Inbound Carrier SIP Caller ID Suppression

[VLT06]

Hi All,

starting to test a carrier service (SIP) which has an NTU that breaks out into traditional POTS services (Carrier SIP -> FXO -> 4331 Router) and am finding that when in SRST, that incoming caller ID is presenting calling number@loopback5 address (example 12345678@10.110.110.1). Does not occur when WAN is up and not in SRST.

Anyway to remove the "@10.110.110.1" leaving just the number "12345678" for example?

You can use SIP-Profiles to modifiy required header.

SIP to FXO for provider handoff?! Why would you take a modern solution with out of band signaling and clean disconnect supervision and replace it with 100 year old analog connectivity?!

SIP SRST and CUBE are now supported as of IOS XE 16.7(1) through the use of multi-tenent.

"Why would you take a modern solution with out of hand signaling and clean disconnect supervision and replace it with 100 year old analog connectivity?!" - Pretty much the same thing that drives most in this world...$$$$.

In Australia, they are decommissioning traditional POTS PSTN to transition over to NBN. For those who can't afford new interfaces, then unfortunately all we have to work with for now. I do agree though - just wich customers had deeper pockets some times :)
