CIsco CUBE Router Outbound Call Issue

[Ian Beck]

HI,

I have a Cube Router configured

CUCM <-> h323 <-> Router <-> SIP <-> Telco <-> PSTN

Where when initiating an outbound call all I get is a busy tone.

However if I initiate an inbound call, which works fine.

I can then make outbound calls which work fine.

If there are no calls made for a period of time, I go back to the orginial problem.

Has any one seen a simialr probelm or have an idea wher the issue may lay !!

Many thanks

Recreate the problem

- run Debugs on CUBE (debug ccsip messages, debug voip ccapi inout)

- mention calling and called party numbers

- IP address of Phone; CUCM and running conf of CUBE if possible)

Along with the ccsip and ccapi inout debugs, please collect the below debugs for H.323 call leg.

debug h225 q931

debug h225 asn1

debug h245 asn1

Also make sure the inbound and outbound dial-peers are correctly configured.if the configuration looks fine, then with the error code captured from the debugs would help us what is wrong and where.

Hi,

A couple of debugs fro out going calls which fail :

Hi Ian,

It looks like the Telco is not responding to the SIP Invite we sent and hence the call is getting disconnected with

Cause Value=102 - CC_CAUSE_RECOVERY_ON_ TIMER_EXPIRY - Invite expires timer reached maximum number of retries allowed.

There are 3 Invite messages sent to telco but no response from them. Please have a word with them.

Hi,

The intresting point is though, it would appear the Router does not send the invite, itself.

As I have watched traffic out my FW and seen nothing, when calls are made

Until I have done the inbound call, when traffic is then sent both ways !

This is the point I have got to !

Regards.

Why is traffic Blocked in direction towards TELCO on the SIP call leg. If you can fix that Calls will work.

Router is processing the call properly.

>> This is the invite sent out from CUBE to Telco. better to crosscheck the FW and make sure the SIP Invite is reaching the Telco.
