Hi!<br>
<br>
I have a setup with Asterisk in front of a PBX connected with ISDN to<br>
the PSTN and to the PBX. This Asterisk (a old 1.2 instance) is doing<br>
ENUM for outgoing calls and allows incoming calls per SIP.<br>
<br>
Recently the IP connectivity for this location was down the whole<br>
telephony was down too - not even incoming calls did work. This is<br>
really strange as incoming calls from PSTN are routed directly to the<br>
PBX without any IP needed, ISDN to ISDN.<br>
<br>
Once the IP connectivity was reestablished everything worked fine again.<br>
<br>
So I wonder what could be the reason that Asterisk blocked all the<br>
telephony.<br>
<br>
thanks<br>
