IP TRUNKS

[LouiseF]

Hello

I have set up an IP trunk between two s8700s and the trunk is in service idle and the sig group is in service but when I try to place a call I get engaged tone. Can anyone help

Have you checked the COR's on the extension and the trunk?

I used to wonder where the sun went every night... then it dawned on me.

Hi
i have checked the COR and Trunk, also i get the following when i do a trace when calling from the station, any ideas?

12:33:48 tone-receiver 01A0904 cid 0x14ac
12:33:48 active station 2111 cid 0x14ac
12:33:51 dial 3010 route:UDP|AAR
12:33:51 denial event 1012: Destination Unavailable D1=0x8aaa D2=0x14ac

Can you ping from Clan to Clan both ways?

 

[LouiseF]

Hi, yes I can ping CLAN to CLAN both both ways.

Might be an obvious question, but is the system licenced for IP trunks - check your cust options and features

 

[LouiseF]

The system is licensed correctly. Any more ideas?

Hi,

If the destination is an IP phone, check the VLAN config for the IP trunk and the IP phone of the destination system.

 

[LouiseF]

The phones are DCP phones

Another silly question, is your Medpro setup correctly? And have you traced dialling the TAC?

 

[98Converter]

What about incoming call-handling treatment? You may need to delete the 3 (AAR) digits on the far-end switch.... List trace tac on the far end switch to see if it's getting there, then you'll have a better idea what is happening. You can also list trace tac on the local switch to get more information.

Thanks,

Did you get a resolution to your issue as I have the same issue.

 

[LouiseF]

Hi, it has not been resolved yet

 

[qz01gs]

can you access the trunk via the tac code.

 

[LouiseF]

When using the TAC Code we get engagaed tone

 

[Phoneguy15]

Try doing a list trace on the trunk group and see what denial you get.
It may show you a different denial that will point to the problem.
Is there only 1 trunk in the group?

 

[LouiseF]

Have done numerous traces and always get the same, this is the only trunk in the group.

Have you set the extensions on the dial plans.
Second you can only dial TAC if you haveset dial access on the trunk form.
Third have you set route patterns for the extensions

 

[LouiseF]

Thanks ideal, have tried all these still no joy
The problem is occuring on an s8700 CM 2.1

We have several switches on site; 2 s8700s and an s8300,
i have managed to get an IP Trunk working between an s8300 with CM 2.1 connecting to the s8700 cm 2.1

butI can't get the 2 s8700s to connect with an ip trunk though.

How about a codec mismatch?
