Hi
Currently, I am using the ISR4000 series as a pstn gateway.
Telco provides a pstn SIP connection to this voice gateway
If I would like to add an additional pstn sip connection through another telco (B) provider with different DDI number range, does the voice gateway support this kind of mulitple pstn sip connection?
Below is a sample of my existing configuration to pstn provider, however the sip-ua seems only support 1 telco only
!
sip-ua
credentials username 12345678 password 7 101010101010101010101010101010101 realm 101.101.101.101
authentication username 12345678 password 7 101010101010101010101010101010101 realm 101.101.101.101
nat symmetric role passive
nat symmetric check-media-src
retry invite 2
retry register 10
retry options 1
timers connect 100
registrar ipv4:101.101.101.101 expires 3600
sip-server ipv4:101.101.101.101:5099

According to https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube/ios-xe/config/ios-xe-book/cube_m_sip-registration-in-cube.html#id_115238
It seems like the voice class tenant may help to resolve my problem, but I need to eatablish a lab to simulate this situation.
Question #1:
does the voice gateway support this kind of mulitple pstn sip connection?
Question #2
If I would like to setup another voice gateway that simulate telco SIP-Server,
How can I do that? any document which is mentioned about it?
Thank you
