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:

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

Hi am new to kamilio , but able to make calls, i need to do something really simple if someone can give me an example of it i will be gratefull.
just before the call gets relayed i need to delete a prefix from the sip uri so it gets transformed to the same uir but less 3 digits.
for example sip:123xxx@domain.com mailto:sip%3A123xxx@domain.com >>> changed to sip:xxxx@dmain.com mailto:sip%3Axxxx@dmain.com
i tryed with transformations but still too new and does give me so many errors that kamailio don't start,
tryed subs_uri but i dont know how to tell it to just take the first tree digits, it is usually done for adding prefixes.
please help.
thank you in advance.
on my scenario i am having an asterisk that i dont control sending me an invite for with a prefix i need kamailio to forward that uri to another server minus the prefix.
thank you.
