Modify SIP-Header P-Asserted-Identity

[Pascal Blumenthal]

Hi all

I have a problem to modify the P-Asserted-Identity with my Cisco CUBE.

I want to change the value from <sip:+41yyyyyyyyy@xxx.xxx.xxx.xxx> to <tel:+41yyyyyyyyy@xxx.xxx.xxx.xxx>

I have the following SIP Profile:

voice class sip-profiles 100
 request ANY sip-header P-Asserted-Identity modify "<sip:(.*)@.*>" "<tel:\1>"

and this is my Dial-Peer:

dial-peer voice 2100 voip
 description *** dial-peer Provider ***
 translation-profile incoming FROM-PSTN
 destination-pattern +T
 session protocol sipv2
 session target ipv4:xxx.xxx.xxx.xxx
 session transport tcp
 incoming called-number +41yyyyy....
 voice-class codec 1 
 voice-class sip srtp-auth sha1-32
 voice-class sip profiles 100
 dtmf-relay rtp-nte
 no vad

Can anybody explain me why the Cube doesn't modify my P-ID?

Thank you very much for your help.

Cheers,

Pascal

You configuration should look as follow:

voice class sip-profiles 100
 request ANY sip-header P-Asserted-Identity modify "P-Asserted-Identity:(.*<)sip:(.*)" "P-Asserted-Identity:\1tel:\2"

[Pascal Blumenthal]

Hi Mohammed

Thank you for your answer but unfortenately, my CUBE doesn't change any value in the P-Asserted Identity Field.

Any other suggestions?

Best regards,

Pascal

I just tested this in my lab and got it working. Make sure that your are matching the correct outgoing dialpeer. Please post the entire config and the output of debug voice dialpeer all.

Config

voice class sip-profiles 1
 request ANY sip-header P-Asserted-Identity modify "P-Asserted-Identity:(.*)<sip:(.*)" "P-Asserted-Identity:\1<tel:\2"

!

dial-peer voice 717 voip
 destination-pattern xxxxxxxxxx
 session protocol sipv2
 session target ipv4:x.x.x.x
 voice-class sip asserted-id pai

Hi Mohammed

You are right...it works. I was looking at the wrong dial-peer.

Thank you very much for your help.

Hi Mohammed,

I just have the same problem that I want to modify the "P-Asserted-Identity" as the provider expect a special value.

The "normal" unmodified P-Asserted-Identity looks like this

P-Asserted-Identity: "username" <sip:XXXX77@x.x.x.x>

I want to change this P-Asserted-Identity to this one

P-Asserted-Identity: "username"<sip:YYYYYYYY77@y.y.y.y:5060>

X = internal DN
x = internal IP of CUCM
Y = external DN
y = external IP

I tried to do this with this config

voice class sip-profiles 1
request ANY sip-header P-Asserted-Identity modify "P-Asserted-Identity:(.*)<sip:XXXX77@x.x.x.x>" "P-Asserted-Identity:\1<sip:YYYYYYYY77@y.y.y.y:5060>"

dial-peer voice 11 voip
 description SIP-Outgoing
 translation-profile incoming SipInbound
 translation-profile outgoing SipOutbound
 destination-pattern 0T
 modem passthrough nse codec g711alaw
 session protocol sipv2
 session target ipv4:y.y.y.y
 session transport udp

 fax nsf 000000
 fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback pass-through g711alaw
 no vad
!


In the log I also see that dialpeer 11 should be used:


*Jun 16 15:16:31.242 MESZ: //-1/xxxxxxxxxxxx/DPM/MatchNextPeer:
   Result=Success(0); Outgoing Dial-peer=11 Is Matched

But the problem is that the P-Asserted-Identity is not modified and still the default value.

Would did I wrong?

hello all,

I am new to SIP profiles, so I am trying to only change the username in the P-asserted-identity field.  

thanks
