[IsenLin]

I have CUCM 10.5，Jabber 10.6，Expressway-C&E 8.5.1，H.323 Gateway Route2911 15.4

I can call a number,but it`s no sound(no ringback),Then suddenly pick up...

Hi,

It could be the following bug which is not fixed yet

https://tools.cisco.com/bugsearch/bug/CSCua72781/?reffering_site=dumpcr

VCS does not forward early media on 183 or 180 with SDP

CSCua72781

Description

Symptoms:
Remote ringing tone will not be heard on endpoint registered to VCS Expressway.

Conditions:
Ringing tones sent as "Early Media" via SDP on a provisional response (183 or 180) will not be forwarded.

Workaround:
None. Note this does not affect a call once it has been answered, only the audio ringing tone.

HTH

Then Change CUCM Sip Profile~

It`s Done!
