[cisco-voip] Call loop?

[Voll, Scott]

I might be wrong but I think it's a order of operations thing.

Hi,

I have one doubt, just for curiosity... Imagine we have an H323
configuration similar to the following one:


num-exp 913333112 112

dial-peer voice 2 voip
 description Internal
 destination-pattern 1..
 voice-class codec 1
 session target ipv4:1.1.1.1
 dtmf-relay h245-alphanumeric
 no vad

dial-peer voice 4 pots
 description Emergency external
 destination-pattern 112
 direct-inward-dial
 port 0/0/0:15
 forward-digits all

In the port 0/0/0, we have an E1 to the PSTN with a DID 913333112, with
matches an internal extension with number 112, but we also have a
dial-peer to reach 112 through the PSTN.

When we have an incoming call, we translate the DID to 112, in this
moment, the call goes to port 0/0/0 or to the CCM? We will create a loop
that makes internal extension 112 impossible to be called from the
outside?

I have tested this and the call goes to the internal number, not to the
PSTN

Longest match is dial-peer 4, it should go to the PSTN, but I assume the
call doesn't match this dial-peer because it can't enter and go out
through the same port? Is that correct?

Regards,

Ruben
