[Spce-user] Emergency Calls in Austria with 0720

[Matthias Hohl]

Hello Daniel,

 

can you give me some more information about the 0720 rewriting for valid
emergency calls in Austria?

I read your instructions but i am not sure if i understand it fully.

Currently we fix it by override the AC with 1 but i want want to use a
automation for it.

 

Hope you can help me out.

Hello,

 

i am not sure how the inbound rewrite rule for caller would look likes in
this scenario.

I didn't have then the "emergency_" prefix then anymore, so how would spce
knows then, that this is an emergency call? 

Or is the suffix independent of the "emergency_" prefix of the rewrite rule?

 

Can you give me some more details about that?

Hi,
you can use Rewrite rules as well.
For your target subscriber you can populate the "emergency_suffix", and then
use it ${emergency_suffix}=invalidAC_ in the inbound rewrite rule for
caller, to prefix the value for call to emergency number.
Then on Peering side you can intercept the ${emergency_suffix} caller,
remove the prefix, the 43720 and substitute it with 431, this is in the
peer's outbound rewrite rule for caller:

^invalidAC_43720([0-9]+)   ---->  431\1

this should work.

Hello,

 

Calling an emergency number from a 43 720 123456 number will currently fail,
cause "720" is no valid AC prefix in Austria.

So I must rewrite "720" to AC "1" to fix that problem.

 

I have done this currently in the subscriber settings that I rewrite the AC
Code "720" with "1" but I was thinking about if this is the right handling
to fix this problem?

I was thinking about rewrite rules, but afaik there is no batch working with
rewrite rules, so the first rule will match and stop, so I can't first
remove emergency_ and then check if "720" is AC and if yes then "rewrite it
with "1".

 

Any other ideas?

 

thanks
