PJSIP From Header Display Name

[iotcom]

we have migrated all our sip trunk from chan_sip to pjsip smoothly

but one of our provider no accepting the from header without Display Name

From a packet capture; using chan_sip
From: “+911414975060” sip:+911414975060@rj.ims.airtel.in;tag=f6c50711b4b44df598f23f3dfef98e94

Using PJSIP it looks like
From: sip:+911414975060@rj.ims.airtel.in;tag=9e318a8a-6a55-4902-b1f3-7d9714825ed4

Asterisk 18.13.0
PJPROJECT version currently running against: 2.12

On any case it will be the same number
