I'm facing some problem with Jabber Voice for iPhone, When I use the Jabber Voice for iPhone dial the outbound call to any Cisco Devices (such as 7925 or CIUS), I can dial out success, when I dial the SIP extension to Microsoft Exchange UM or Asterisk SIP Truck (Outbound to SIP Provider), I got the busy tone only.
May I know is there has any configuration, I missed? I tested with two CUCM version 9.1 and 10.5, I got the same result.
CUCM version: 10.5.1.10000-7 and 220.127.116.1100-12
Jabber Voice version: 9.1.7
MS Exchange 2013 SP1
Does the issue happen only with Jabber iPhone client? What about normal IP Phones/ Jabber for Windows/Android clients?
What happens when the same user logs in from Jabber for Windows?
Also, please configure a shared line between an IP Phone and TCT device for iPhone and verify if the issue happens in both the clients. I'm trying to isolate the issue before focussing on server communication.
I would recommend verifying the SIP traces and see why exactly the call fails.
In additional, May I have more information on the shared line?
For the iPhone Client, I configured it has a primary phone and the device mobility device is enabled.
I am facing similar issue, we can dial to all numbers from the Jabber for Windows except inter cluster trunk.
We have CUCM 10.0 with IM&P and ICT trunk to CUCM 8.5, from Jabber we are unable to dial any extension number on CUCM 8.5 through trunk. From IP Phones we can dial, I strongly believe is the CODEC issue.
Did anyone faced similar issue?
What do you mean by SIP extension? Is it just a DN or a SIP uri like sip:firstname.lastname@example.org? And are you able to call these SIP extensions from your IP Phones like 7925 or CIUS ?
