outgoing IAM message from PGW 9.6(1) with bearer capability set to Unrestricted Digital Information

Hi Experts, Do you know a way to get an outgoing IAM message from PGW 9.6(1) with bearer capability set to Unrestricted Digital Information?

I use PGW as PSTN gateway between a SIP net and TDM. I'm trying to generate an outgoing IAM with bearer cap set to UDI.

Do you know what SIP header can be inserted into an INVITE to get my desidered IAM? SIP-GTD maybe?

Regards.

Re: outgoing IAM message from PGW 9.6(1) with bearer capability

I found a way.

If I add a SIP-GTD header I get an outgoing IAM with bearer capability setted to unrestricted digital information:

INVITE sip:1234@voice.aemcom.net:5060 SIP/2.0
