In this article we will cover the sample configuration for configuring the SIP Trunk to more than one Service provider on Cisco Unified Border Element (CUBE).
There are two parts in this article: Sample configuration & Requirement from SIP Trunk Service Provider
Sample Configuration
interface loopback1
ip address 10.10.10.1 255.255.255.0
interface loopback2
ip address 20.20.20.2 255.255.255.0
dial-peer voice 1 voip
description “Primary path to sip sp-1”
destination-pattern 91[2-9]……
session protocol sipv2
session target ivp4: 10.10.10.2
voice class sip options-keepalive
voice-class sip bind control source-interface loopback1
voice-class sip bind media source-interface loopback1
dial-peer voice 2 voip
description “secondary path to sip sp-2”
destination-pattern 91[2-9]…..
session protocol sipv2
session target ipv4:20.20.20.2
preference 2
voice-class sip options-keepalive
voice-class sip bind control source-interface loopback2
voice-class sip bind media source-interface loopback2
Note: Dual SPs can be used for outbound calls.
More Tech Note Here: Information you require from SP while Provisioning SIP Trunk
What you should get from the Service Provider for provisioning SIP Trunk
Requirement from SIP Trunk Service provider
1. SIP Trunk IP Address ie Destination IP address for INVITES. For example – 20.1.1.4 or DNS
2. SIP Trunk Port Number ie Destination port number for INVITES. – 5060
3. SIP Trunk Transport layer (TCP/UDP) – UDP
4. Codecs supported – G711, G729
5. Fax protocol support. For example – T.38
6. DTMF signaling mechanism. For example – RFC2833
7. Does the provider require SDP information in initial INVITE (Early offer required) – Yes
8. SBC’s External IP address that is required for service provider to accept/authenticate calls ie source ip address for INVITE – 20.1.1.1
9. Does SIP require SIP Trunk registration for each DID? If yes what is the username and password.
10. Does SIP require Digest Authentication? If yes what is the username and password.
