Hi,


Have one customer who has a SIP provider in Norway. In sweden they are not able to get a SIP provider yet, so they want to use the CME in norway for outgoing calls at the swedish location. What is the best way to set this up??? They use site-to-site VPN between the CME's using ASA box's.

How can I configure the dial-peer (0T) to use the CME in Norway for outgoing calls??


Thanks,

Eivind

Same thing. On the Sweden side, create a VoIP peer that has a destination pattern equal to what you have on the Norway side. Session target should be the WAN IP of the Norway UC500. This UC500 will then relay the call to the ITSP. Additional translation rules might be needed, in order for your SIP trunk provider to accept the call as if it were coming from the local device.


Thanks,


Marcos

Marcos,


I´ve done this setup before, but as I´ve understood this, this is only for calling between sites. I want the swedish (odd pod) to dial the PSTN using the SIP account from ITSP on the norwegian uc (even pod). The VPN is for sharing the data vlan as well, so therefore the customer wants to use the VPN for voice also.
