Two SIP TRunks to same ISP wth same realm

[Vianyfel Cordaro]

Hello I have a CUCM connected via SIP Trunk to a CUBE, I need to set two SIP Trunks from the CUBE to the SAME provider.

  But I have only been able to correctly register and establish one because the ISP uses the same realm, and placing the authentication for the second SIP only updates the first one.

 credentials username XXXXXX password 7 XXXXXXXXX realm isp.com

 credentials username YYYYYYY password 7 YYYYYYYY realm isp.com

 authentication username XXXXXX password 7 XXXXXX realm isp.com

 authentication username YYYYYY password 7 YYYYYY realm isp.com (This command only update the first authentication beacuse is the same realm)

 registrar 1 dns:isp.com expires 3600
 registrar 2 dns:isp.comexpires 3600
 sip-server dns:isp.com

How can I do to register the two sip to the same provider with the same realm?

Yes, the same happens, as it is the same realm only updates me the password of the first ...
