Problem with Skype & CUE Integration

cisco_planer_it
Level 1
Level 1

Hi there

I've successfully setup Skype to allow incoming calls to our 2851 (+PVDM2) with CUE. Calls to phones are working in so much as the voice is going both ways and is clear. However, if the call is transfered to the CUE, or if the call is endpoint is the CUE directly, the voice from caller to CUE doesn't seem to be being received. I say that because the CUE doesn't record any message from the caller, in addition, the DTMF is being ignored. The attendant playback on the CUE can be heard.

Here is a stripped copy of the configuration, and any help would be appreciated.

I've resolved it. The problem was an access list only allowing udp/5060 when other ports were being opened dynamically.

Dear Sir.

I have same your problem , can you explain more how you resolve it ?

Thank you.

Marwan

Hi Marwan

Yes, I had to modify the packet filter to allow all UDP traffic from the Skype IP's :

ip access-list extended InternetAccess

remark Remote UDP access to the Skype SIP peers

permit udp host 63.209.144.201 any

permit udp host 204.9.161.165 any

permit udp host 193.120.218.68 any

permit udp host 80.252.85.76 any

permit udp host 78.141.179.70 any

We don't have a skype ddi for each user, only one to the main attendant, so Also, all the ephone-dn's needed to be ammeded, such that

number XXX no-reg primary

kind regards

Simon
