Hi.
I have a HA CUBE setup deployed for SIP trunking connectivity to our provider. Trunk is registered fine,
also inbound calls are working as expected. Problem is outbound call routing as we have CUBE in HA
there is HSRP configured on outside interface.
It seems that the SBC platform on their side just accepting inbound calls from source IP address SIP trunk
has registered with (for example 10.10.10.21). Dial-peer uses SA with source "virtual" IP address defined on outside
HSRP interface.
Question is if it is possible to define also source (virtual) IP address for SIP trunk registration.
!
interface GigabitEthernet0/0
description To_SIP_Trunk_Provider
ip address 10.10.10.21 255.255.255.0
standby 1 ip 10.10.10.20
!
First active UDP connection is for SIP OPTIONS to provider's SBC, another one is SIP trunk registration.
CUBE-A#sh udp detail
Proto Remote Port Local Port
17 <provider_IP_address> 5060 10.10.10.20 51266
17 <provider_IP_address> 5060 10.10.10.21 63589
Thanks.

Hi,
are you using IOS 15.2.3T or above and a CUBE HA HSRP configuration like this link?
Hope this helps

I'm using IOS 15.4.3T, but it's a standard behavior. Detailed discussion here:
