Frequently Asked Questions PBX Networking bution can be configured for system access only in the Configurator (Telephony: Call Distribution menu). A specific MSN can be seized for individual calls by means of a code number procedure. For further information, refer to the "OpenCom 100 / Aastra 800, Operation on Standard Terminals" user guide. Question: What are some of the causes for problems when sending and/or receiving faxes? In frequent cases, the reason may be found in a problem with the ISDN-L1 reference clock distribution. The L1 clock is delivered from the network provider. An unclean L1 clock distribution and the introduced signalling jitter is overheard by the human ear. Nevertheless, data and fax transmissions may be disturbed by the jitter. Please check, which ISDN lines will deliver the L1 clock. Details can be found under L1 Clock starting on page 155. The fax data transfer possibly is routed via a compressing VoIP connection. Please verify, if the a/b port is configured with the "Fax" setting. For the VoIP connection, select a VoIP profile which includes the non-compressing G.711 codec. 19.3 PBX Networking Question: Why is it not possible to answer calls from another communications system via the missed calls list? You get a call e.g. via a direct Q.SIG connection. Which line seizure codes you will need to dial for the callback is not included automatically in the information transferred with Q.SIG. Therefore, you need to setup the callback in the bundle configuration. Call up the Telephony: Trunks: Bundle page. Change the desired Q.SIG bundle and enter the line seizure code for the callback in the Prefix for source phone number at incoming internal input field. Question: Why is it not possible to reach a communications system indirectly via another communications system? You have interconnected e.g. three communications system with two direct Q.SIG connections. While configuring the routes, you applied the default "Business" selection for the Type setting. Call-switching for internal calls is possible for the inbetween communications system for internal routes only. Change the Type setting for all affected routes to "Internal". 221

You have interconnected e.g. three communications system with two direct Q.SIG

connections. While configuring the routes, you applied the default “Business”

between communications system for internal routes only. Change the Type setting
