Cisco 2901 with PAP2T

[digodox00]

Hi,

I´m trying to configure a voip direct call between my 2901 router with two FXS ports and a Linksys PAP2T ATA.

My router config is:

dial-peer voice 1 pots

destination-pattern 36000[1-2]

port 0/2/0

!

dial-peer voice 2 pots

destination-pattern 36000[1-2]

port 0/2/1

!

dial-peer voice 361901 voip

destination-pattern 361901

session target ipv4:10.31.11.245

!

dial-peer voice 360003 voip

destination-pattern 360003

session target ipv4:10.10.10.245

I can make a call between the two FXS ports but when calling the ATA (360003 - 10.10.10.245) I get the busy tone.

They both are in the same LAN so I think it shoud be some of the ATA's configuration.

I could´t find much information on this configuration.

Does anyone have tryed doing this?

Thanks!

Hi,

The PAPT2 only support SIP over its ethernet for VOIP.

You are sending H323 on your dial peers.

You need to enable SIP

!

dial-peer voice 361901 voip

destination-pattern 361901

Session protocol sipv2

session target ipv4:10.31.11.245

Hi Campbell,

Thenks for the reply.

I´ve updated the dial peer as you recommended but still no success.

I keep getting the error:

rt-csc-2901-01#csim start 360001

csim: called number = 360001, loop count = 1 ping count = 0

csim: loop = 1, failed = 1

csim: call attempted = 1, setup failed = 1, tone failed = 0

Thanks.

One of the problems were the Session protocol sipv2

the other was the codec configuration.

Now I´m able to make and receive calls both ways but there is a one-way audio problem. Only the phone connected to the router´s FXS receives audio.

Any ideas?

Thanks

Rodrigo,

Trick to make Linksys PAP2T working with CUCME is to make device making and receiving calls without registration. Under Line settings you should set yes to Make Call Without Reg: and Ans Call Without Reg. Proxy address is address of your CUCME, you do not need OB Proxy and need to set dial plan at the bottom.

We used this solution for connecting Fax devices to CUCME some time ago and it seems to be working without problems. Unfortunaltely I can not connect to those devices to help you with exact configuration.

Regards.
