Issue in Nailed-Up Agent call routing

[GenesysEng]

Hello,

Am facing problem in nailed-up agent call routing. As per Sip deployment guide 8.1, i have configured Nailed-up Dn with following parameter.

contact = sip:xxxxxxxxxxxxx@MediaGatewayIp:5060
dual-dialog-enabled = false
line-type = 1
refer-enabled = false
reject-call-notready = true

Below is detailed issue scenario:
1) Outbound call landed on Agent1 who is part of Site1
2) Agent1 wants to consult with other agent. So he dials routepoint.
3) From Routepoint, the call landed on Agent2 who is part of external site.
4) Agent2 is nailed-up agent & my extension number is mapped to Agent2
5) The problem is, call landed on Agent2 desktop, but the call not landed on my extension.
6) When i try to answer the call in IWS, i got "Unsupported operation(media error 51)" error message.

FYI, we are using CISCO gateway. TServer version 8.1.000.79

I have checked SipServer deployment document. But i couldn't find more information.
Even in solution search also, no information's are available. I saw a relevant post in this forum. But unfortunately the solution was not there. As first level troubleshooting, i have removed connection on both tservers & added again. And even i rebooted both tservers. But no luck.

Anyone please help..!

Try to add option/parameter
[code]
sip-cti-control= talk,hold
[/code]
to the annex of the extensions

[GenesysEng]

Sure, i will try it.

But as per sip deployment document( page number 251), For nailed up agent, the option "sip-cti-control" is not require.

Please advise.

[Kubig]

I know that doc says it, but try to configure it. I think it helps you.

[GenesysEng]

I tried it. But still the call not landed on my extension. In IWS, if i click "Answer" button, i got the  below error message after 30sec.

"Call has disconnected - Media Error (237)"

[b]Error msg in SipServer log:[/b]

12:49:41.047 Trc 36002 Request rejected: error code 237(call disconnected)

[Kubig]

Is still the error in SIP log same as in first occurrence or some change in this? Post whole log, please.

[GenesysEng]

Hi,

The problem is still there(Still the call not landed on my phone number. Its landed on IWS window only.)

As suggested, i added "sip-cti-control" option. When i click the "Answer" button in IWS, the call was not answered. After few sec, I got "Call has disconnected - Media Error (237" error message in IWS

cti-control will work only after call is already established (nailed-up) - for the first time call needs to answered manually. Problem needs to be in SIP signalling to the gateway

BTW - can You use service for sharing files that doesn't require other people to log in/register/pay to download Your files

[Kubig]

I am little bit confused from the logs, but what I see is that the SIP error message - [code]405 Method Not Allowed[/code] is occurring still before answer call request, next thing is that ISCC communication looks wrong:
[code]
@12:49:28.5381 [ISCC] Error: Missing or invalid attribute: ServerName
@12:49:28.5381 [ISCC] Server is rejected: message ISCCEventAuthorizeResponse
ISCCAttributeTrackingID 29415728 [01c0d930]
ISCCAttributeReferenceID 15437556 [00eb8ef4]
ISCCAttributeResponseCode Not_Configured
[/code]
next SIP error is [code]481 Subscription does not exist[/code]. So, as Bublepaw mentioned and I agree with him, it looks like SIP connection is not established yet - like this [code]Timer expired on connection[/code].
