Sourcing SIP-UA registration from HSRP Virtual IP address
One of my offices SIP trunks requires registration. In single CUBE mode this isn't an issue.
I have recently been configuring HSRP for CUBE HA and my registrations are being sourced by the interface IP rather than the HSRP Virtual IP address. In the current config, each router will attempt the registration and the last router to have registered with the ITSP receives SIP calls which breaks inbound calling when the standby router receives the INVITE.
Is there a method of binding SIP-UA registrations to interfaces as it can be done with dial-peers, or another method of forcing the source IP of SIP registrations? I thought maybe I could track the HSRP Virtual IP and only have the route to the ITSP sip server come up when the Virtual IP was active but I don't see a way to do this.
Right now registrations are coming from both active and standby routers, via their interface IP's:
it looked promising but unfortunately "bind control" under global config breaks communication from inside interface (facing from CUCM). On the other hand it fixed the REGISTRATION to external SBC.
Sure I have bind statements defined with all the dial-peers. I'll try to add incoming dial-peer matching URI Via field in OPTIONS.
! voice class uri 1 sip host ipv4:188.8.131.52
! dial-peer voice 200 voip session protocol sipv2 incoming uri via 1 voice-class sip bind control source-interface GigabitEthernet0/0 voice-class sip bind media source-interface GigabitEthernet0/0 dtmf-relay rtp-nte no vad !
yes that's the critical part. With the incoming voip dial-peer configuration everything works as expected. Anyway it still looks like a workaround to me, not a real config. Doesn't make sense if everything else except REGISTER uses the VIP address (same behavior with CSR 1000V on IOS XE in CUBE HA).
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
