 Hi Samuelyes you are correct

 

Hi Samuel

yes you are correct the rule 1 is for the inbound, ISP is forwarding 8 digit towards my router so in my MGCP gateway in significant digits i will enter digit 4 for accepting only 4 digit DN ??? please correct me
 

 

Yes this is correct.

ISP is expecting from me 8 digit so for a 4 digit DN to a make a 8 digit and send to ISP I have to add a calling party mask???

 

Yes you can use a mask or use calling party transformation. either will work

Dont forget to ensure that the CSS on your mgcp gateway has access to the partitions of your phones.

For troubleshooting mgcp you need

debug mgcp packets

FYI, posting the rules,

FYI, posting the rules, without the associated commands to find whether they're inbound or outbound, is useless.

I would assume 1 is inbound, so just leave 4 digits for internal routing

2 might be outbound, so add 2485 + 4 digits.

The rules are perfectly clear on what they do, not sure what you need here, if going to MGCP, replicate this via prefix, significant digits, calling/called party masks, transformation rules, etc, whatever you use.

If you don't understand what the rules do, there's plenty of material on translation rules on cisco.com so you can review it and fully understand what they're doing.

Dear Jaime,For Inbound

Dear Jaime,

For Inbound calls

yes you are correct the rule 1 is for the inbound, ISP is forwarding 8 digit towards my router so in my MGCP gateway in significant digits i will enter digit 4 for accepting only 4 digit DN ??? please correct me

For outbound calls,

ISP is expecting from me 8 digit so for a 4 digit DN to a make a 8 digit and send to ISP I have to add a calling party mask???

Please correct??

This is a working link in H.323 as I am going to shift in MGCP so below 2 commands are enough or another command will give more granularity.
