I'm trying to setup up my 2851 to register with two registrars (sipgate.co.uk and voiptalk.org).
Looking at "show sip-ua register status" it seems that I have successfully registered, but oddly it is trying to use the authentication of each other on both:
router1#show sip-ua register status
--------------------- Registrar-Index 1 ---------------------
Line peer expires(sec) registered P-Associ-URI
================================ ========== ============ ========== ============
100XXXX -1 465 yes
8449XXXX -1 165 no
--------------------- Registrar-Index 2 ---------------------
Line peer expires(sec) registered P-Associ-URI
================================ ========== ============ ========== ============
100XXXX -1 165 no
8449XXXX -1 2865 yes
So it looks like it's trying to register using 100XXXX and 8449XXXX with both registrars, which is wrong.
I confirmed this using tcpdump.
I've been using this page to help configure the sip trunks: http://www.cisco.com/c/en/us/td/docs/ios/voice/sip/configuration/guide/15_1/sip_15_1_book/sip_cg-multi-registrars.html
I have this as my sip-ua config:
sip-ua
credentials number 100XXXX username 100XXXX password 7 PASSWORD1 realm sipgate.co.uk
credentials number 8449XXXX username 8449XXXX password 7 PASSWORD2 realm voiptalk.org
nat symmetric role active
nat symmetric check-media-src
no remote-party-id
retry invite 2
retry register 10
timers connect 100
registrar 1 dns:sipgate.co.uk expires 3600
registrar 2 dns:voiptalk.org expires 3600
connection-reuse
host-registrar
protocol mode dual-stack preference ipv6
Am I missing something obvious? :/ What could I be doing wrong?
