[Freeswitch-users] Not send a ptime attr in SDP
I put the Who? in Mishehu

Ivan,
I am indeed familiar with that option in FS. But the point is this:
the demand to have the Contact in e164 format is a very silly demand to
make in the first place. There really isn't any functional reason to
enforce such a restriction.
In other words, providers make illogical demands all the time...
