Blind Attn-Xfer Enable Enables the ATA device to perform an attended transfer operation by ending the current call leg and performing a blind transfer of the other call leg.

To use this feature, select yes. Otherwise, select no.
The default is no.
MOH Server User ID or URL of the auto-answering streaming audio server. When only a user ID is specified, the current or outbound proxy is contacted. Music-on- hold is disabled if the MOH Server is not specified.
Conference Bridge URL
This feature supports external conference bridging for n-way conference calls (n > 2), instead of mixing audio locally. To use this feature, set this parameter to that of the server’s name, for example,
[email protected]:12345 or conf (which uses the Proxy value as the domain). This field is found on the SPA2102 and PAP2T only.
Conference Bridge Ports
Select the maximum number of conference call participants. The range is 3 to 10. The default is 3. This field is found on the SPA2102 and PAP2T only.
Field Description
Proxy SIP proxy server for all outbound requests.
Outbound Proxy SIP Outbound Proxy Server where all outbound requests are sent as the first hop.
Use OB Proxy In Dialog
Whether to force SIP requests to be sent to the outbound proxy within a dialog. Ignored if the parameter Use Outbound Proxy is no, or the Outbound Proxy parameter is empty.
The default is yes.
Register Enable periodic registration with the Proxy parameter. This parameter is ignored if Proxy is not specified.
The default is yes.
Make Call Without Reg
Allow making outbound calls without successful (dynamic) registration by the unit. If No, dial tone will not play unless registration is successful. The default is no.
Register Expires Allow answering inbound calls without successful (dynamic) registration by the unit. If proxy responded to REGISTER with a smaller Expires value, the PAP2T will renew registration based on this smaller value instead of the configured value. If registration failed with an Expires too brief error
response, the PAP2T will retry with the value given in the Min-Expires header in the error response.
The default is 3600.
Ans Call Without Reg Expires value in sec in a REGISTER request. The PAP2T will periodically renew registration shortly before the current registration expired. This parameter is ignored if the Register parameter is no. Range: 0 – (231 – 1) sec
Use DNS SRV Whether to use DNS SRV lookup for Proxy and Outbound Proxy. The default is no.
DNS SRV Auto Prefix If enabled, the PAP2T will automatically prepend the Proxy or Outbound Proxy name with _sip._udp when performing a DNS SRV lookup on that name.
The default is no.
Proxy Fallback Intvl This parameter sets the delay (sec) after which the PAP2T will retry from the highest priority proxy (or outbound proxy) servers after it has failed over to a lower priority server. This parameter is useful only if the primary and backup proxy server list is provided to the PAP2T via DNS SRV record lookup on the server name. (Using multiple DNS A record per server name does not allow the notion of priority and so all hosts will be considered at the same priority and the PAP2T will not attempt to fall back after a fail over).
The default is 3600
Proxy Redundancy Method
PAP2T will make an internal list of proxies returned in DNS SRV records. In normal mode, this list will contain proxies ranked by weight and priority. if Based on SRV port is configured the PAP2T does normal first, and also inspect the port number based on 1st proxy’s port on the list.
The default is Normal.
