[Spce-user] Inbound Rewrite Rule for Callee - strip characters in dialed numbers

[Matthias Hohl]

Hello Barry,

 

can you explain your workarround more?

Is this a valid method to do this?

How does sipwise themself handle this problem? 

Is this maybe also fixed in the new LTS mr5 release?

 

Thank you.

Hello,

 

we have sometimes the problem, that customers dial a number with letters or characters like „.“ Or „-„ or „/“ in it.

This stops rate-o-mat, so we need to rewrite the dialed number to strip out this characters.

 

Like: [^0-9]  =>  „“

 

You could use something like:

 

        if(is_method("INVITE"))
        {
                $rU = $(rU{re.subst,/^(\+)?[:blank:]?\(?([0-9]*)\)?[ -.]?\(?([0-9]*)\)?[ -.]?\(?([0-9]*)\)?[ -.]?\(?([0-9]*)\)?[ -.]?\(?([0-9]*)\)?$/\1\2\3\4\5\6/});
                xlog("L_NOTICE", "Consume spec chars in RURI - '$rU' - [% logreq_init -%]\n");
        }

 

 

..in your templates/etc/kamailio/proxy/kamailio.cfg.customtt.tt2

 

Hope this helps.
