I don't see + in trace Prepend '+' to Calling Number? y:

Code:

change trunk-group 67                                           Page   4 of  21
                              PROTOCOL VARIATIONS

                      Mark Users as Phone? y
            Prepend '+' to Calling Number? y
      Send Transferring Party Information? y

                    Send Diversion Header? n
                  Support Request History? y
             Telephone Event Payload Type:

trace

Code:

15:53:15 SIP>INVITE sip:[email protected];user=phone SIP/2.0
15:53:15     dial 21171
15:53:15     seize trunk-group 67 member 17  cid 0x2549
15:53:15     Setup digits 21171

15:53:16     idle trunk-group 67 member 17  cid 0x2549

It adds + only if I enable IMS in sip signalling group:

Code:

15:42:53 SIP>INVITE sip:[email protected] SIP/2.0
15:42:53     dial 21171
15:42:53     seize trunk-group 67 member 16  cid 0x1c27
15:42:53     Setup digits 21171
15:42:53     Calling Number & Name 21522 Toropova Anna
15:42:53 SIP<SIP/2.0 100 Trying
15:42:53     Proceed trunk-group 67 member 16  cid 0x1c27
15:42:53 SIP<SIP/2.0 488 MediationCall SetupCall error:  Mediati
15:42:53 SIP<onCall CreateOutgoingSession error.
15:42:53 SIP>ACK sip:[email protected] SIP/2.0
15:42:53     denial event 1204: Bearer cap not implem D1=0xe0011 D2=0x41
15:42:53     idle trunk-group 67 member 16  cid 0x1c27

But I don't need IMS enabled because of bearer capability.

What shall I do to make Prepend '+' to Calling Number? y work?

I use OPS to ring 21171 and +21171 sip number simultaneously.

Hi,

I guess there's a misunderstanding. The CM manual explains the meaning of Prepend "+" to Calling Number as follows:
If enabled, the calling party number in the header of the SIP message is prepended with a plus
sign (+). Available only for sip trunk groups.

In your trace, 21171 was the request-URI (called party number), instead of calling party number hence you will not see "+" in front of it.

If IMS is enabled on signaling group and you use public numbering in SIP trunk group, you will see "+" in front of the request-URI, this works as designed.

Hope it helps,

Regards,
Howard
