CME calls failing

[love2xlr8]

Hello,

My inbound and outbound calls are having some weird issue, been trying to troubleshoot for days now, but can;t seem to resolve this issue.. Have changed the configs over and over looked at the logs countless times but without any positive results.. Therefore I'm posting my show ccsip errors, and show ccsip messages here and hoping to get some help..

Currently running CME 7.1 on 2801 router with 124-22.YB8

If someone can look at it and hopefully can point me to the right direction to resolve it..

file attached..

Thank you

Hey CSCO,

I'm having the exact problem as the aokanlawon described bellow I keep getting "recovery on timer expiry (102)"

Thx

Hi Love,

I have looked at your trace and here is what I think is going on..

In a sip call flow the following usually happens

1. an invite is sent or recieved

2. you get a trying  sent or received

3, you get a ringing sent or received

4. you get a 200 ok sent or received,,,

in your trace the ff happens...

1. an invite is recieved on ccme

Received:

INVITE sip:2013010000@172.22.1.1 SIP/2.0

To: <2013010000>

From: <3475780000>;tag=3543448330-544274

Remote-Party-Id: <3475780000>;privacy=off

SIP/2.0 100 Trying

Date: Sun, 15 Apr 2012 03:34:02 GMT

From: <3475780000>;tag=3543448330-544274

SIP/2.0 180 Ringing

Date: Sun, 15 Apr 2012 03:34:02 GMT

Allow: INVITE, OPTIONS, BYE, CANCEL, ACK, PRACK, UPDATE, REFER, SUBSCRIBE, NOTIF

Y, INFO, REGISTER

From: <3475780000>;tag=3543448330-54427

SIP/2.0 504 Gateway Timeout

Reason: Q.850;cause=102

2. CCME sends a trying (implies that its going to look for the called number)

SIP/2.0 100 Trying
Date: Sun, 15 Apr 2012 03:34:02 GMT
From: <3475780000>;tag=3543448330-544274

3.CCME sends a ringing...indicating that the called phone is ringing

SIP/2.0 180 Ringing
Date: Sun, 15 Apr 2012 03:34:02 GMT
Allow: INVITE, OPTIONS, BYE, CANCEL, ACK, PRACK, UPDATE, REFER, SUBSCRIBE, NOTIF
Y, INFO, REGISTER
From: <3475780000>;tag=3543448330-54427

4. This next step is where the problem is.

CCME should send a 200 ok to the calling  rather it re-sends the ringing 4 times.

5. Then finally it says wha the problem is ..Which it sends to the calling end..

Sent:

SIP/2.0 504 Gateway Timeout
Reason: Q.850;cause=102

Cause 102, means recovery on timer expiry. Basically CCME couldnt find the called number within the time specified in your session expiry timer..

To resolve the problem you may increase your sip session expiry timer, but I doubt this would work. You may need to look at your config to see why ccme cant find the dialled number.

you can send your config here and we can have a look

[Ayodeji Okanlawon]

Your config?

[love2xlr8]

Hi aokanlawon,

Attached is the config, i did modify it to protect my real info, so the public ips and some of the info is not twhat i have on the CME.. Also the SIP is being authenticated by IP not the username and password..

Thanks

[Ayodeji Okanlawon]

on your ephone-dns, I cant find the called number? have you removed this fromyour sent config..

[love2xlr8]

No I did not, but been modifying the configs trying different things i might have removed it..

[love2xlr8]

I looked at my old configs and didn;t have that option before.. Is this added under the ephone-dn x config ?

Thx

[love2xlr8]

I think I'm narrowing it down- I'm not an CME expert so it would take some time till i get to know it better ..

This is what I have noticed so far.

1. I removed the SIP-UA as there is no authentication is required.. I was getting the calls to ring but the called part picked up and the calling party was getting a ring back. Weird!!

2. I added   bind control source and  bind media source  fa0/1(public Interface) and the calls didn't even hit the CME, changed the interface to fa0/1.1 which is configured with the CME IP 172.22.1.1 the calls reach the CME, but out going calls are trying to get out with my private IP..

3. If I remove the bind statement(s) call fails and don;t start rining for 2.06 mins..

If anyone can put his/her 2c would be greatly appreciated, as I'm going bananas for many days now ..
