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

[Matthias Hohl]

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]  =>  ""

 

But 

We tought about to set this rule in the inbound rewrite rule for callee
setting.

As we can see in your handbook, the rewrite rule process stopps after the
first match, so this would be no solution, so we need to do this rewriting
before the inbound rewrite rule for callee takes affect.

 

Is there a way to do this strip process somewhere in the kamailio settings
directly?

 

Thank you.
