I am trying to manipulate CONTACT header on a Voice trunk with an HMR rule, I am able to do so successfully when the the original contact is formated with a calling number, however my issue is that when there is no calling number my match is invalid because there is no @, I can rewrite the whole header but the I have to specify the IP address and I don't want to do that so that I have the options to dynamically assign and IP address, I am having trouble writing a match statement that would work, and I not sure how to define a variable for the IP address
original contact:
Contact: <sip:1.1.1.1:5060;transport=UDP>
Contact: <sip:8885551234@1.1.1.1:5060;transport=UDP>
desired result:
Contact: <sip:12345678@1.1.1.1:5060;transport=UDP>
config
message-rule CONTACT_HEADER message-type any 10
modify header contact position first match /sip:.*@/ new-value /sip:12345678@/
maybe something like thi
message-rule CONTACT_HEADER message-type any 10
modify header contact position first match /sip:.*:/ new-value /sip:12345678@<ip address>:/
