Hi,

I got a range of DID 51771000 - 51772999. My extensions of IPPhones starts from 71000 to 72999. I am using cisco 3745 Router with NM-HDV card where the E1 terminates. Now i want any user from PSTN could dial this DID number and reach the IP Phone extension as that number.

What configuration do I need to do in the Gateway and on the CCm 4.1.3.

My cisco 3745 router configuration is given below.

Your DID range is 51771000 - 51772999 and the IP Phones have extension 71000 - 72999; so in the MGCP PRI Gateway Configuration page under Inbound Calls section specify the Significant Digits parameter a value of 5. Also if the phone extensions are assigned a partition, make sure that the gateway has a Calling Search Space which can reach the phones partition.

The gateway config looks good.

Hi,

Thanks for your so prompt reply.

Are there any other configuration which we need to do in the CCM or doing what you said in the Gateway will be enough to route the calls.

Thanks

Hi,

There's one more question relating to this which I forgot to mention in my last message.

How will my these IP Phones extensions work with the existing Siemens PBX extensions. I need to make that work also. Because there are around 2000 users who are working with Siemens phones.

What configuration I need to do on the Gateway and in the CCM for this.

Thanks.

Does the Siemens phones have the same extension number as the IP Phones? If they are a whole different range than it is easy and you will need to create Route patterns and point it to the gateway that connects to the Siemens PBX.

The siemens has a totally different range.

Hi,

The Siemens nos. start from 51920000 - 51929999. Now what should I do.

Thanks
