There is a core convenience function that can help with this, as long as
you're manipulating the request URI:

    strip(3);

You referred to "the SIP URI", which, of course, is ambiguous since a
SIP request has many SIP URIs.

Hello,

if you just need to remove first 3 digits, use:

strip(3);

If the number of digits to strip is variables, use strip transformation:

- http://www.kamailio.org/wiki/cookbooks/4.0.x/transformations#sstrip_len

If does not work for you giving errors, paste here what you have in the
config for that part.

Cheers,
Daniel

Kamailio is generating a abort at qm_debug_frag function (BUG: qm_*: prev.
fragm. tail overwritten) but I can't understanding the meaning this
abort...  Someone can tell me the purpose of qm_debug_frag function, it
checks if some improper memory handling happened and abort the program?

Below is backtrace of abort:
