Jabber for iPhone - Phone Services not working

[drbabbers]

All,

Has anyone ever seen a scenario like this before:

1. Cisco Jabber for Windows working all OK with Phone Services

2. Cisco Jabber for iPhone will not connect to Phone Services

3. Both clients connect from the same source network

4. Both using the same DNS servers

5. The iPhone client is erroring with DNS lookups on the CUCM TFTP... Also can't browse to it from Safari

6. But this works all OK from Windows on the same network... :/

Any ideas?

Make sure you have SIP TCP turned ON (it's OFF by default)

Go to Configuration > Protocols > SIP.  Set TCP mode to On.

Hi Scott,

Are you referring to Cisco Expressway configuration? This is all corporate access to CUCM with no MRA involvement.

Thanks

[Scott Harris]

Yes, I was referring to Expressway MRA. If it is just Desktop jabber phone services you nee, have you created CSF devices?

[drbabbers]

Hi Scott,

The issue is not with Cisco Jabber for Windows. The issue is only with Cisco Jabber for iPhone as per my original post details...

Thanks

...or in the case of iPhones, a TCT device?

Device prefixes:

Desktop=CSF[username]

iPhone=TCT[username]

Droid=BOT[username]

Tablet=TAB[username]

[drbabbers]

Hi Scott,

Yes a TCT device exists in the CUCM.

The PRT from the iPhone mentions it can't resolve DNS on the CUCM TFTP, but Jabber Desktop with the same DNS server can perform this lookup all OK.

Thanks

So, the IM&P portion of Jabber does work?

Are the IM&P servers using hostname/FQDN? or IP?

[drbabbers]

Jamie,

IMP works all ok, issue is just Phone Services

IMP servers are hostname/FQDN

It is very odd as Jabber desktop works fine on the same network...

Any ideas?

Yes im have same problem, with new IOS Jabber not working on Phone Anymore :-(  and cant see how resolve this (speciality Ihone 7, / Plus, 8 and X..... with 6 or 6s this wonking fine)

Is Jabber connecting all OK to IM?

Is your issue just with Jabber Phone Services?

Thanks

Hi,

Did you manage to get this resolved? I have exactly the same issue!  Jabber phone services lost for Iphone and Android when on local network.

Thanks

Our Windows and Android clients work flawlessly on our test but iphones can only use IM or phone services but not both and directory does not work in either scenario.

Hi,

I have this issue all of a sudden.  Android and Apple devices have lost phone service capability, when on local network (not MRA).

Can anyone provide some assistance?

Thanks
