Cisco 2811 router gateway configuration assistance

Unanswered Question
Aug 9th, 2008

Guys,

We have Cisco 2811 Voice gateway with 2 E1/T1 port. We have 4 E1, 2E1 for DID and 2 E1 for DOD.

Currently we have Cisco CallManager 4.2 and we want to use the 4E1 to call and receive from outside.

I already configured how to connect from callmanager to PBX but directly from E1 with DID/DOD is my first configuration.

I really appreciate if you can guide me how to configure my gateway in this scenario.

Your quick response and to share your experience and advise is highly appreciated.

Thank you and regards.

I have this problem too.

Hi Marwan,

Okay, here is the topology:

IP Phone-->Cisco CallManager-->Cisco 2811 router--via E1-->PSTN

Can I use MGCP here or H.323 protocol.

Thank you.

u can use both up to u

with h323 u have to make full dial plan on the gateway

while with mgcp u just configure the E1 on layer1 and 2 and enable mgcp defin the call agent[ ur callmanager]

and other config will be on ur callmanger

the following link very very useful and helpful

and also intractive just click on the device and chose the subject u want

Hi Marwan,

Thanks man, as I have seen the link that you give, it is very impressive and helpful.

I will try to implement soon and I will get back to you.

You deserve to get a perfect score, not just 5 if there is more higher than that.

Thank you.
