Multi-site (MPLS) call transfer caller ID on PSTN (sip) calls

Joe Gadell

Hi,

We have a customer with two UC500s in a multiple site configuration.  We are not using VPN - it is a MPLS configuration with a Windstream SIP trunk.

When a outside call comes in over the SIP trunk and a user transfers the call locally at that site, the user receiving the transferred call can see the caller ID from the original (outside) caller once the transfer is complete.  However, if the user receiving the outside call transfers it to a user at the other site, the receiving user only sees the internal extension of the senders phone even when the transfer is completed. 

Any thoughts on this?

Thanks,

Joe

Hi Joe,

Can you make sure that it's configured on both UC500's?

voice service voice

  sip

    update-callerid

Also make sure that you don't have "no remote-party-id" configured under sip-ua for both UC500's as well.

If it still doesn't work can you attach the 'show run' from both UC500's and include the 'debug ccsip message' output when you do the transfer operation?

Are you doing a blind or consult transfer?

Can you attach your 'show ver/run' output?

Thanks,

Anthony

Thanks for having a look.  This happens on the consult transfer.

The configs are attached.  Remember this is a multi-site over MPLS.  The St. Louis site is the "main" office.  There is a UC520 at each end.

Thanks!

Looks like you are configured for SIP for intersite dialing. Can you try adding-

voice service voice

  sip

    update-callerid


Thanks,

Anthony

Anthony,

I added this command.  It did not make a difference. 

Any other ideas?

Thanks,

Joe

Good to hear!

Thanks for confirming.
