a result.
Is this because the regex maps facility only supports basic replacement
with static target values? Is it not possible to extract a token and
refer to it? If so, how is it done? I was not able to find any
examples in the package or formal docs.
Thanks!
