Dear all,

I have a trunk between two cucm 4.3,

and i'm facing a problem when transferring an external call that arrives to site 1, to a person in site 2 through the trunk.

the scenario is as follows:

A call arrives to site 1, i answer it and i click on transfer to transfer the call to a person in site 2, i could talk with that person to tell him that someone needs to talk to him, but when i click transfer again to fully transfer the call, the call will be disconnected, the person in site 2 hears a disconect signal, and the person calling from pstn doesn't hear anything.

can anybody help about that urgently pls

Sorry,

You are using Call Manager 4.3 :P


Configure the trunk as OnNet:


Step 1 From Cisco CallManager Administration, choose Device > Trunk.


The Find and List Trunk window displays.


Step 2 To list the configured trunks, click Find.


The trunks that are configured in Cisco CallManager display.


Step 3 Choose the trunk that you want to configure as OffNet or OnNet.

Hi,


What king of config do you have in "telephony-service" -> transfer-pattern

And "voice service voip" -> allow-connections


Regards,

Nuno

hi Nuno,


first thank you for your reply,

this is not a cme, so i don't have telephony-service commands,

in "voice service voip" i have allowed h323 to h323 connections.

is it a codec/trancoding problem..??

thanks again.

the trunk is already configured as OnNet..

i was thinking about something,

since the call between me and the caller from pstn is using g711, and the one between me and the person in site 2 is using g729 coz it is passing through the trunk, so when i click tranfer for the second time both party couldn't talk together because of a codec isuue??

am i thinking right?? and what would be the solution in this case??


thnaks a lot Mr. Nunoscosta

You are right about codec issue.


Are you using Media Termination Point for transcoding?

I think you need that!

Thanks a lot Mr. Nunoscosta,


i solved the problem finally, but i'm still surprised coz they said it was working before but they didn't have transcoding configured on gateway and on cucm..


anyway, i learned how to do that and i successfully configure it..


thanks again..
