Cisco 2811 not registering to SIP proxy. SIP Register message edit

[bejoy.cisco]

Dear All,

I am facing this issue with my Cisco 2811 CUBE router. I am trying to register this to my SIP provider's Proxy, without success.

I am able to register X-lite with the SIP proxy from the provider. As per the provider the following must be changed:

The register message that I am sending is as follows:

Sent:
REGISTER sip:siptrunk.ims.zain.bh:5060 SIP/2.0

Via: SIP/2.0/UDP 172.26.3.210:5061;branch=z9hG4bK47F8C
CSeq: 27 REGISTER

As per the provider  in the register message "REGISTER sip:siptrunk.ims.zain.bh:5060 SIP/2.0"   5060 must not be present.

Is there a way that I can edit the register message and remove the 5060 from it.

Regards

Create a SIP profile that does what you need it to do and then apply it to your dial-peer

voice class sip-profiles 1
 request REGISTER sip-header SIP-Req-URI modify "sip:siptrunk.ims.zain.bh:5060 SIP/2.0" "sip:siptrunk.ims.zain.bh SIP/2.0"

dial-peer voice 1 voip
 voice-class sip profiles 1
