SIP Trunk invite showing "extn name" instead of "extn no' in FROM Header

[Tinos]

Good day all.
Which setting in SIP Peer Profile changes the invite FROM header from displaying extn name to displaying extn number?
Thank you.

Try enabling "Name supression on outgoing Trunk Call" in the COS. Might have to try applying it to both the calling set and SIP trunk's COS.

Thanks for that Lundah however when this setting is set to YES the "extn name" is replaced by "Private" and not the extn number. Please advise further.

I had to set suppression to NO then assign CPN substitution and all is fine now. Thank you

Was there not a default caller id value on the peer? I always add the default caller id to the network zone the phones are in.
