Hi,
We have the following setup:
Cisco Jabber <---> Cisco VCS <---> telyHD (Our Video Product)
Now, the call works well when the call is intiated from telyHD to Cisco Jabber.
But, the call fails when the Cisco Jabber initiates the call towards telyHD.
The packet capture on VCS shows that there is a syslog message from VCS to Jabber indicating the following when 180 Ringing is received from telyHD:
Message [truncated]: tvcs: Event="Decode Error" Service="SIP" Src-ip="10.1.1.19" Src-port="5060" Dst-ip="10.1.11.11" Dst-port="25331" Detail="(User-Agent) Single header User-Agent appeared twice in message" Protocol="TCP" Level="1" UTCTime
Can you please help in troubleshooting this issue. I don't see multiple "User-Agent" headers in the 180 Ringing sent by telyHD.
I have attached the packet capture on VCS.
