Configuration on MOR

In order to receive incoming connections from DIDx you can ether create IP authenticated Providers for all IP's or you can do the following: It is possible to implement multiple DIDx IP addresses by making these changes:

1. Create a provider in MOR, with a name didx:

2. Afterwards, enter any IP (or leave blank) in Provider Network settings, and write down Provider Device ID value, you will need it later.

3. Now connect to your server over ssh and locate this file /etc/asterisk/extensions_mor_didx.conf and find these lines:

[from-didx]
exten => _X.,1,Set(CDR(ACCOUNTCODE)=0)
exten => _X.,2,Goto(mor,${EXTEN},1)

Now you need to change (ACCOUNTCODE)=0 value (0) to Provider Device ID value as follows:

exten => _X.,1,Set(CDR(ACCOUNTCODE)=221)
exten => _X.,2,Goto(mor,${EXTEN},1)

4. Make sure, file /etc/asterisk/sip.conf has this line included:

#include sip_didx.conf

NOTE: sip_didx.conf file contains list of DIDWW server IPs, so this file must be included if you are using DIDx DIDs. Without this list, all incoming calls from DIDx will not be allowed by MOR.

5. Restart Asterisk
Now your system is updated with all the DIDx IP addresses that are listed in their recommendations.

Now there is no need to create one Provider for each IP

That's all
