Hi,

You need to configure SIP trunk and appropriate dial-peer on cme.

but pay attention if you have Lync redundancy create one dial-peer per Lync node. incoming and outgoing.

Hello Salman,

please, do you have a guide for this?

I have config on cme side. But not Lync side(

sip-ua 
 no remote-party-id

voice service voip
 allow-connections sip to sip
 no supplementary-service sip handle-replaces
 sip
  bind control source-interface gi0/0 (this should be your sip interface, creating loopback and binding to SIP is best practice)
  bind media source-interface gi0/0 (this should be your sip interface, creating loopback and binding to SIP is best practice)

voice class codec 20
