Unanswered Question

Does anyone have any successful experience with iPhone integration with CUCM.

Currently running version 7.

If anyone can provide some step by step doc that would be very much appreciated.



I have this problem too.

It depends on what kind of "integration" you're looking for.

If there's any SIP phone software available on iPhone, you may registered that to CUCM as 3rd-party SIP phone.

You may also run CUMC on iPhone. But that requires a CUMA server.

i understand that i can register it as a 3rd party sip but need a bit more info as i'm running into issues with that.

Steps to add iPhone to CUCM (Callmanager) 7.x.

1.Download and install SIP APP on iphone (There are two APPs available on iTunes APP Store, WeePhone and iSip, I would recommend iSip because it allows the setup of multiple accounts.)

2. Add (basic) third party SIP phone to Callmanager along with DNs.

3. Add a user account to Callmanager, the user account will be used by the iPhone Sip APP to authenticate to CUCM.

4. Configure SIP APP with DN, userid/password and IP address of your Callmanager server.

Restart the SIP APP and you should be able to make and recieve call on your iPhone.

Hope this info helps...

tried this.

we have AD sync happening and this user has multiple devices setup.

i have setup 3rd party basic and filled in the mac of the iphone.

cucm has dns setup and i've used the users AD account and password for authentication but it tells us that user is not found.

any other suggestions?

iSIP application is downloaded.

Config the End user profile

Created the Phone profile with SIP ( third party basics)

Port 5060

User id & DN is as per the configured in End User profile.

restarted the iPhone

But now i am gettingthe error as

Cisco Mobile could not connect to the server.

Network is not reachable (1928)

Then it states:

Timed out trying to establish connection, please check server address and port (1214)

What could be the mising configuration in CUCM ?



Aaron Harrison Fri, 03/12/2010 - 08:22


Have you tried verifying you can reach the CCM you are trying to register to? I.e. browse to the web server on it, or ping the phone from the server?



navingolani Mon, 03/15/2010 - 12:13


Yes, ping is not possible,

iPhone is in subnet 192.168.X.X  provided from service provider & CUCM is 10.X.X.X . so since both r from 2 different network, i suggested customer for it to be in same network for the iPhone to be registered with CUCM. But then customer say he got to know from some one that we require cisco Unified Mobility Advantage for cisco unified mobile comunicator to work as in Client-Server solution.

Cisco Unifed cimmunication manager Advantage (CUCMA) will sit behind teh enterprise firewall, & connectes the mobile user with CUCM & other company resources. These security i sprovided by Cisco ASA which proxies between mobile phones on xternal network & CUCMA server.

so could you please suggest me, will this be the correct way or is there any other way for iPhone to register CUCM?

Just to clarify here - you DO NOT need CUMA to get iPhone to register as a 3rd-party SIP device.

CUMA works in conjunction with CUPS and the Mobile Connect/Advantage features of CUCM to provide an enhanced mobility solution that integrates Presence on mobile clients - particularly Blackberries.  There is also now an application made available from Cisco that provides CUMA support for iPhone but again, this isn't required if you are looking to just register your iPhone to CUCM.  You just need a 3rd-party SIP client, some configuration on the CUCM, and network access to the CUCM (i.e., wireless connectivity within the office, etc).

As for CUMA, it does leverage the ASA as a proxy where the ASA is within the DMZ and the CUMA server is on the internal network and can communicate with CUCM and CUPS.  In the original post, it just mentioned generic integration.  If what you actually want is to use CUMC (the iPhone version), then you definitely need to implement a CUMA solution.

I have already done the configuration for iPhone on CUCM as mentioned in above posts.

So considering this error

Cisco Mobile could not connect to the server.

Network is not reachable (1928)

Then it states:

Timed out trying to establish connection, please check server address and port (1214)

I understand this should be solve by linking  the two networks ? do u think implementing CUMA is any how helpful ?

David Hailey Mon, 03/15/2010 - 13:04

Well, here is the problem - you CANNOT use the CUMC client for iPhone without CUMA.  CUMC REQUIRES a CUMA solution to work, period.  So, if that client and it's features are your requirement - then yes, you absolutely need CUMA.

If you just want to use your iPhone as a SIP device, you can download a 3rd-party (non-Cisco) client from the App store as described in the blog post I referenced earlier.  All the steps are there.  It works.

But beyond all of that, I'm not sure how you're trying to access the CUCM.  Are you trying to do this via the Internet (i.e., no VPN) or even 3G?  That's not going to work without some sort of DMZ access into the corporate voice environment, period.  So, that would probably best be implemented as a CUMA solution.

If you are local to the CUCM - as in, you are onsite and connected to corporate network via wireless - then that's what the blog post is geared towards and what most 3rd-party SIP client usage of iPhone with CUCM is centered on.  If the last scenario is true and you cannot access the voice network from the corporate wireless network, then that would be something to broach as a security consideration and then, based on the decision, add the proper routing to do so.

I am having trouble with my ISIP phone installed on my iphone/ipod-touch making PSTN calls out through a Skype for SIP trunk on CME.

The interesting thing is that I also have another CME that uses a regular FXO PSTN connection and the ISIP phone has no trouble making PSTN calls

in this environment.

Would you know what the problem or solution might be to this?  It appears to be due to the SIP trunk.

Thanks for your help

Does anyone know if Cisco's mobility client allows for Rich Presence?

Can users define custom presence or just choose a select few options: Available/Away/Busy, etc?

Can users view the means of communication available to a user on their client buddylist?

James Hawkins Fri, 04/16/2010 - 09:33

The iPhone CUMC client does not support Presence - I suspect the lack of multitasking support in the iPhone may be the reason for this.

It is also worth noting that CUMC does not include SIP client functionality on any platform.

htluo Fri, 04/16/2010 - 09:37

Hmm... not sure if that's right.

As far as I know,

1) CUMC supports rich presence (with CUPS).  The only limitation is you cannot send IM between CUMC client and CUPC client.

2) CUMC does include  SIP client functionality.  But it's used for signaling (call-control) only.  It does not have media control.


yogan.patel Fri, 04/16/2010 - 09:48

Just noticed it in the CUMC release notes - iPhone 3G,3GS do not support presence.

I am still confused as to whether or not this really supports rich presence. I was reading the release notes for CUMC 3.x earlier - and it said that the client couldn't even display whether a user was in a meeting or on a call - instead it just shows Busy. So does the CUMC client really allow users to put up customized presence/status messages?

htluo Fri, 04/16/2010 - 10:05

Oh... sorry, didn't notice you were discussing iPhone. 

Ya, CUMC on iPhone is kind of "special" and has many limitations.  e.g. it does not support rich presence.


James Hawkins Fri, 04/16/2010 - 10:06

Hi Michael,

My answer was based on the CUMC data sheet at:

In Table 2. Platform Feature Availability presence is not ticked for the iPhone platform.

My comment re. SIP was not clear - I meant that you cannot use the iPhone on a WiFi network as a Cisco handset.

To be honest I have not used CUMC on the iPhone platform and am just quoting from the datasheets. Am happy to be corrected if you know differently.

yogan.patel Fri, 04/16/2010 - 10:09

So back to my other question - WM and Blackberry support true Rich Presence? I would be able to put in status messages, or get means of contact for other users? Or is it just a simple Available, Away, Busy?

David Hailey Fri, 04/16/2010 - 10:18

Re: SIP, you can use iPhone on WIFI as a 3rd-party SIP endpoint. It

requires a SIP client installed on the iPhone. So, it's not native but

can be done in some form. I wrote a blog series with Bill Bell on 3rd-

part clients however i don't have the link offhand. is the corporate site.
