Re: Sip trunk to ISP ?

Sarg . · ‎02-26-2010

Guys I need help with connecting to my service provider via sip. I have configured the internal lan with

Sccp and one sip dial-peer to unity module on uc500.

I have been give these credentials to use to connect to the service provider but my performance today was just a joke as I could not do it.. can someone please tell me how I should go about setting up this trunk to the provider and do I have to configure translation patters so internal users can use the single sip number when dialing out of the lan?

Here are the details :

Provider ip add: for instance, 2.2.2.2/24

Incoming phone number 2345678902

Voip password cisco

Username 2345678902

Guys any help would be appreciated. Any links are also fine please

Thanks

Guys I managed to gather some configs.

sip-ua

registrar dns:deleted.com expires 3600
sip-server dns:deleted.com

also

dial-peer voice 1 voip

description ** Inbound Calls
voice-class sip outbound-proxy ipv4:2.2.2.2
dtmf-relay rtp-nte

I understand that outbound proxy ip address is to allow only sip connections to the telephony service provider but I do not understand the voice-class part since I did not see anything about voice class in the configuration, apart from the one shown here. I would have pasted the entire configs here but it was sent to me by a pal and it is for the place where he works.

sccp local FastEthernet0/1.10
sccp ccm 172.16.16. 1 identifier 1
sccp

guys I need to just makes sense of these commands so I can come closer to understanding. Help please guys because I may be ask to go to the customer site and install the equipment. I don’t want to be shamed. L

Glad you resolved, sorry nobody replied but as you have seen these are issues better dealt with hands on.
