### Answer
I don't have information in my sources about restricting an agent to only accept calls from a specific set of phone numbers (such as limiting inbound pickup to 2 allowed numbers) . The sources cover creating a voice agent's configuration options [(1) ](
) and connecting agents to custom telephony via SIP trunking or dial-to-SIP-URI methods [(2) ](
) , but neither describes a caller-number allowlist or restriction feature.
I could try to answer generally based on my own knowledge if you'd like, but I want to flag that it wouldn't be backed by these sources. Otherwise, you may want to check with support directly:
