custom field in sip message

Evgeny Andreev — Sun, 17 Mar 2019 20:17:54 GMT

Hello

sip app - SIP - cisco router voice bundle - SIP - genesys sip server

if i initiate call from sip app to genesys server with custom field in INVITE message (ClientCode: 123456), i couldn't see it on genesys server. On cisco router i see this field only in INVITE from sip app.

Voice call works fine

sip app - SIP - genesys sip server

in thist topology custom field is recieved on genesys server

dial-peers on router

dial-peer voice 121 voip
description **** MOBILE APP ***
destination-pattern 7800
session protocol sipv2
dtmf-relay cisco-rtp h245-alphanumeric h245-signal rtp-nte
codec g711alaw
no vad

dial-peer voice 100 voip
description ***GENESYS SIP SERVER***
huntstop

destination-pattern 9[0,9].
session protocol sipv2
session target ipv4:172.28.240.56
dtmf-relay rtp-nte
codec g711alaw
no vad

Any ideas why cisco router cuts custom field??

Best regards

Can you show the complete INVITE please ? You should be able to match the header against a sip profile and use a copy list to add it back when the INVITE is sent out. CUBE does a check and drops unsupported information so what you see if working as designed AFAIK.

Just wondering, why do you have session protocol sipv2 on dial-peer 121, obviously trying to make this a SIP dial-peer, but then have H323 DTMF relay configured?

Configure voice class

voice class sip-hdr-passthrulist 10
passthru-hdr ClientCode

Under the inbound dial-peer put this command

voice-class sip pass-thru headers 10
