[SR-Users] Remving ISUB tag in FROM field

[Alex rsm]

Hi,

Our openSER proxy is receiving SIP messages from PBX devices. The PBX includes its extension in the FROM field of the SIP message. 
Is there any function in the openSER to strip off the PBX extension (anything after username and before @domain)?

Is uac_replace_from( ) function is the right one?
