SIP Trunk - use host name instead of IP address

Hello folks

CUCM SW 7.1.5.33900-10. Direct SIP trunk without CUBE.

Can Call Manager use host name in the  @ field instead of IP-address on outgoing calls?

I mean instead of:

INVITE sip:400@192.168.0.16:5060 SIP/2.0

to send its hostname

INVITE sip:400@cucm71.smart.net:5060 SIP/2.0?

DNS server in CUCM is configured and works fine.

In System/Server FQDN of CUCM is configured too.

Thanks in advance,

Absolutely as long DNS can resolve it, in fact you can use SRVs.

HTH,

SIP Trunk - use host name instead of IP address

Sorry folks for misleading. Just pasted wrong fields.

Mea culpa...

Of course DNS is working.

I meant whether it is possible to use host name in a "From:" and "Contact:" fields on SIP calls rom CUCM. Now CUCM sends its IP address, like this

From: "Beldy" <208>;tag=72de3cc6-fbcc-4b3a-a10d-b3a049360db6-28842500

Is it possible to have  

From: "Beldy" <>208@cucm71.smart.net>;?

SIP Trunk - use host name instead of IP address

Yes,

You can use sip profiles...

voice class sip-profiles 1

request INVITE sip-header From modify "<>" "<>1@cucm71.smart.net>"

request INVITE sip-header Contact modify "<>" "<>1@cucm71.smart.net>"

Then you need to apply it to the appropriate dial-peer

dial-peer voice 1 voip

voice-class sip profiles 1

Thanks for the info.

Unfortunately it is direct connection from CUCM to another PABX without any router in between.
